Silicon Laboratories has released its Si5315 jitter-attenuating clock multiplier IC that meets or exceeds the performance, integration, frequency and jitter requirements for the 1G and 10G Synchronous Ethernet (SyncE) market.
The Si5315, the latest in Silicon Labs' any-rate precision clock family, is touted as the industry's only SyncE clock multiplier IC to support 10G line encoding rates (161.13 MHz) in addition to SONET/SDH and Ethernet frequencies.
The device requires no external phase-locked loop (PLL) components, dramatically simplifying line card design and frequency translation in carrier Ethernet switch routers, wireless backhaul, 3G/4G base stations, multi-service access platforms, passive optical networking, IP DSLAM and T1/E1 infrastructure.
Silicon Labs said the Si5315 provides the lowest jitter of any SyncE clock IC in the industry at less than 0.6 ps rms phase jitter, meeting the jitter requirements specified by ITU-T G.8262 and providing significant margin to Gigabit Ethernet (GbE) and 10 GbE PHY jitter requirements.
