Surface Mount
LVPECL
Clock Oscillator
Description:
The Connor Winfield Pxxx - Series are
5.0x7.0mm Surface Mount, LVPECL, Fixed
Frequency Crystal Controlled Oscillator
(XO) designed for applications requiring
tight frequency stability, wide temperature range
and low jitter. Operating at 2.5V or 3.3V supply
voltage, the Pxxx - Series provides an LVPECL
Differential Outputs with enable / disable function.
The surface mount package is designed for
high-density mounting and is optimum for mass
production.
