FEATURES

GENERAL SPECIFICATION

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 .

OUTLINE & DIMENSIONS

PRODUCT SELECTION

* The frequency stability parameter is an inclusive figure and includes

adjustment tolerance at 25°C, stability over operating temperature

range, variations due to load change ±10%, supply voltage change

±10%, first year ageing, shock and vibration.
