Silicon Labs introduced a new family of crystal oscillators (XOs) that provide ultra-low jitter reference timing for 10G, 40G and 100G cloud computing and networking equipment. These new Si535 and Si536 XOs leverage Silicon Labs’ proven DSPLL® technology to provide unparalleled performance, stability and flexibility for 10/40G data center core/access switches, storage area networking equipment, security routers, enterprise switches/routers, and Carrier Ethernet switches and routers.
To support the burgeoning demand for cloud computing-based services, data center equipment is migrating to higher speed serial data transmission, often 10G or faster. In parallel, there is a significant trend to maximize energy efficiency by consolidating switching, storage and computing resources into fewer components. These trends have given rise to processors, Ethernet switch ICs and FPGAs with integrated high-speed serializer-deserializer (SerDes) technology that requires low-jitter timing references. Silicon Labs’ Si535/536 oscillators provide the ultra-low jitter and ±20 ppm stability required by state-of-the-art cloud computing and networking infrastructure equipment.
The Si535/536 XOs offer exceptional jitter performance of <200 femtoseconds (fs) RMS jitter (integrated from 10 kHz to 1 MHz) for common Ethernet and Fibre Channel reference frequencies. The Si535/536 oscillators support LVDS and LVPECL output formats at 2.5 V and 3.3 V and offer both ±20 ppm and 31.5 ppm total stability, simplifying interfacing to a wide variety of processors, switches, PHYs and FPGAs. When combined with Silicon Labs’ Si533xx differential clock buffers, the Si535/536 XOs provide low-jitter clock generation and distribution for SoCs requiring multiple high-performance reference clocks.
The Si535/536 oscillators use Silicon Labs’ patented DSPLL technology to provide a low-jitter clock at
high-speed differential frequencies.
