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.

1) 2) 3) 4) 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.
