The XS4 (XAUI SPI-4.2) Bridge from MorethanIP provides a cost effective and integrated solution to bridge an SPI4.2 interface to a XAUI interface. The XS4 Bridge provides a generic solution to meet multiple design requirements such as device bridging (e.g., NPU to Ethernet Switch), serial backplane applications, and Packet over SONET/SDH (POS) or Ethernet over SONET/SDH (EOS) applications. The MAC also implements a HiGig mode, which can used to interface with broadcom switches. Features include:
- MAC layer and reconciliation sub-layer implementation compliant with IEEE 802.3ae specification with HiGig Mode to interface broadcom switch devices
- Bridge can be delivered with a XGMII or a XAUI interface
- Large embedded FIFO buffers with automatic flow control with pause frame generation from programmable congestion thresholds
- SPI-4.2 interface compliant with PMC-Sierra PMC-1991635 specification document with 16-bit LVDS DDR operating at rates of 800 Mbps per pin
- Complete set of error event counters providing application management and application monitoring accessible via host processor interface
