1. Functional diagram

2. Description

The MLX90109 is a single chip RFID transceiver for the

125kHz frequency range. It has been conceived for

minimum system cost and minimum power consumption,

offering all required flexibility for a state of the art AM

transceiver base station. An external coil (L), and capacitor

determines the carrier frequency and the oscillator

frequency of the reader. This eliminates zero modulation

effects by perfect antenna tuning, and avoids the need for

an external oscillator.

The reader IC can easily be switched to power down by

setting the antenna amplitude to zero.

The MLX90109 can be configured to decode the

transponder signal on-chip. In this case the decoded signal

is available through a 2-wire interface with clock and data.

For minimum interface wiring, the non-decoded

transponder signal can also be made available on a single

wire interface.

7. General Description

7.1. Loop Gain Oscillator

The oscillator frequency is locked on the antenna resonance frequency. The clock is derived from the oscillator. In this way,

its characteristics are locked to the transmission frequency. As the antenna is used to determine the carrier frequency, the

antenna is always perfectly tuned to resonance. Consequently the MLX90109 is not sensitive to zero modulation (the so-

called “zero modulation” is the phenomena whereby the tag does modulate properly, but no amplitude modulation can be

observed at the reader coil).

7.2. Peak Detector

The peak detector of the transceiver detects the AM signal generated by the tag. This signal is filtered and amplified by an

on-chip switched capacitor filter before feeding the digital decoder. The same signal is fed back to close the loop of the

antenna voltage.

7.3. Band-Pass Filter

By setting the SPEED pin to VDD or to GND, the filtering characteristics are optimized for either 2 or 4 kbaud. The MLX90109

makes an internal first-order filtering of the envelope that changes according to the setting of the SPEED pin, to fit the

Biphase and Manchester data spectrum:

2kbaud (speed pin to VDD) : 400Hz to 3.6kHz

4kbaud (speed pin to VSS) : 800Hz to 7.2kHz

7.4. Digital demodulator

The MODE pin allows to define whether the MLX90109 will issue directly the filtered data stream on the DATA pin (MODE

floating), or decode it in Manchester (MODE = VDD) or Biphase (MODE = VSS). In these two decoding modes, the MLX90109

issues the tag data on the DATA pin at the rising edge of the clock, which is issued on the CLOCK pin. Both CLOCK and DATA

are open drain outputs and require external pull-up resistors.

7.5. Antenna voltage definition

The MLX90109 is a reader IC working in a frequency range of 100 to 150kHz, and designed for use with a parallel L-C

antenna. This concept requires significantly less current than traditional serial antennas, for building up the same magnetic

field strength.

The voltage on the MODU pin (VMODU) controls the amplitude of the antenna voltage Vant, as follows:

(1)

OSMODUDDant VVVV 

with VOS, the offset relative to the VMODU level.

Note: In order to use the internal driver FET as an ideal current source, the voltage on the coil pin should remain higher than

its saturation voltage (typically 0.5V) for a driver current (Idriver) up to 14mA. As this offset can be as much as 300mV, VMODU

should be higher than 0.8V for a correct operation.

7.6. Power Down mode

By setting VMODU higher than Vpd (preferably to VDD) the MLX90109 goes in power down. The antenna voltage will fade to 0V.

The MLX90109 powers up by pulling VMODU below Vpu.

7.7. Write operation

A sequence of power up / power down periods sets the antenna voltage ON and OFF. This feature allows to simply make an

ON/OFF-keying modulated signal to the transponder.

Typically, VMODU is toggled between VDD and 0.8V. Antenna fade-out is related to the quality factor of the antenna (Qant) and

its start-up takes about 3 carrier periods.

Refer to the section “Typical operating configurations” further in this document for more detailed information and practical

hints.

8. System design parameters

The antenna internal driver is switched on as soon as the antenna voltage V(COIL) drops below VDD (see graphical

representation below). The MLX90109 will inject a current Idriver into the antenna to make its amplitude follow the voltage

on the MODU pin.

In order to make the antenna start swinging on the resonance frequency, the chip needs to provide a positive feedback loop.

This loop requires a minimal voltage swing at the COIL pin in order to be operational (typically 100mVpp). Below this value,

the MLX90109 may not be able to retrieve its clock.

Graph:

Antenna voltage and Driver current during normal operation. VMODU=0.8V for VDD=5V. The dashed curve shows the antenna voltage when

the reader has been powered down. The internal driver current is a square wave with a 45% duty cycle.

8.1. Auto start-up condition

Pulling VMODU, at power on, from 5V to less than Vpu will set the internal driver FET on. Provided the voltage drop on the coil

pin is large enough (as explained above), the feedback loop is closed and the oscillation will increase in amplitude.

To obtain the required positive feedback to start-up the oscillation successfully, the antenna impedance Zant should be larger

than 1k. This is so called “auto start-up condition”.

8.2. Antenna current

The MLX90109 is specified to drive a maximum 14mA antenna drive current (Idriver).

The AC equivalent supply current (IDDant) can be calculated as:

(2)

with  the duty cycle which is typically 45%.

The current that the MLX90109 can inject at each oscillation onto the total antenna current is therefore limited to 9mA.

The actual antenna current that generates the magnetic field can be calculated as:

(3)

DDantantant IQI 

A typical coil quality factor (Qant) value is 23, resulting in antenna currents of about 100mA

This current resonance of the parallel antenna allows to build very low power reader base stations, contrary to serial

antenna based versions. Readers using a serial antenna can leverage their voltage resonance to drive bigger antenna’s for

long distance reading up to 1m, whereas the MLX90109 is designed to drive antennas to obtain a reading distance of 1cm up

to 15cm (6”) (depending on efficiency and dimensions).

