Frequency generator

The frequency generator is implemented as a conventional phase locked loop
controlled synthesiser. In simplex versions of F800, one frequency generator produces
local oscillator signal for the receiver and also the transmitter carrier. In duplex
versions, one frequency generator is used for local oscillator and one frequency
generator is used to produce the transmitter carrier.

The following circuits are the major parts of the frequency generator used in simplex
versions:

#"

VCO, Voltage Controlled Oscillator.

#"

PLL, synthesiser circuit

#"

Prescaler

#"

Loop filter

#"

Crystal reference oscillator

#"

Buffer stage

In duplex versions two frequency generators are used. Both generators are built with
the same blocks as used in the simplex generator as indicated above.
