Ultra-low phase noise from LVPECL clock oscillators

August 14, 2015 // By Graham Prophet
Crystek’s CCPD-575 is an ultra-low phase noise LVPECL oscillator providing a -162 dBc/Hz noise floor. Compact and powerful, the CCPD-575 offers leading phase noise for an LVPECL oscillator – at least 15 dB lower phase noise than most LVPECL oscillators on the market today.

Close-in phase noise is -90 dBc/Hz for the 100 MHz variant. This overall ultra-low phase noise translates to a typical phase jitter of 85 fsec RMS (12 kHz to 20 MHz). The extremely low phase noise performance is very useful in applications such as: Digital Video, SONET/SDH/DWDM, Storage Area Networks, Broadband Access, Ethernet, and Gigabit Ethernet.
