M21351/2/3 4.25 Gbps Backplane Signal Conditioners
> Product Overview
Mindspeed’s family of 4.25 Gbps backplane signal conditioners feature small form factor, low power devices that en-
able data transmission over long backplanes at speeds up to 4.25 Gbps. Mindspeed’s Amplif-Eye™ signal conditioning
technology enables transmission of 4.25 Gbps data over significant distances while traversing two backplane connec-
tors. These products are specifically designed to operate in environments that suffer from both loss and reflection.
Each 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 devices at speeds from
50 Mbps to 4.25 Gbps. The list of supported protocols includes: PCI Express, SATA, SAS, Infiniband, 2 x XAUI and Fibre
Channel. Mindspeed’s backplane signal conditioners are designed to recognize and transparently relay out-of-band
(OOB) signals for SATA/SAS and PCI Express. All devices include fully non-blocking switch matrices that allow for
simple switching as well as multi-cast functionality. Matrices can also be configured as failover switches. All devices
operate from -20° to +85°C. Devices can either be configured via a 2 wire interface or EPROM.
