PIN NAME
FUNCTION
INTERFACE
8
RF AGC
An output terminal for RF AGC.
A pull up resister is required because of its
open collector output. A de-coupling capacitor
is also connected to reduce noise.
9
1’st SIF IN
An input terminal for 1’st SIF signal.
10
IF AGC
A terminal should be connceted to an IF AGC
filter. Connect 2.2uF capacitor to Vcc.
11
APC FILTER
A terminal should be connected with an APC
filter for chroma demodulation.
This terminal voltage controls the frequency
of VCXO.
12
X’TAL
A terminal should be connected with a
(4.43MHZ)
4.433619MHz X’tal oscillator. The oscillated
signal leads to the chroma demodulation, H
out frequency tuning, AFT, etc.
