The 10 Gigabit MAC (per IEEE* 802.3ae) handles frame encapsulation, verification, 10GbE flow control, and Remote Monitoring/ Simple Network Management Protocol (RMON/ SNMP) statistics management. The IXF18103 MAC also handles the IEEE* 802.3ae Physical Coding Sub-layer (PCS) and WAN Interface Sub-layer (WIS) functions of the 10 Gigabit Ethernet standard. The PCS hardware handles the 64B/66B encoding/decoding to provide the transition density and balance of the 10.3125 Gbps stream. The WAN Interface Sub-layer provides the rate matching mechanism for 9.953 Gbps rate transport, as well as the STS-192c/STM-64c framing structure used in WAN PHY applications.
The system interface supports the industry-standard System Parallel Interface Level 4 Phase 2 (SPI-4.2). This interface is 16 bits wide with 622 Mbps-800 Mbps Double Data Rate (DDR) clocking. The SPI-4.2 interface is Low Voltage Differential Signaling (LVDS).
On the line side, the IXF18103 MAC supports the IEEE* 802.3ae XSBI interfaces. The 16 bit LVDS interface can operate at 622 Mbps to support the 10 GbE WAN rate of 9.953 Gbps, and at 644 Mbps to support the 10GbE LAN rate of 10.3125 Gbps.
The IXF18103 MAC also supports an integrated Pseudo Random Bit Sequence (PRBS) packet generator/analyzer for the PCS and WIS blocks per IEEE* 802.3ae clause 49 and 50. Line remote, line local, system remote, and system local loop backs are also supported, as well as Synchronous Payload Envelope (SPE) payload test loop back for general development functionality test and debug.
Cortina's IXF1810x family of 10 Gigabit framer devices provide the broadest support for 10 Gbps solutions. The protocols supported are STS-192c POS, 10 Gigabit Ethernet WAN, 10 Gigabit Ethernet LAN, and GFP framing. The table below summarizes the high-level feature set: |

All these devices are pin-, footprint-, and register set-compatible. This allows customers to design one line card for multiple applications, providing cost savings over a single line card with other unsupported features.
The IXF18103 MAC is designed to provide a single chip solution for all 10 GbE LAN or WAN Physical Layer and MAC requirements for metro and core networks.
