Pin No.
Pin name
Pin function
25
FILTER CONTROL Internal filters (i.e. sound carrier BPF and sound
CAPACITOR
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.
Equivalent circuit
26
NC
Not connected.
27
SIF PLL FILTER Pin 27 is the SIF PLL filter pin.
Normally use the following values.
R: 3k
C1: 0.01µF
C2: 1000pF
Large R value
Small R value
A large R value (6kor lower) results in high-pass
FM detection output noise. A smaller R value
results in low-pass noise.
