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
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 confi gurable line ordering for
protection and broadcasting fl exibility.
Target applications for the VSC8256 device include switching, IP edge
router connectivity, rack mount server access through backplane, fi ber
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 fl exible clocking options support LAN and WAN operation
using a single 156.25 MHz reference clock rate. Support for
Synchronous Ethernet (SyncE) is also included.
