Interlaken-PHY (ILKN-PHY)

StreamDSP’s Interlaken-PHY (ILKN-PHY) IP core provides a lightweight, high-bandwidth FPGA interconnect solution based on the Interlaken framing layer — without the complexity of the full Interlaken protocol stack. Supporting any transceiver line rate up to 115 Gbps, multi-lane channel bonding, and all major FPGA vendors from Xilinx, Intel, Lattice, and Microsemi, it’s the ideal choice for engineers who need a scalable, low-overhead chip-to-chip link with a common interface across device families. Ships with reference designs and a complete simulation testbench.

Features of the StreamDSP Interlaken-PHY IP Core:

  • Channel bonding supported for any number of physical lanes
  • Any serial line rate supported by the FPGA transceiver can be used
  • Self-synchronizing links and automatic link resynchronization
  • Per-lane CRC32 for data integrity and diagnostics
  • Superb DC balancing for maximum link stability
  • Over 95% bandwidth efficient

FPGA Device Support

In addition to the devices listed above, support for any transceiver based FPGA from Intel (previously Altera), Microsemi, or Xilinx can be added in as little as 3-5 days with a valid user request.

StreamDSP’s multiple FPGA vendor support model provides customers extra flexibility and a low-overhead, high-bandwidth, SCALABLE data communication link between Altera, Intel, Microsemi and Xilinx FPGAs with a common user interface. The Interlaken-PHY IP core allows any number of channels to be bonded together for ultimate bandwidth flexibility. The IP can currently support any transceiver rate up to 32 Gbps, and a new development effort is underway to address link speeds up to 110+ Gbps in the newest FPGA devices. The Interlaken-PHY IP is designed to easily close timing even at the fastest transceiver rates and has an identical user interface for every FPGA family to ensure easy integration and design migration between families.

StreamDSP is committed to strong customer support, and will make every effort to ensure a successful IP integration. The FPGA IP core delivery includes a detailed User Guide, as well as “ready to run” demonstration designs for popular and easily available development boards. The demonstration designs each use a common data pattern generator and verifier circuit to allow any combination of development boards to be connected together to demonstrate error free communications as well as compatibility between Altera, Intel, Microsemi and Xilinx FPGAs. In addition to the demonstration designs, a complete self-verifying simulation testbench is provided that exercises the Interlaken-PHY IP Core in a stand-alone configuration.
