Internal filters (i.e. sound carrier BPF and sound
carrier trap) are tuned using the capacitor
connected to pin 25.
A value between 0.47µF and 1µF is considered
desirable taking video S/N, and AM and PM noise
into consideration.
Not connected.
Pin 27 is the SIF PLL filter pin.
Normally use the following values.
A large R value (6kΩ or lower) results in high-pass
FM detection output noise. A smaller R value
results in low-pass noise.
R: 3kΩ
C1: 0.01µF
C2: 1000pF