From the formula above, it is clear that Qant has no influence on Iant. Increasing Qant is equivalent to reduce the antenna

supply current IDDant, hence it reduces the overall current consumption.

Using the previous formula (6), it is possible to define the proportionality between the total number of ampere-turns,

9. Typical configuration: READ ONLY

9.1. Application diagram

The MLX90109 is a highly integrated reader IC. In the application schematic below, only two resistors to set VMODU are

required, next to the antenna inductance and tune capacitor. Capacitors C1 and CD can be added for a better noise

9.3. Power consumption

If the power consumption is not critical and the reader does not have to be put in power down, the MODU voltage can be

strapped to the required level (between 0.8V and Vpd). However, the power consumption can be reduced by controlling the

voltage on VMODU pin (e.g. with an IO port of a microcontroller).

REVISION 011 - JUNE 19, 2017

3901090109

9.4. Noise cancellation

The read performance of a reader is linked with its robustness versus noise. The IC design has been optimized to get a high

signal-to-noise ratio (SNR). The resonant antenna is a natural band-pass filter, which becomes more effective as its quality

factor Qr increases.

Noise rejection could also be improved by a careful PCB design, and by adding decoupling capacitor(s) on the supply lines.

The most sensitive pins to noise injection are MODU and VDD. Since they directly determine Vant, the noise could be

considered as an amplitude modulation (AM) data from a transponder.

If the noise on both pins were identical, it would cancel out, giving a very noise-insensitive reader. Adding a capacitor C1

between MODU and VDD, together with R1 and R2 yields a high pass filter with a cut-off frequency at:

121 )//(2

CRR

Foffcut 







Typically, such a filter should short all noise in the data spectrum, but for many cases, it might be beneficial to set it to less

than the net frequencies (50Hz, 60Hz). For example: R1=100k, R2=19k (to set VMODU), and C1=220nF gives a cut off

frequency of 45Hz.

9.5. Integrated decoding

The MLX90109 provides the option to have a decoded output. This significantly reduces the complexity of the

microcontroller software.

The data is available when the output clock signal is high. The clock signal has a 50% duty cycle when the data is valid. When

the noise level is stronger than the signal level, for instance when no tag is present in the reader field, the duty cycle will be

random. The microcontroller can use this feature to detect the presence of a tag: in that case, it must allow some asymmetry

on the clock. As the sampling error may be 4μs, it should allow a margin of 8 or 12μs.

Remark that when the MLX90109 picks up a Manchester-encoded signal whereas the MODE pin is strapped to VSS (= Biphase

decoding), the clock will also be asymmetric.

9.6. Close coupling

For very short operating distances, a strong coupling with a tag may drastically reduce the antenna impedance Zant. If the

current (Idriver) driven by the antenna internal driver FET goes higher than 14mA, the antenna voltage Vant may be reduced

and the MLX90109 may be unable to read the transponder.

Coupling effect is application-dependent and must be evaluated case by case.

10. Typical configuration: READ/WRITE ON/OFF keying (FDX-B100)

10.1. Application diagram

The basic principle is to switch the voltage on MODU between 0V and VDD. The antenna will reach its maximum amplitude in

less than 3 periods when MODU is stepped down from VDD to VSS. Setting the chip in power-down (set VMODU up to VDD) will

let the antenna fade-out with a time constant, depending on the antenna’s quality factor Qant. For fast protocols, an

additional drain resistor on MODU controlled by the microcontroller could be used to decrease the fall time (refer to the

application note MLX90109 “100% modulation (ON/OFF Keying)”.

13. FAQ

13.1. Is it possible to make proportional modulation (depth less than 100%) with the

MLX90109?

The amplitude of the MLX90109 antenna can be adjusted on the fly by changing the MODU pin level between VMODU = 0.8V

and Vpd. However, the MLX90109 cannot change instantaneously the voltage on its antenna according to a voltage step on

MODU pin, and a transient waveform will appear on the voltage antenna. This particular waveform may disturb the

transponder and in the worst case (modulation depth more than 20%) the MLX90109 may stop its oscillation.

Using the MLX90109 with proportional modulation (modulation depth less than 100%) is not recommended and supported

by Melexis and must be evaluated case by case.

13.2. How should I read data information from a transponder up to 15cm?

The reading distance depends on the complete system composed by the reader and the transponder. A reading distance

with the MLX90109 transceiver up to 15cm has been demonstrated with a specific reader’s antenna (diameter = 130mm,

Inductance = 44μH, Quality factor Qant = 87.2@125kHz) and a transponder with a credit card size antenna (80 x 50mm).

13.3. Is it possible to increase the output power of the MLX90109 transceiver?

The current flowing through the antenna (IANT) can be maximized by a careful design, respecting the design specification of

the MLX90109 (Auto start-up impedance, the maximum driver current IDRIVER).

The voltage on the antenna cannot be increased as it is limited by the power supply VDD (Vant ≤ VDD-VMODU+Vos). Moreover, as

the MLX90109 uses the same connection (COIL ) for the transmission and the reception, it is not possible to use an external

power transistor supplied with a higher voltage than VDD.

13.4. Are there any specific coils available for the MLX90109 transceiver?

Melexis has developed an 18mm coil which is used on the evaluation board EVB90109. Please contact your sales channel if

you wish to purchase production quantities.

13.5. What are the recommended pull-up values on DATA and CLOCK pins?

The DATA and CLOCK are open-drain drivers which require external pull-up resistors. The values are not critical therefore, to

reduce the general power consumption, we recommend to use high ohmic (100k ohm) pull up resistances.
