Pin 4 & 5 are each base pin of
differential amplifier for 1st LO
oscillator. These pins should be
equipped with LC and varactor
to oscillate on 1 636.80 MHz as
VCO.

Pins of active loop filter for
tuning voltage output.
The active transistors
configured with darlington pair
are built on chip. Pin 11 should
be pulled down with external
resistor. Pin 9 to 10 should be
equipped with external RC in
order to adjust dumping factor
and cutoff frequency. This
tuning voltage output must be
connected to varactor diode of
1st LO-OSC.
