5.0x7.0mm
Surface Mount LVDS
Clock Oscillator Series
Description
The Connor Winfield Lxxx - Series
is a 5x7.5mm 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.

Includes initial tolerance, deviation over temperature, supply and load variations, shock, vibration and 20 years
aging.
When the oscillator is disabled, the outputs are at High Impedance. Output is enabled with no connection on E/D
pad.
Vod measured with 100 ohm resistor between the true output and the complementary output.
Duty Cycle measured at 50% of output swing.
