Si5332 Data Sheet
6/8/12-Output Any-Frequency Clock Generator
Based on Silicon Labs proprietary MultiSynth flexible frequency synthesis technology,
the Si5332 generates any combination of output frequencies with excellent jitter perfor-
mance (190 fs rms). The device's highly flexible architecture enables a single device to
generate a wide range of integer and non-integer related frequencies on up to 12 differ-
ential clock outputs with 0 ppm frequency synthesis error. The device offers multiple
banks of outputs that can each be tied to independent voltages, enabling usage in
mixed-supply applications. Further, the signal format of each clock output is user-config-
urable. Given its frequency, format, and supply voltage flexibility, the Si5332 is ideally
suited to replace multiple clock ICs and oscillators with a single device.
The Si5332 is quickly and easily configured using ClockBuilder Pro software. Clock-
Builder Pro assigns a custom part number for each unique configuration. Devices
ordered with custom part numbers are factory-programmed free of charge, making it
easy to get a custom clock uniquely tailored for each application. Using the Si5332's I2C
interface, the device may be user-configured at power-up or internally-configured NVM
programmed with new configuration using the ClockBuilder Pro Field Programmer.

3. Functional Description
The Si5332 is a high-performance, low-jitter clock generator capable of synthesizing up to twelve user-programmable clock frequencies
up to 333.33 MHz. The device supports free run operation using an external or embedded crystal, or it can lock to an external clock
signal. The output drivers support up to twelve differential clocks or twenty four LVCMOS clocks, or a combination of both. The output
drivers are configurable to support common signal formats, such as LVPECL, LVDS, HCSL, and LVCMOS. VDDO pins are provided for
versatility, which can be set to 3.3 V, 2.5 V, 1.8 V or 1.5 V (CMOS only) to power the multi-format output drivers. The core voltage
supply (VDD) accepts 3.3 V, 2.5 V, or 1.8 V and is independent from the output supplies (VDDOxs). Using its two-stage synthesis archi-
tecture and patented high-resolution low-jitter MultiSynth technology, the Si5332 can generate an entire clock tree from a single device.
The Si5332 combines a wideband PLL with next generation MultiSynth technology to offer the industry’s highest output count high per-
formance programmable clock generator, with attainable jitter performance below 200 fs RMS. The PLL locks to either an external
16-50 MHz crystal or an embedded 50 MHz crystal for generating free-running clocks or to an external clock (CLKIN_2/CLKIN_2# or
CLKIN_3/CLKIN_3#) for generating synchronous clocks. In free-run mode, the oscillator frequency is multiplied by the PLL and then
divided down either by an integer divider or MultiSynth for fractional synthesis.
The Si5332 features user-defined universal hardware input pins which can be configured in the ClockBuilder Pro software utility. Uni-
versal hardware pins can be used for OE, spread spectrum enable, input clock selection, output frequency selection, or I2C address
select.
The device provides the option of storing a user-defined clock configuration in its non-volatile memory (NVM), which becomes the de-
fault clock configuration at power-up. To enable in-system programming, a power up mode is available through OTP which powers up
the chip in an OTP defined default mode but with no outputs enabled. This allows a host processor to first write a user defined subset of
the registers and then restart the power-up sequence to activate the newly programmed configuration without re-downloading the OTP.

The Si5332-GM1 features:
Up to six differential clock outputs with individual VDDO.
Five user-configurable HW input pins, defined using ClockBuilder Pro.
3.2 Modes of Operation
The Si5332 supports both free-run and synchronous modes of operation. The default mode selection is set in ClockBuilder Pro. Alterna-
tively, two universal hardware input pins can be defined as CLKIN_SEL[1:0] to select between a crystal or clock input. There is also the
option to select the input source via the serial interface by writing to the input select register.
3.2.1 Initialization
Once power is applied, the device begins an initialization period where it downloads default register values and configuration data from
NVM and performs other initialization tasks. Communicating with the device through the serial interface is possible once this initializa-
tion period is complete. The clock outputs will be squelched until the device initialization is done.
3.3 Frequency Configuration
The phase-locked loop is fully integrated and does not require external loop filter components. Its function is to phase lock to the selec-
ted input and provide a common synchronous reference to the high-performance MultiSynth fractional or integer dividers.
A cross point mux connects any of the MultiSynth divided frequencies or INT divided frequencies to individual output drivers or banks of
output drivers. Additional output integer dividers provide further frequency division by an even integer from 1 to 63. The frequency con-
figuration of the device is programmed by setting the input dividers (P), the PLL feedback fractional divider (Mn/Md), the MultiSynth
fractional dividers (Nn/Nd), and the output integer dividers (R). Silicon Labs’ Clockbuilder Pro configuration utility determines the opti-
mum divider values for any desired input and output frequency plan

