The f characteristic of a
loop in the locked state
can be set by R.
Normally, set fc in the
range of 100 to 150kHz.
Dynamic AGC circuit is
used to improve AGC
response characteristics.
Set a filter constant to
avoid a sag around

.
RFAGC delay point is set
by the voltage applied to
this pin.
Input resistance is 1k
.
Input capacitance is 7pF.
