| 14 PDI Charge pump output of the phase detector which constitutes the PLL. High level is output when the
divided local oscillator frequency is high than the reference frequency.
15 PD2 In the opposite case, low level is output. Floating occurs when the frequencies matched.
The output is applied to the variable capacitor diode in the local oscillator through the low pass
filters.
a
16 Vss Ground terminal.
