Function
PLL charge pump output
A high level is output when the frequency of the local oscillator signal
Charge pump
PD

divided by N is higher than the reference frequency, and a low level
output
is output when that frequency is lower. This pin goes to the
highimpedance state when the frequencies match.

Equivalent circuit
The input frequency range is 0.4 to 15MHz
The signal is passed directly to the IF counter.
