Pin to apply time constant of
envelope detection for RF AGC.
Optimum load resistance across
Vcc is 150k .
AGC output pin for PB VIDEO
signal (Max. gain of AGC AMP is
about 7dB).
Control signal input pin for RF SW
switching:
Input pin for RF switch and 12dB
AMP.
Dropout detection signal output
pin; High upon dropout.
Input pin for RF switch and 12dB
AMP.
Pin to connect time constant of
dropout detection.
High (over 3V): selects RF IN A
Low (under 0.3V):
