VSC8664EV

® PRODUCT BRIEF VSC8664 Quad Port 10/100/1000BASE-T PHY and 100BASE-FX/1000BASE-X SerDes with Recovered Clock Outputs The industry’s first PHY with dual recovered clock outputs delivers carrier-quality Synchronous Ethernet Helping OEMs to capitalize on the cost reduction and optimization of Synchronous Ethernet, the VSC8664 addresses the challenges in providing fully traceable timing across TDM backhaul links, cellular base stations, and other Synchronous Ethernet 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. APPLICATIONS • Copper and fiber-based synchronous Ethernet systems • SGMII-to-SFP designs • Multiport, SGMII-based Gigabit Ethernet (GbE) designs LOW POWER • Low power consumption with three power savings modes • ActiPHY™ power management system with built-in intelligence and saving modes Carrier-Quality Synchronous Ethernet Meeting the carrier demands for redundancy, the VSC8664 features dual recovered clocks to enable a primary and secondary timing reference. Programmable clock squelch control is included to inhibit undesirable clocks from propagating and to help prevent timing loops. VSC8664 is the first GbE PHY to provide clock recovery in combination with an SGMII interface, making layouts simpler than RGMII/GMII solutions. Also featured is a fast link failure indication that can indicate the onset of a link failure in less than 1 ms, a critical feature for support of synchronization timing. 1 2 Recovered Clock Output RJ-45 4 4 VSC8664 Synchronous Ethernet PLL SGMII 4 SFP Gigabit Ethernet Switch / MAC CPU Highly Integrated, Cost-Effective Deployment VSC8664 helps to lower the component count without sacrificing capabilities or utility, resulting in more cost-effective production and deployment. Its patented, low electromagnetic interference line driver and integrated line side termination resistors conserve both power and printed circuit board space. With an integrated I2C multiplexer to control SFPs or power-over-Ethernet modules, VSC8664 also eliminates the need for an external two-wire serial device. 1 GbE Line Card Vitesse's mixed signal and digital signal processing (DSP) architecture yield robust performance, supporting both full and half duplex 10BASE-T, 100BASE-TX, and 1000BASE-T over >140 meters of CAT-5, unshielded twisted pair cable, with industry leading tolerance to NEXT, FEXT, Echo, and system noise. With dual, high-performance 1.25 Gbps SerDes, VSC8664 maximizes receive jitter tolerance and minimizes transmit jitter in comparison to single SerDes architectures. www.vitesse.com Making next-generation networks a reality. VSC8664 Wide Range of Support Flexibility • Compliant with IEEE 802.3 (10BASE-T, 100BASE-TX, 1000BASE-T, 100BASE-FX, and 1000BASE-X) specifications • Support for 802.3ah unidirectional transport for 100BASE-FX and 1000BASE-X fiber media • Support for >16 kB jumbo frames in all speeds with programmable synchronization FIFOs • Supports Cisco SGMII v1.7 and 1000BASE-X MACs, IEEE 1149.1 JTAG boundary scan, and IEEE 1149.6 AC-JTAG • Integrated quad I2C multiplexer to control SFPs or PoE modules, eliminating the need for an external two-wire serial device for the control and status of SFP or PoE modules • VeriPHY® cable diagnostics suite provides extensive network cable information such as cable length, termination status, and open/short fault location • Extensive test features (including near end, far end, and connector loopback, and Ethernet packet generator with CRC error counter) to decrease timeto-market Synchronous Ethernet Advanced SerDes • Recovered clock output support for G.8261 and IEEE-1588 synchronous Ethernet applications, including programmable squelch control • Patent-pending, fast link fail indication (
