Mindspeed’s family of 5.5 Gbps backplane signal conditioners feature small form factor, low power devices that en-
able data transmission over long backplanes at speeds up to 5.5 Gbps. Mindspeed’s Amplif-Eye™ signal conditioning
technology enables transmission of 5.5 Gbps data over long distances while also 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. Random jitter is significantly reduced with an auto-rate detecting clock and data recov-
ery (CDR) block that can operate up to 5.5 Gbps for extremely low output jitter. Virtually any digital protocol can be
transmitted through the devices at speeds from 100 Mbps to 5.5 Gbps. The list of supported protocols includes: PCI
Express® (PCIe), SATA, SAS, Infiniband®, 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 PCIe. All devices include
fully non-blocking switch matrices that allow for simple switching as well as multi-cast functionality. M21363 matrix can
also be configured as a failover/redundancy switch. All devices operate from -20° to 90°C and can either be configured
via a 2 wire interface or EPROM.
