The accessory IC series for the video
Video isolation amplifier
BH7673G
●General
BH7673G is the single isolation video amplifier. It can reject the external noise when it receives the signal outside of the
application. It can reduce the influence of the external noise substantially. Because it has high common mode noise
rejection ratio (-60dB Typ.). It is the best for the application of automotives, because it is able to use a wide range of
temperature and it has the high electrostatic discharge rating. Moreover, because the frequency characteristic can
correspond to the Hi-Vision signal, it is at the development to equal to or more than 30 MHz.
●Features
1) The high Electrostatic discharge(ESD) rating (The human body model：±6000V pass)
2) Abele to use a wide range of temperature, from -40℃ to +85℃
3) High common mode rejection ratio(Typ. -60dB, f=20kHz)
4) It is not the degradation of CMRR when inserting ESD resistance at the input terminal.
5) Wide band [suitable for D4 standard] (0dB at f=30MHz)
6) Wide output dynamic range(Typ. 3.8Vpp)
7) High input Impedance(Typ. 150kΩ)
8) Low circuit current consumption(Typ. 4.8mA)
9) Bias input
10) SSOP5 small package
●Applications
The car navigation systems, the car monitor etc.
The signal input to the rear monitor, the picture taking-in from the rear camera and the measure of the noise when pulling
around a video signal out of the substrate.

●Cautions for use
1. The numerical values and data shown here are typical design values, not guaranteed values.
2. The application circuit examples show recommended circuits, but characteristics should be checked carefully before using
these circuits. If any external part constants are modified before use, factors such as variation in all external parts and
ROHM LSI ICs, including not only static characteristics but also transient characteristics, should be fully considered to set
an ample margin.
3. Absolute maximum ratings
If the absolute maximum ratings for applied voltage and/or operation temperature are exceeded, LSI damage may
result. Therefore, do not apply voltage or use in a temperature that exceeds these absolute maximum ratings. If it
is possible that absolute maximum ratings will be exceeded, use a physical safety device such as a fuse and make
sure that no conditions that might exceed the absolute maximum ratings will be applied to the LSI IC.
4. GND potential
Regardless of the operation mode, the voltage of the GND pin should be at least the minimum voltage. Actually check
whether or not the voltage at each pin, including transient phenomena, is less than the GND pin voltage.
5. Thermal design
The thermal design should be done using an ample margin that takes into consideration the allowable dissipation under
actual use conditions.
6. Shorts between pins and mounting errors
When mounting LSI ICs onto the circuit board, make sure each LSI's orientation and position is correct. The ICs may
become damaged if they are not mounted correctly when the power is turned on. Similarly, damage may also result if a
short occurs, such as when a foreign object is positioned between pins in an IC, or between a pin and a power supply or
GND connection
7. Operation in strong electromagnetic field
When used within a strong electromagnetic field, evaluate carefully to avoid the risk of operation faults
8. Place the power supply's decoupling capacitor as close as possible to the VCC pin (PIN 3) and GND pin (PIN 2).
9. The parasitic capacitance of the application board may cause the peak of the frequency characteristic response to occur at
a high frequency. To lower the peak of the frequency characteristic, connect in series resistors having resistance of
several dozen ohm to several hundred ohm as close as possible to the output pin.
10. The attention point when treating HD signal
As shown in reference data Fig.20, BH7673G have the frequency characteristic of equal to or more than 30 MHz but by the
influence with the parasitic capacitance of the application board and so on, a characteristic as in the carrying data isn't
sometimes gotten. The frequency characteristic can be improved in inserting about 2kΩ ~ 3kΩ resistance between the
output terminal and the GND terminal to the case.

●Cautions for selection and use of application parts
Method for determining capacity of input coupling capacitor
The input coupling capacitor and input impedance Zin (=150kΩ) inside the IC composes HPF.
When the cutoff frequency(fc) of HPF takes from 1 Hz to be computed by the following formula (a). The value of the input
coupling capacitor is computed with the degree as much as 1uF (Generally, the fc takes from equal to or less than several Hz).
fc=1 / (2π×C×Zin)・・・・(a)
When evaluating the Sag characteristics and determining the capacity of the capacitor during video signal input, a horizontal
stripe signal called "H bar" (shown in Fig.9) is suitable, and this type of signal is used instead of a color bar signal to evaluate
characteristics and determine capacity.
Fig.9 Example of Screen with Obvious Sag (H-bar Signal)
Method for determining capacity of output coupling capacitor
The HPF is formed in the same way by the output coupling capacitor and the input impedance of the IC which connects with the
following paragraph by the video output terminal, so estimate an output coupling capacitor with necessary capacity according to
the formula (a).
The case of insert serge resistor at VIN and VGND terminals
Use the same value resistance when insert serge resistor(Fig.4 R41 and R51) at video input terminals(max value：1kΩ).
The degradation of CMRR etc are not deteriorating when inserting resistance with the same value.
