Overview
The Si535/536 devices are Skyworks Solutions latest ultra-low jitter crystal oscillators. The Si535/536 is finely tuned to perform at less than 200 fs (femto-second) RMS jitter across common Ethernet and Fibre Channel reference frequencies. Skyworks Solutions Si535/536 oscillators have three key features which allow them to stand out from the competition. They utilize Skyworks Solutions patented DSPLL® circuitry to provide a low jitter clock at high speed differential frequencies. These devices provide guaranteed low typical and maximum jitter and superior power supply noise rejection. Mixed-signal DSPLL technology allows Skyworks Solutions to supply oscillators at any output frequency. The Si535/Si536 devices allow for design flexibility featuring both 2.5 and 3.3 V with LVDS and LVPECL output formats, simplifying interfacing to a range of Ethernet switches, PHYs and FPGAs used in data center applications. The Si535/536 supports both pin 1 and pin 2 output enable (OE) options in an industry standard 5 mm x 7 mm package, enabling drop-in compatibility and simplifying second-sourcing to help facilitate winning new and existing oscillator socket designs. The Si535/536 lead times are short and predictable at only 2 to 4 weeks versus lead times of up to 8 weeks for the competition.
