| NTE1233 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.
