Address setting pin
The address of the PLL block Is set
up using the voltage applied to this
pin.
This Is power supply for the PLL
circuit.
This Is the ground pin for the PLL
circuit.
Crystal oscillator input pins.
A 4MHz crystal is used.
This Is power supply for the Band
circuit.
The output port of the band block can
be set up using the control data.
Bear in mind that drive current differs
according to each band drive port.
This Is power supply for the Mixer
circuit.
Be sure to connect a resistance (of
about 33kΩ) between pin18 and the
33V external power supply for tuning.
To prevent abnormal oscillation,
connect between pin18 and GND a
capacity element that does not affect
a PLL.
