Set the output for ROUT, GOUT and BOUT for reception at high impedance.
Make the wiring from ROUT, GOUT and BOUT to the power amplifier as short as possible.
Connect the Vcc5, Vcc12 and VREF decoupling capacitors so that the ceramic capacitor and electrolytic
capacitor are connected in parallel and the distance from the IC is less than 3mm.
Connect the clamp capacitors for RIN, GIN and BIN so that the distance from the IC is as short as
possible.
Input the signals to RIN, GIN and BIN at low impedance via a clamp capacitor.
Set the output to OFF when the VDET/CSYNC output is not used. (Otherwise, this may cause the
crosstalk to deteriorate.)
The VREF output cannot be used as an external power supply.
Turn the power on in the order of 5V

When applying blanking to the video period, the blanking pulse input to the BLK pin should have a high
level of 4.7V or more.