Functional Description

3.4 Inputs
The Si5332 requires an external 16-50 MHz crystal at its XIN/XOUT pins or the embedded 50 MHz crystal to operate in free-run mode,
or an external input clock (CLKIN_2/CLKIN_2# or CLKIN_3/CLKIN_3#) for synchronous operation. An external crystal is not required in
synchronous mode.
3.4.1 External Reference Input (XA/XB)
An external crystal (XTAL) is used in combination with the internal oscillator (OSC) on Si5332A/B/C/D to produce a low jitter reference
for the PLL when operating in the free-run mode. The Si5332 Reference Manual provides additional information on PCB layout recom-
mendations for the crystal to ensure optimum jitter performance. Refer to Table 5.4 External Crystal Input Specification on page 24 for
crystal specifications.
For free-running operation, the internal oscillator can operate from a low-frequency fundamental mode crystal (XTAL) with a resonant
frequency of 16 to 50 MHz. A crystal can easily be connected to pins XA and XB without external components, as shown in the figure
below. Internal loading capacitance (CL) values from 2.5 pf to 21.5 pf can be selected via register settings. Alternatively, an external CL
can be used along with the internal CL.

Figure 3.4. External Reference Input (XA/XB)
The Si5332E/F/G/H options feature an embedded 50 MHz reference crystal that is used in the free run mode.
3.4.2 Input Clocks
An input clock is available to synchronize the PLL when operating in synchronous mode. This input can be configured as LVPECL,
LVDS or HCSL differential, or LVCMOS. The recommended input termination schemes are shown in the Si5332 Family Reference
Manual. Differential signals must be AC coupled. Unused inputs can be disabled by register configuration.
3.4.3 Input Selection
The active clock input is selected by register control, or by defining two universal input pins as CLKIN_SEL[1:0] in ClockBuilder Pro. A
register bit determines input selection as pin or register selectable. If there is no clock signal on the selected input at power up, the
device will not generate output clocks.
In a typical application, the Si5332 reference input is configured immediately after power-up and initialization. If the device is switched
to another input more than ±1000 ppm offset from the initial input, the device must be recalibrated manually to the new frequency, tem-
porarily turning off the clock outputs. After the VCO is recalibrated, the device will resume producing clock outputs. If the selected inputs
are within ±1000 ppm, any phase error difference will propagate through the device at a rate determined by the PLL bandwidth. Hitless
switching and phase build-out are not supported by the Si5332.

3.5 Outputs
The Si5332 supports up to 12 differential output drivers. Each output can be independently configured as a differential pair or as dual
LVCMOS outputs. The 8-output and 12-output devices feature banks of outputs, with each bank sharing a common VDDO.
Table 3.1. Clock Outputs
Device/Package Maximum Outputs
Si5332-GM1 (32-QFN) 6 Differential, 12 LVCMOS
Si5332-GM2 (40-QFN) 8 Differential, 16 LVCMOS
Si5332-GM3 (48-QFN) 12 Differential, 24 LVCMOS
The output stage is different for each of the three versions of Si5332.
The 6-output device features individual VDDO pins for each clock output. Each clock output can be sourced from MultiSynth0, Multi-
Synth1, the input reference clock, or one of the five INT dividers through the cross point MUX.
The 8-output device includes four clock outputs with dedicated VDDO pins, each of which can be sourced from MultiSynth0, Multi-
Synth1, the input reference clock, or one of the five INT dividers through the cross point MUX. The remaining four clock outputs are
divided into Bank A and Bank B. Each Bank of outputs can be sourced from MultiSynth0, MultiSynth1, the input reference clock, or
one of the five INT dividers through the cross point MUX. The outputs within each of the two Banks share a common VDDO pin.
The 12-output device includes two clock outputs with dedicated VDDO pins, each of which can be sourced from MultiSynth0, Multi-
Synth1, the input reference clock, or one of the five INT dividers through the cross point MUX. The remaining ten clock outputs are
divided into Bank A, Bank B, Bank C, and Bank D. Each Bank of outputs can be sourced from MultiSynth0, MultiSynth1, the input
reference clock, or one of the five INT dividers through the cross point MUX. The outputs within each of the four Banks share a
common VDDO pin.
Utilizing the reference clock enables a fan-out buffer function from an input clock source to any bank of outputs.
Individual output Integer output dividers (R) allow the generation of additional synchronous frequencies. These integer dividers are con-
figurable as divide by 1 (default) through 63.
3.5.1 Output Signal Format
The differential output swing and common mode voltage are compatible with a wide variety of signal formats including HCSL, LVDS
and LVPECL. In addition to supporting differential signals, any of the outputs can be configured as LVCMOS drivers, enabling the de-
vice to support both differential and single-ended clock outputs. Output formats can be defined in ClockBuilder Pro or via the serial
interface.

