Quad SPI-3 to SPI-4 PHY Layer Bridge


Newsletter Subscription

The Quad SPI-3 to SPI-4 Bridge Intellectual Property (IP) Core targets the programmable array section of the ORCA ORSPI4 FPSC and provides the PHY Layer bridging function between one to four SPI-3 links and a SPI-4 link.

    Features

    • Complete Quad SPI-3 to SPI-4 PHY Layer Bridge Solution Based on the ORCA ORSPI4 FPSC
    • IP Targeted to the ORSPI4 Programmable Array Section Implements Functionality Conforming to OIF-SPI3-01.0, Including:
      • Up to four full featured SPI-3 PHY Interfaces
      • Up to eight ports supported per Interface
      • Parameterizable FIFO size selection
      • Parameterizable Byte or Packet Mode selection
      • Configurable through the MicroProcessor Interface (MPI) ORCA 4 System Bus
      • Programmable parity type on SPI-3 bus
    • SPI-4 Functionality Supported by the Embedded Section of the ORSPI4, Including:
      • Standard 10 Gbps physical to link layer interface
      • Support for "static" and "dynamic" alignment at the receive interface
      • Single-link and multi-link operation
      • SPI-4.2 transmit data protocol support logic
      • Embedded calender-based sequence port polling mechanism and bandwidth allocation for 256 ports
