Integrated Circuit

Frequency Synthesizer

Description:

The NTE1233 consists of a crystal oscillator, 10 bit divider, phase comparator and a programmable

divided−by−N 9 bit counter constructed with complementary MOS device in one chip monolithic

structure. This device has been designed for use in frequency synthesizers and phase locked loop

applications for CB transceiver requiring low power dissipation and high noise immunity.
