SY89610L
77.75MHz to 694MHz Jitter Attenuator and Low Phase Noise Frequency Synthesizer
General Description
The SY89610L is a 3.3V, fully differential jitter attenuator and frequency synthesizer that accepts a noise clock between 19.44MHz and 694MHz, depending on I/O frequency selection. The output provides an ultra-low jitter clock frequency between 77.75MHz and 694MHz covering SONET/SDH, Gigabit Ethernet, Fibre Channel, SAS, SATA, and many other communication standards. The output jitter of the SY89610L is typically 1psRMS. It has a 1kHz to 10kHz programmable loop bandwidth to accommodate different jitter attenuation applications and PLL requirements. The auto-tune circuit enables precision frequency calibration.
