QSFP+ Compliance Kit

Open Live Script

Test the channel design of a host board for compliance to the QSFP+ specification.

A QSFP+ link is made up of four SFP+ channels that are synchronized within the receiving module to support an aggregate 40 Gb/s link.

This kit is designed for compliance of the host board only. Module compliance is not currently supported in this kit. The kit includes IBIS-AMI TX and RX models for reference and compliance testing. Pre-layout and post-layout schematic sheets are provided. Package models are included only for post-layout reference IBIS-AMI models. These package models contain the QSFP+ connector, HCB (host compliance board), MCB, and SMA connector S-parameters. You can insert a channel design and test for compliance as specified in the QSFP+ specification (SFF-8431 for SerDes channel).

Open QSFP+ Kit

Open the QSFP+ kit in the Serial Link Designer app using the openSignalIntegrityKit function.

Kit Overview

  • Project Name: QSFP_Plus

  • Interface Name: QSFP_Plus

  • Target Operating Frequency: 11.1 Gb/s (UI = 90.009 ps)

The QSFP+ kit defines three schematic sets.

  • Pre_Layout_Reference_Schematics – Used for Pre-Layout testing of channel

  • Post_Layout_Reference_Schematics – Used for reference sheets when doing Post-Layout

  • All_Project_Schematics – Set of all project Schematics
