The Xilinx SPI-3 core provides a fully compliant Packet-Over-SONET/SDH (POS) solution, which can be quickly integrated into networking systems.
The Xilinx® SPI-3 Link Layer core provides a fully compliant Packet over SONET (POS) solution, which can be quickly integrated into networking systems. Through user-configurable options, such as interface width, internal Tx and Rx FIFOs, and byte or packet-level transfers, the SPI-3 core provides design flexibility while seamlessly interoperating with industry leading Application Specific Standard Products (ASSPs) to maximize the data transfer bandwidth. The Xilinx SPI-3 core is fully compliant with the Optical Internetworking Forums System Packet Interface Level 3 (SPI-3) standard (OIF-SPI3-01.0), as well as the SATURN® Development Groups POS-PHY Level 3 (PL3) interface specification.
关键特性
- Fully compliant with OIF-SPI3-01.0 System Packet Interface Level-3 (SPI-3) standard.
- Aggregate bandwidth in excess of 2.5-Gbps supporting OC-48 line rates and beyond.
- Configurable interface data widths: 32-bit, 16-bit, and 8-bit.
- Byte-Level and Packet-Level Transmit flow control options.
- Supports 1 to 256 addressable channels.
- Transmit and Receive cores are delivered as independent solutions for flexible implementation.
- Fully parameterizable internal FIFO using BlockRAM, Distributed Memory, or built-in FIFO primitives.
- Configurable Transmit Calendar implementation.
- LocalLink User Interface allows easy interconnection.
The SPI-3 Link Layer core connects to Physical (PHY) layer devices within networking applications. The core communicates between devices using the SPI-3 interface standard at up to 5.6-Gbps, enabling OC-48 POS, ATM, and Gb Ethernet applications. The Xilinx SPI-3 Link layer core has been verified in hardware to interoperate with PMC-Sierra PM5381, and PM3386 PHY devices.
