PNP open collector method is used.
Band switching outputs
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
Filter input
(Charge pump output)
phase of the programmable divider output (f 1/N) is ahead compared to the
reference frequency (fref), the "source" current state becomes active.
If it is behind, the "sink" current becomes active.
If the phases are the same, the high impedance state becomes active.
Power supply voltage 3 Power supply voltage for tuning voltage 28 to 35V
When 19 bit data is input,lock detector is output.
When 27 bit data is input, lock detector is output, the programmable freq.
Divider output and reference freq.
Output is selected by the test mode.
This is normally at a "L". When this is at "H", data and clock signals are received.
Data is read into the latch when the 19th pulse of the clock signal falls.
This is connected to the
crystal oscillator
4.0MHz crystal oscillator is connected.
