• Manufacturer Part Number: la7567b
• Description: Tv And Vcr Vif/sif If Signal-processing Circuit With Pal/ntsc Multi-format Audio Support
• Manufacturer: Sanyo Semiconductor Corporation

Sample Application Circuit
When the SIF, first SIF, AFT, and RF AGC circuits are not used:
• When the SIF circuit is not used:
• When the first SIF circuit is not used:
• When the AFT circuit is not used:
• When the RF AGC circuit is not used:
Leave pins 1, 23, and 24 open.
Connect pin 2 to ground through a 2-kΩ resistor.
Leave pins 3, 4, 15 and 22 open.
Connect pin 16 to ground.
Since there is no way to defeat the AFT circuit, connect a 100-kΩ resistor and a 0.01-µF capacitor in parallel between
pin 13 and ground.
Leave pins 14 and 21 open.
Insert a 0.01-µF capacitor between pin 21 and ground for oscillation prevention.
