10 GbE Line Card or NIC SUPERIOR EDC AT MULTIPLE RATES XAUI Serial 10 GbE The VSC8487-15 and VSC8488-15 devices integrate Vitesse’s Interface Interface SFP+/XFP world-class electronic dispersion compensation (EDC) performance 4 across multiple data rates and applications including 10.3 Gbps Dual 10 GbE 4 Ethernet (GbE), 9.95 Gbps WAN traffic, and 10.5 Gbps SAN traffic. MAC/NIC VSC8488-15 The devices also meet the SFP+ SR/LR/LRM host requirements in SFP+/XFP accordance with the SFF8431 specifications.

The VSC8487-15 and VSC8488-15 devices compensate for optical impairments in SFP+ QSFP+ applications, along with degradations of the PCB, while providing wide system margin for SR and LR applications. Switch Module

FULLY KR-COMPLIANT 4 The VSC8487-15 and VSC8488-15 devices provide full KR support, XAUI VSC8487-15 Switch including KR state machine, for autonegotiation and link optimization. Serial XAUI The transmit path incorporates a multitap output driver to provide Interface Interface 10GBASE-KR flexibility to meet the demanding 10GBASE-KR (IEEE 802.3ap) Tx Backplane output launch requirements.

EXTENSIVE FEATURES A complete suite of BIST functionality includes line and client loopbacks along with pattern generation and error detection. Highly flexible clocking options support LAN and WAN operation using single or multiple, 1/64 or 1/66 REFCLK rate inputs, along with seamless Synchronous Ethernet support. The VSC8487-15 and VSC8488-15 devices include a failover switching capability for protection routing, along with selectable lane ordering.
