LatticeSC SFI-5 Evaluation Board

This evaluation board provides a functional platform for development and rapid prototyping of applications that incorporate high-performance SFI-5 interfaces. It can also be used to verify compliance to the SFI-5 standard, as it interoperates with the LatticeSC SERDES channels capable of operating at data rates between 600 Mbps and 3.125 Gbps.

The evaluation board includes provisioning to connect high-speed SERDES channels via SMA connectors to test and measurement equipment. The board is manufactured using standard FR4 dielectric and through-hole vias. The nominal impedance is 50-ohm for single-ended traces and 100-ohm for differential traces. The board has several debugging and analyzing features for complete evaluation of the LatticeSC device.

  • ispVM to download your program to the LatticeSC or on-board Flash memory devices

SFI-5 Standard and Lattice Intellectual Property (IP) Core

The Lattice SFI-5 Intellectual Property (IP) core enables user instantiation of an OIF-compliant SERDES Framer Interface Level 5 (SFI-5) core in LatticeSC/M Field Programmable Gate Arrays (FPGAs). The SFI-5 defines a communications interface for a 40 Gbps optical link which typically consists of a Framer, FEC (Forward Error Correction) Processor, and SERDES. The purpose of the SFI-5 interface is to transmit data across multiple channels in parallel, where channels may incur different skews between the transmitter and receivers. The SFI-5 receiver delays the data received on all of the channels to match that channel which incurred the longest delay. This removes any skew variation between the channels.
