VSC8256EV

VSC8256 Quad Channel 1G/10GBASE-KR to SFI Ethernet Repeater 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. Highlights 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. • Data rates supported include 10.3125 Gbps LAN mode, 9.95328 Gbps WAN mode, and 1.25 Gbps mode 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. 10 GbE 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. 10 GbE Line Card or NIC • Standards supported include IEEE 802.3ae, IEEE 802.3ap, SFF-8431, ITU-T G.8261, and ITU-T G.8262 • Signal conditioner mode supports protocolagnostic data rates • Support for SFP+/QSFP+ line modules and 10GBASE-KR backplanes between 1.25 Gbps and 10.3125 Gbps (including host-side auto-negotiation and training) Applications • Multi-port serial-to-serial signal conditioning • 10GBASE-KR-compliant backplane transceivers • Multi-port XFI/KR to SFI/SFP+ 10 GbE switch cards, router cards, and network adapters Switch Modules Module Quad 10 GbE MAC/NIC Module VSC8256 10 G Switch VSC8256 Module Module 4 × 10G 4 × 10G 4 × 1G 10GBASE-KR Backplane 4 x 10G 4 x 1G 4 x 10G 4 x 1G Microsemi makes no warranty, representation, or guarantee regarding the information contained herein or the suitability of its products and services for any particular purpose, nor does Microsemi assume any liability whatsoever arising out of the application or use of any product or circuit.
