5x7mm Surface Mount
LVDS Clock Oscillator
Description:
The Connor-Winfield LMxxx - Series
are 5x7mm Surface Mount, LVDS, Fixed
Frequency Crystal Controlled Oscillator
(XO). The LMxxx - Series are designed for
applications requiring tight frequency stability,
wide temperature range, and low jitter. Operating
at 2.5 or 3.3 Vdc supply voltage, the LMxxx -
Series provides LVDS Differential Outputs with an
enable / disable function. The design utilizes PLL
multiplication to produce a high frequency output
from a low frequency fundamental crystal.
