PLL charge pump output
When the frequency generated by dividing the local oscillator
frequency by N is higher than the reference frequency, a high
level is output from the PD pin.
Similarly, when that frequency is lower, a low level is output.
The PD pin goes to the high impedance state when the
frequencies match.

IF counter
Accepts an input in the frequency range 0.4 to 12MHz.
The input signal is directly transmitted to the IF counter.
The result is output starting the MSB of the IF counter using the
DO pin.
Four measurement periods are supported: 4, 8, 32, and 64ms.
