The Connor-Winfield PB223 series clocks are an LVPECL output, fixed frequency, crystal-controlled oscillator (XO) designed for applications requiring tight frequency stability, wide temperature range, and very low jitter. Operating at a 3.3 V supply voltage, the PB223 series provides LVPECL differential outputs with enable / disable function. The surface mount 5 mm x 7 mm package is designed for high-density mounting and is optimum for mass production.

The PB223 series clocks exhibit ultra-low jitter performance with a frequency stability of ±20 ppm over the industrial temp range of -40°C to 85°C. Designed with a high frequency fundamental mode crystal, this series offers excellent phase noise performance.
