Mindspeed’s family of 8.5 Gbps backplane signal conditioners feature small form factor, low power devices that enable

data transmission over long backplanes at speeds up to 8.5 Gbps. Mindspeed’s Amplif-Eye™ signal conditioning tech-

nology enables transmission of 8.5 Gbps data over significant distances while traversing two backplane connectors.

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 100

Mbps to 8.5 Gbps. The list of supported protocols includes: PCI Express, SATA, SAS, Infiniband, 2 x XAUI and 8 Gbps 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. M21483 matrix can also be configured as a failover/redundancy switch.

Both devices operate from -20° to +85°C. Devices can either be configured via a 2 wire interface or EPROM.
