The LatticeECP3 XAUI demo demonstrates the performance of the LatticeECP3 PCS in XAUI mode at 3.125 Gbps. The XAUI Demo Design is a quad-based XAUI generator/checker that transmits/checks XGMII data to/from a PCS quad. In turn, the PCS quad serializes the data in the transmit direction, and de-serializes it in the receive direction. For this demo the encoded serial data stream is looped-back externally via cables using the on-board SMA connectors. In this case, a backplane of variable length can be included in the serial path, or the Quad outputs can be connected to its inputs.
