VHF oscillator

4
UHF oscillator
5
VHF oscillator.
To prevent abnormal oscillation,
connect a resistor between pin 16 and
the external capacitor.
UHF oscillator.
Pin 5 uses both as band
switch.Connecting pin 5 to VCC via
22ksets to UHF ; connecting pin 12
to GND sets to VHF.
To use VHF SW voltage OPEN rather
than GND, connect a resistor of
around 10k. Changing capacitor of
6pF connected to pins 2 and 5 of test
circuit 2 varies the oscillation
frequency range.
Be careful not to set the constant too
large, because abnormal oscillation
may occur.
