The ORT82G5 offers a clockless high-speed interface for interdevice communication on a board or across a backplane. The built-in clock recovery of the ORT82G5 allows for higher system performance, easier-to-design clock domains in a multiboard system, and fewer signals on the backplane. Network designers will benefit from the backplane transceiver as a network termination device.The first version of the device supports 8b/10b encoding/decoding and link state machines for Ethernet, fibre-channel, and InfiniBandTM. Version II adds SONET data scrambling/descrambling, streamlined SONET framing, transport overhead handling, plus the programmable logic to terminate the network into proprietary systems. For non-SONET applications, all SONET functionality is hidden from the user and no prior networking knowledge is required. Version II adds decimation and interpolation for connections at 622 Mbits/s rates.
