Digital crosspoint switch aids non-return-to-zero signalling

Analog Devices rolled out an asynchronous, protocol agnostic, digital crosspoint switch specifically for non-return-to-zero signalling. Featuring maximum data rates of 11.3Gbit/s per port, the ADN4612 switch provides various functions such as programmable input equalisation, loss-of-signal detection, programmable output swing, and output preemphasis/deemphasis.

The ADN4612 nonblocking switch core has 12 differential PECL-/CML-compatible inputs and 12 differential CML outputs. It uses 150 mW per channel at 2.5 V (outputs enabled). The ADN4612 also supports independent channel switching through the serial control interface and has low latency and very low channel-to-channel skew. Manufactured in an 88-lead LFCSP package, the switch operates from ?40 ℃ to +85 ℃. It is suitable for fibre optic network switching, 10GbE over backplane 10GBASE-KR 802.3ap designs, XLAUI/CAUI (802.3ba), SONET OC-192 / STM-64x and for 1×, 2×, 4×, 8×, and 10× Fibre Channel.