3.5.2 Differential Output Terminations
LVDS Driver Termination
For a general LVDS interface, the recommended value for the differential termination impedance (ZT) is between 90 Ω and 132 Ω. The
actual value should be selected to match the differential impedance (Z0) of the transmission line. A typical point-to-point LVDS design
uses a 100 Ω parallel resistor at the receiver and a 100 Ω differential transmission-line environment. In order to avoid any transmission-
line reflection issues, the components should be surface mounted and must be placed as close to the receiver as possible. The stand-
ard LVDS termination schematic as shown in Figure 3.5 Standard LVDS Termination on page 12 can be used with either type of
output structure. Figure 3.6 Optional LVDS Termination on page 12, which can also be used with both output types, is an optional
termination with center tap capacitance to help filter common mode noise. The capacitor value should be approximately 0.01 to 0.1 μF.
If using a non-standard termination, please contact Silicon Labs to confirm if the output structure is current source or voltage source
type. In addition, since these outputs are LVDS compatible, the input receiver’s amplitude and common-mode input range should be
verified for compatibility with the output.

Termination for 3.3 V LVPECL Outputs
The clock layout topology shown below is a typical termination for LVPECL outputs. The two different layouts mentioned are recom-
mended only as guidelines. The differential outputs generate ECL/LVPECL compatible outputs. Therefore, terminating resistors (DC
current path to ground) or current sources must be used for functionality. These outputs are designed to drive 50 Ω transmission lines.
Matched impedance techniques should be used to maximize operating frequency and minimize signal distortion. Figure 3.7 3.3 V
LVPECL Output Termination, Option 1 on page 13 and Figure 3.8 3.3 V LVPECL Output Termination, Option 2 on page 13 show
two different layouts. Other suitable clock layouts may exist, and it would be recommended that the board designers simulate to guar-
antee compatibility across all printed circuit and clock component process variations.

3.5.4 LVCMOS Output Signal Swing
The signal swing (VOL/VOH) of the LVCMOS output drivers is set by the voltage on the VDDO pin for the respective bank.
3.5.5 LVCMOS Output Polarity
When a driver is configured as an LVCMOS output it generates a clock signal on both pins (OUTx and OUTxb). By default, the clock on
the OUTxb pin is generated in phase with the clock on the OUTx pin. The polarity of these clocks is configurable enabling complimenta-
ry clock generation and/or inverted polarity with respect to other output drivers.
3.5.6 Output Enable/Disable
The universal hardware input pins can be programmed to operate as output enable (OEb), controlling one or more outputs. Pin assign-
ment is done using ClockBuilder Pro. An output enable pin provides a convenient method of disabling or enabling the output drivers.
When the output enable pin is held high all designated outputs will be disabled. When held low, the designated outputs will be enabled.
3.5.7 Differential Output Configurable Skew Settings
Skew on the differential outputs can be independently configured. The skew is adjustable in 35 ps steps across a range of 245 ps.
3.5.8 Synchronous Output Disable Feature
Output clocks are always enabled and disabled synchronously. The output will wait until a clock period has completed before the driver
is disabled. This prevents unwanted runt pulses from occurring when disabling an output.

