FACTORY PROGRAMMED OSCILLATORS
XOPL91 SERIES
Low Jitter 7mm x 5mm SMD
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 85°C. 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 .
