Silicon Labs, 250MHz Clock Oscillator, ±20ppm LVPECL, 6-Pin SMD 545AAA250M000BAG

The Si545 Ultra Series oscillator utilizes Silicon Laboratories’ advanced 4th generation DSPLL® technology to provide an ultra-low jitter, low phase noise clock at any output frequency. The device is factory-programmed to any frequency from 0.2 to 1500 MHz with <1 ppb resolution and maintains exceptionally low jitter for both integer and fractional frequencies across its operating range. The Si545 offers excellent reliability and frequency stability as well as guaranteed aging performance.
