Silicon Labs introduced the industry’s lowest jitter, lowest power and most frequency-flexible timing solution for high-speed networking equipment based on the Synchronous Ethernet (SyncE) standard. Offering an unmatched combination of any-frequency synthesis and industry-leading jitter performance (as low as 263 femtoseconds RMS), the new Si5328 precision clock multiplier and jitter attenuator addresses the need for ultra-low jitter physical layer reference clocks in Carrier Ethernet switches and routers. Eighty percent smaller and also 80 percent more power efficient than competing SyncE clocks, the Si5328 provides a best-in-class SyncE-compliant timing solution for edge routers, multi-service switches, wireless backhaul systems, DSLAMs and GPON/GEPON optical line termination (OLT) equipment. The telecom infrastructure market is rapidly transitioning from legacy SONET/SDH networks to higher-speed, more cost-effective Ethernet networks. A key enabling technology behind this network transition is Synchronous Ethernet, which is used to distribute accurate timing in Gigabit Ethernet (GbE), 10 GbE, 40 GbE, and 100 GbE Carrier Ethernet switches and routers. Every Carrier Ethernet switch and router requires a high-performance SyncE clock to provide wander filtering, distribute timing and provide a low-jitter Ethernet PHY reference clock. Silicon Labs has addressed this application need with the industry’s lowest jitter, most frequency-flexible SyncE timing solution optimized for Ethernet PHYs ranging from GbE to 100 GbE.
