Lattice's Quad GbE Over SONET/SDH Bridge is a hard IP Core implemented in two Lattice ORCA4E06 devices that act as a bridge between two Intel Dual-Port GbE MAC devices (part number IXF1002) and an Agere System's SONET Framer device (part number TADM042G5v2). External 64Mb DRAM is also used as part of the system for buffering data and flow control purposes. The 9-page Data Sheet provides a brief description of the IP Core, its signals, and the system solution. Please consult the Lattice factory for further information.
