M21452

6.5 Gbps Eight-Channel Backplane Equalizer and Driver with 8x8 Crosspoint Switch

Overview

Description

Mindspeed's M21452 eight channel 6.5 Gbps backplane signal conditioner features a small form factor, low power device that enables data transmission over long backplanes at speeds up to 6.5 Gbps. Mindspeed's Amplif-Eye™ signal conditioning technology enables transmission of 6.5 Gbps data to distances up to one meter while also traversing two backplane connectors. The M21452 is specifically designed to operate in environments that suffer from both loss and reflection. The device channel features an independent equalizer and driver with programmable output swing and de-emphasis to maximize power efficiency. Virtually any digital protocol can be transmitted through the device at speeds from 50 Mbps to 6.5 Gbps. The list of supported protocols includes: PCI Express, SATA, SAS, Infiniband, 2 x XAUI and Fibre Channel. Mindspeed's M21452 backplane signal conditioner is designed to recognize and transparently relay out-of-band (OOB) signals for SATA/SAS and PCI Express. The device includes fully non-blocking switch matrices that allow for simple switching as well as multi-cast functionality. Matrices can also be configured as failover switches. The devices operate from -40° to +85°C.
