Filter input
(Charge pump output)
This is connected to
the crystal oscillator.
PNP open collector method is used.
When the band switching data is "H",the output is ON.
When it is "L",the output is OFF.
This is the output terminal for the LPF input and charge pump output.
When the phase of the programmable divider output (f1/N) is ahead compared to
the reference frequency (f
If it is behind, the "sink" current becomes active.
If the phases are the same, the high impedance state becomes active.
Lock detector is output.
Programmabule freq. Divider output and reference freq. output is selected by the
test mode.
4.0MHz crystal oscillator is connected.
REF), the "source" current state becomes active.
