NJ88C30, VHF SYNTHESISER

Crystal Oscillator and Reference Divider The Reference oscillator consists of a Pierce type oscillator intended for use with a parallel resonant fundamental crystal.

Typical gain and phase characteristics for the oscillator inverter are shown in Fig 5.

An external reference oscillator may be used by
