Cable and backplane drivers top 6 Gbits/s

Adaptive equalizers come with 4, 8, and 12 channels

The M21030 cable and M21451 backplane 6.5-Gbit/s four-channel active adaptive equalizers are presented as yielding superior transmission quality, via an independent equalizer and driver with programmable output swing and de-emphasis, while consuming just 120 to 136 mW/channel. The devices' adaptive equalization is critical in applications where the transmission channel may be modified, such as when cables or blades are changed out and they feature small, 6 x 6-mm, QFN44 packages.

The eight-channel M21452 and twelve-channel M21453 backplane signal conditioners operate at 50 Mbits/s to 6.5 Gbits/s and need just 115 mW/channel. They provide high-quality backplane transmission at up to 40 in. across low-cost backplane materials such as FR-4. The two devices have programmable equalizers targeting environments where the nature of the transmission channel is well defined and the focus is on power and scalability.

All devices feature nonblocking switch matrices that can be used for redundancy. They support a wide range of protocols, including PCI Express, SAS, SATA, Infiniband, SONET and XAUI, and transparently pass out of band (OOB) signaling utilized in protocols such as SATA/SAS. All chips operate from -40° to 85°C. (M21030, $19.95; M21451, $12.95; , M21452 $23.95; $31.95, M21453 ea/prod qtysamples available now.)
