Surface Mount 5x7mm
LVDS Clock Oscillator
Description:
The Connor Winfield Lxxx - Series is a
5x7 mm 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.

Notes:
1. Includes calibration @ 25°C, frequency stability vs. change in temperature, supply voltage and load variations, shock and vibration and 20 years
aging.
2 When the oscillator is disabled the outputs are at high impedance. Outputs are enabled with no connection on pad 1.
3. Vod is measured with a 100 ohm resistor between the true and the complementary outputs.
4. Duty cycle measured at 50% of output voltage swing..
