• Compliance with the PCIe Base and CEM 1.0a specifications:
• x1 or x4 lane link interface (auto negotiated with system) at 2.5 Gb/s
• Support for VC0 (1 Virtual Channel) and TC0 (1 Traffic Class)
• Configuration, I/O, memory, read/write, completion, and message support
• Support for 64-bit addressing
• ECRC for all transmitted PCIe data packets
• Link CRC on all PCIe packets and message information
• Support for large payload size (2048 bytes for read/write)
• Support for large read request size (4096 bytes)
• Internal high-speed static RAM (SRAM)
• Error correcting code (ECC) protection of local memory, including single-bit correction and
double-bit protection
• Small form factor (SFF) multimode optic with LC connector
