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.

Notes:
1. All output frequencies may not be available, please contact the factory with your output frequency requirements.
2. Includes calibration @ 25°C, frequency stability vs. change in temperature, supply voltage and load variations, shock and vibration and 20 years aging.
3. When the oscillator is disabled the outputs are at high impedance. Outputs are enabled with no connection on E/D pad 1.
4. Vod measured with a 100 ohm resistor between the true output and the complementary output.
5. Duty cycle measured at 50% of output voltage swing.
