BW 1¢C7218 (iC121) : PLL Synthesizer
1. The main function descriptions
(1)
It
makes
the
local
oscillation
frequency
by
the
control
data
from
IC201.
(2)
Decode
the
control
signal
and
transmit
the
signal
for
receiving
conditions.
(3)
For
the
best
tuning,
count
the
internal-frequency
and
transmit
the
data
to
1C201.

Fix the chip enable to “H” when inputting (DI) and outputting (DO) the serial data.
Receive the control data from the controller (IC201).
This clock is used to synchronize data when transmitting the data of DI and DO.
Transmit the data from LC7218 to the controller which is synchronized with CL.
Not used.
Receive the tuned signal from 1C102 (LA1836).

This is a terminal of power supply.
PLL charge pump output: When the local oscillator signal frequency is higher than the
reference frequency high level signals will output.
When it is lower than the reference frequency, low level signals will output. When it is
same as reference frequency signals, it will be floating.
