Surface Mount 5x7mm
LVDS Clock Oscillator
Description:
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.

Example: Part Number
L143-155.52M = LVDS Output,
0 to 70, +/-20ppm, 3.3Vdc, E/D Pad 1, Output Frequency 155.52MHz
To order an L143 with an output frequency of:
25 MHz = L143-025.0M
44.736 MHz = L143-044.736M
155.52 MHz = L143-155.52M