3.6 Spread Spectrum
To help reduce electromagnetic interference (EMI), the Si5332 supports spread spectrum modulation. The output clock frequencies can
be modulated to spread energy across a broader range of frequencies, lowering system EMI. The Si5332 implements spread spectrum
using its patented MultiSynth technology to achieve previously unattainable precision in both modulation rate and spreading magnitude.
Spread spectrum can be enabled through I2C, or by configuring one of the universal hardware input pins using ClockBuilder Pro.
The Si5332 features both center and down spread spectrum modulation capability, from 0.1% to 2.5%. Each MultiSynth is capable of
generating an independent spread spectrum clock. The feature is enabled using a user-defined universal hardware input pin or via the
device I2C interface. Spread spectrum can be applied to any output clock derived from a MultiSynth fractional divider, with any clock
frequency up to 250 MHz. Since the spread spectrum clock generation is performed in the MultiSynth fractional dividers, the spread
spectrum waveform is highly consistent across process, voltage and temperature. The Si5332 features two independent MultiSynth di-
viders, enabling the device to provide two independent spread profiles simultaneously to the clock output banks.
Spread spectrum is commonly used for 100 MHz PCI Express clock outputs. To comply with the spread spectrum specifications for PCI
Express, the spreading frequency should be set to a maximum of 33 kHz and –0.5% down spread. A universal hardware input pin can
be configured to toggle spread spectrum on/off.
3.7 Universal Hardware Input Pins
Universal hardware input pins are user configurable control input pins that can have one or more of the functions listed below assigned
to them using ClockBuilder Pro.
Universal hardware input pins can be utilized for the following functions:
Table 3.2. Universal Hardware Input Pins
Description Function
SSEN_EN0 Spread spectrum enable on MultiSynth0 (N0).
SSEN_EN1 Spread spectrum enable on MultiSynth0 (N1).
FS_INTx Used to switch an integer output divider frequency from frequency A to frequency B.
FS_MSx Used to switch a MultiSynth output divider output from frequency and/or change spread
spectrum profile.
OE Output enable for one or more outputs.
I2C address select Sets the LSB of the I2C address to either 0 or 1.
CLKIN_SEL[1:0] Selects between crystal or clock inputs.
Spread Spectrum Enable Pins (SSEN[1:0])
Spread_EN[1:0] pins are active pins that enable/disable spread spectrum on all outputs that correspond to MutliSynth0 or MultiSynth1,
respectively. The change in frequency or spread spectrum will be instantaneous and may not be glitch free.
Table 3.3. SSEN_EN Pin Selection Table
SSEN_ENx
0 Spread Spectrum disabled on MultiSynthx
1 Spread Spectrum enabled on MultiSynthx
Output Frequency Select Pins
There are five integer dividers, one corresponding to each of the five output banks. Using ClockBuilder Pro, a universal hardware input
pin can be assigned for each integer divider, providing capability to select between two different pre-programmed divide values. Divider
values of every integer from 8 to 255 are available in ClockBuilder Pro for each integer divider.
Si5332 Data Sheet
Functional Description
silabs.com | Building a more connected world. Rev. 1.2 | 17
Table 3.4. FS_INT Pin Selection Table
FS_INTx Output Frequency from INTx
0 Frequency A, as defined in ClockBuilder Pro
1 Frequency B, as defined in ClockBuilder Pro
Output Enable
A universal hardware input pin can be defined to control output enable of a differential output, a bank of differential outputs, or as a
global output enable pin controlling all outputs. Upon de-assertion of an OE pin, the corresponding output will be disabled within 2-6
clock cycles. Asserting an OE pin from disable to enable will take <20 µs for the output to have a clean clock.
Output enabled/disabled for LVCMOS are done in pairs. Each differential buffer True and Compliment output can generate an
LVCMOS clock and the OE pin associated with the True and Compliment output buffer will control the respective LVCMOS pair.
For example: If DIFF0 is configured to be SE1 and DIFF0# is configured to be SE2 and OE1 is the associated OE pin, de-asserting the
OE1 pin will disable both SE1 and SE2 outputs. The disable and enable of the outputs to a known state is glitch free.
I2C Address Pin
This pin sets the LSB of the I2C address. For example, if the I2C address is A6h, setting this pin high will set the I2C address to A7h.
CLKIN_SEL[0:1] Pins
These pins are used to set the input source clock between the input clock channels (Crystal, CLKIN_2/CLKIN_2# or CLKIN_3/
CLKIN_3#). Upon switching the input clock source, the output will not be glitch free. It is intended for the user to set this pin to a known
state before the system is powered up or have the receiver address any unintended output signals when switching to a different input
source clock.
Multi-Profile
Si5332 has the ability to store multiple unique configurations in the same custom part number by enabling multi-profile support in Clock-
Builder Pro after selecting the desired Si5332 device. The ClockBuilder Pro wizard guides users to enter the input/output/feature set
needed for each individual profile configuration, then compiles them together and assigns the necessary number of universal hardware
pins based on the number of profiles entered.
The actual number of profiles supported in a particular design is limited by overall design complexity and NVM size. ClockBuilder Pro
automatically determines the NVM size required for your multi-profile design and will warn if the maximum limit is exceeded.
3.8 Custom Factory Pre-programmed Parts
Custom pre-programmed parts can be ordered corresponding to a specific configuration file generated using the ClockBuilder Pro soft-
ware utility. Silicon Labs writes the configuration file into the device prior to shipping. Use the ClockBuilder Pro custom part number
wizard (http://www.silabs.com/clockbuilderpro) to quickly and easily generate a custom part number for your ClockBuilder Pro configu-
ration file. A factory pre-programmed part will generate clocks at power-up.
In less than three minutes, you will be able to generate a custom part number with a detailed data sheet addendum matching your
design’s configuration. Once you receive the confirmation email with the data sheet addendum, simply place an order with your local
Silicon Labs sales representative. Samples of your pre-programmed device will ship within two weeks.
3.9 I2C Serial Interface
The Si5332 is compatible with rev6 of the I2C specification, including Standard, Fast, and Fast+ modes.
Configuration and operation of the Si5332 can be controlled by reading and writing registers using the I2C . Communication with a 1.8 V
to 3.3 V host is supported. See the Si5332 Family Reference Manual for details.
Si5332 Data Sheet
Functional Description
silabs.com | Building a more connected world. Rev. 1.2 | 18
3.10 In-Circuit Programming
The Si5332 is in-system configurable using the I2C interface by the following two methods:
In-ciruit configuration of device registers after power-up. With this method changes to volatile register memory can be done as re-
quired to produce the desired outputs. This does not alter internal NVM; therefore, register memory changes are lost at power-down.
Refer to the Si5332 Family Reference Manual available on our web site for details.
In-circuit re-configuration of internal NVM. Writing to internal NVM requires the use of the CBPro Field Programmer (CBPROG-DON-
GLE) and CBPro software. See UG286: ClockBuilderPro Field Programmer Kit user's guide available on our web site for more infor-
mation. (One important note: The Si5332 core VDDs (VDD_DIG, VDDA, and VDD_XTAL) must be powered by 3.3 V during in-circuit
NVM programming.)
VDD core voltages (VDD_DIG, VDDA, VDD_XTAL) must be 3.3 V for in-circuit programming. Using VDD core voltage lower than 3.3
V (i.e., 2.5 V or 1.8 V) will not support reliable in-circuit NVM programming.

