• Connect the M7664 decoder and a video LSI device according to the output interface (ITU-

RBT.656, 8-bit [YCbCr], 16-bit [YCbCr], RGB).

• Video input can be four composite inputs or two S-Video inputs.

• Connect unused video input pins to AGND. If a composite signal is input, the C input side

(video amp, A/D converter, etc.) will be in the OFF operation state.

• If the input is limited to the composite signal, connect VIN (5:6), VRT2, VRB2, AMPOUT2,

ADIN2, and CLPOUT2 pins to AGND. Externally attached components such as capacitors

may be removed.

• Set the MODE[3:0] pins to the prescribed setting.

• Supply power and GND for analog, A/D, and digital circuits on the circuit board should be

separated at the power source wherever possible. Power and GND lines for analog and A/D

circuits must be wide and low impedance.
