Pin Function
Internal Circuit
Pins 19 and 20 are VIF input pins.
To reduce the loss of signal through a saw filter,
input registors are set to 2 k
.
VIF amplifier has three capacitive coupling
amplifiers, direct connection from a saw filter is
available.

Connect the decoupling capacitor as close as
possible.

GND
Internal filters (i.e. sound carrier BPF and sound
carrier trap) are tuned using the capacitor
connected to pin 21.
A value between 0.47 F and 1 F is considered
desirable taking video S/N, and AM and PM noise
into consideration.