2. The maximum step size is only limited by the register lengths; however, the MultiSynth output frequency must be kept between 5
MHz and 250MHz.
3. Update rate via I2C is also limited by the time it takes to perform a write operation.
4. Default value is ~31.5 kHz.

Notes:
1. INT jitter generation test conditions fOUT = 156.25 MHz LVPECL.
2. Integer mode assumes that the output dividers (Nn/Nd) are configured with an integer value.
3. Fractional and DCO modes assume that the output dividers (Nn/Nd) are configured with a fractional value and the feedback divid-
er is integer.
4. All jitter data in this table is based upon all output formats being differential. When LVCMOS outputs are used, there is the poten-
tial that the output jitter may increase due to the nature of LVCMOS outputs. If your configuration implements any LVCMOS out-
put and any output is required to have jitter less than 3 ps RMS, contact Silicon Labs for support to validate your configuration
and ensure the best jitter performance.
5. FRAC jitter generation test conditions fOUT = 150 MHz LVPECL.

Notes:
General
1. All dimensions shown are in millimeters (mm) unless otherwise noted.
2. This Land Pattern Design is based on the IPC-7351 guidelines.
Solder Mask Design
1. All metal pads are to be non-solder mask defined (NSMD). Clearance between the solder mask and the metal pad is to be 60 µm
minimum, all the way around the pad.
Stencil Design
1. A stainless steel, laser-cut and electro-polished stencil with trapezoidal walls should be used to assure good solder paste release.
2. The stencil thickness should be 0.125 mm (5 mils).
3. The ratio of stencil aperture to land pad size can be 1:1 for all perimeter pads.
4. A 3×3 array of 0.85 mm square openings on a 1.00 mm pitch can be used for the center ground pad.
Card Assembly
1. A No-Clean, Type-3 solder paste is recommended.
2. The recommended card reflow profile is per the JEDEC/IPC J-STD-020 specification for Small Body Components.
