AUDIO BIAS
FILTER
Connection pin for a filter used to hold the FM
detector output DC voltage fixed. Normally, a 1
μF
electrolytic capacitor should be used. The
capacitance (CI) should be increased if the low
band (around 50Hz) frequency characteristics
need to be improved.

FILTER
CONTROL C
Internal filter (trap) control pin
Connect a capacitor with a capacitance between
0.47 to 1
μF, depending on the video S/N as well
as the levels of the AM and PM noise.
