Description:
Model Lxxx - Series
The Connor Winfield Lxxx - Series are
5.0x7.0mm Surface Mount, LVDS, 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 Lxxx - Series provides
an LVDS Differential Outputs with enable /
disable function. The surface mount package
is designed for high-density mounting and is
optimum for mass production.
