Crystek Corporation CCPD-575 Ultra-Low Phase Noise Clock Oscillators

Crystek Corporation CCPD-575 Ultra-Low Phase Noise Clock Oscillators are SMD, LVPECL oscillators with a typical noise floor at -162dBc/Hz in a 5mm x 7.5mm package. This is at least 15dB lower phase noise than most LVPECL oscillators on the market. Close-in phase noise is also excellent at -90dBc/Hz for the 100MHz variant. This overall ultra-low phase noise translates to a typical phase jitter of 65fs RMS (12kHz to 20MHz) at 156.250MHz.
