BASIC APPLICATION CIRCUIT EXAMPLES
1) Application Circuit for FIFO-1 and FIFO-2 Modes
• Connect the M7664 decoder and a video LSI device according to the output interface (ITU-
• 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
• If the input is limited to the composite signal, connect VIN (5:6), VRT2, VRB2, AMPOUT2,
• 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.
