1.8V LVMOS
Clock Oscillator
Description:
The Connor-Winfield 51x1 and 52x1 Series
Surface Mount LVCMOS, Fixed Frequency
Crystal Controlled Oscillator (XO) are designed
for applications requiring tight frequency
stability, wide temperature range and low jitter.
Operating at 1.8V supply voltage, the 5xxx.
Provides a LVCMOS Output with a Tri-state
enable / disable function. The surface mount
package is designed for high-density mounting
and is optimum for mass production.

Notes:
1. Includes calibration @ 25°C, frequency stability vs. change in temperature, supply voltage and load variations, shock and
vibration and 20 years aging.
2. When the oscillator is disabled the output is at high impedance. Output is enabled with no connection on E/D pad.
3. The internal oscillator circuit continues to run when the output is disabled.
