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.

Vibration: Vibration per Mil Std 883E Method 2007.3 Test Condition A.

Shock: Mechanical Shock per Mil Std 883E Method 2002.4 Test Condition B.

Soldering Process; RoHS compliant lead free. See soldering profile on page 2.

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.
