FACTORY PROGRAMMED OSCILLATORS
EQXOPL-2000 SERIES Low Jitter 8 pin Dual-in-Line Programmable Oscillators
DESCRIPTION
The Euroquartz range of factory programmable oscillators provide custom frequency and specification oscillators within very short lead times. The parts are very reliable in use and have stabilities from 25ppm over -40 to 85C. In addition to the stability over operating temperature range customers may also choose from supply voltages of 2.7, 3.3 and 5.0 Volts, Enable/Disable or Power Down functions and output synchronous or asynchronous .
