"The VSC8664 is the industry's first PHY with dual recovered clock outputs delivers carrier-quality Synchronous Ethernet (SyncE). Helping OEMs to capitalize on the cost reduction and optimization of SyncE, the VSC8664 addresses the challenges in providing fully traceable timing across TDM backhaul links, cellular base stations, and other SyncE applications. With dual recovered clock outputs, the VSC8664 meets and goes beyond the requirements of the ITU-T Recommendation G.8261/Y.1361. Supporting four copper/fiber ports and SGMII MAC interfaces, the VSC8664 includes a highly integrated feature set to ensure low-cost, rapid deployment."
