Pin No.
Function
Description
Equivalent circuit
45
IF output
The IF amplifier load
Pin 40 VCC

Q1: Used for time constant
switching during seeks.
τ = 2.2 F × 300 k
Seek
44
IF AGC
τ = 2.2 × 10
The external capacitors are
connected to VCC.
This is because the IF amplifier
operates referenced to VCC.
AM antenna damping
I46 = 6 mA (maximum)
46
drive output
This is the antenna damping
Wide band AGC input
current.
