LA7565E, 7565KM
Sample Application Circuit (2)
When the SIF, first SIF, AFT, and RF AGC circuits are not used.
• When the SIF circuit is not used:
Leave pins 1, 23, and 24 open.
Insert a 2-kΩ resistor between pin 2 and ground.
• When the first SIF circuit is not used:
Leave pins 3, 4, 15, and 22 open.
Connect pin 16 to ground.
• When the AFT circuit is not used:
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.
• When the RF AGC circuit is not used:
Leave pins 14 and 21 open.
A 0.01-µF capacitor must be inserted between pin 21 and ground to prevent oscillation.
