Quad Channel 1G/10GBASE-KR to SFI Ethernet Repeater

Product Detail

VSC8256 is a quad 1G/10G serial-to-serial, protocol-agnostic repeater/retimer that integrates hardware-based host-side only 10GBASE-KR auto-negotiation and training in a small form factor, low-power FCBGA ideal for a wide array of board-level signal integrity applications. The quad channel VSC8256 device operates as a 10 GbE LAN, 10G WAN, 40 GbE (4 x 10G), as well as 1G legacy KR repeater with integrated cross-point switching enabling configurable line ordering for protection and broadcasting flexibility. Target applications for the VSC8256 device include switching, IP edge router connectivity, rack mount server access through backplane, fiber and copper cable connectivity, and standalone server access (in LAN on motherboard designs or separate network adapters). The VSC8256 device delivers excellent jitter attenuation with low power. It is also well-suited for SFP+ and QSFP+ based optical modules and direct attach copper cabling as well as challenging backplane interface applications. Its highly flexible clocking options support LAN and WAN operation using a single 156.25 MHz reference clock rate. Support for Synchronous Ethernet (SyncE) is also included.
