NJ88C30
VHF SYNTHESISER
DS3281-1.1
The NJ88C30 contains all the logic needed for a VHF PLL
synthesiser and is fabricated on the GPS high performance, small
geometry CMOS process. The circuit contains a reference oscillator
and divider, a two-modulus prescaler and 4-bit control register, a
12-bit programmable divider, a phase comparator and the
necessary data input and control logic.
