Low Jitter

LVPECL

Clock Oscillator

Description:

The Connor-Winfield PBxxx series are

5.0x7.0mm Surface Mount, LVPECL output

logic, Fixed Frequency Crystal Controlled

Oscillator (XO) designed for applications

requiring tight frequency stability, wide

temperature range with very low jitter. Operating at

3.3V supply voltage, the PBxxx series provides LVPECL

Differential Outputs with enable / disable function. The

surface mount package is designed for high-density

mounting and is optimum for mass production.
