Connect the DisplayPort FMC card to the J14 FMC connector on the PolarFire Video kit.

Introduction

Microchip’s DisplayPort FPGA Mezzanine Card (FMC) Daughter Card (VIDEO-DC-DP) is a dedicated platform for evaluating and testing the comprehensive IP for transmit and receive, and a ready-to-run demonstration design.

The daughter card works with the PolarFire® Video and Imaging Kit (MPF300-VIDEO-KIT-NS) featuring the PolarFire® 300KLE FPGA device.
The PolarFire and PolarFire SoC FPGAs support DisplayPort v1.4 with a transceiver-based IP that can attain speeds up to 8.1 Gbps per lane in 1, 2, or 4-lane configurations.

This solution is part of Microchip’s extensive Smart Embedded Vision Portfolio of IPs and solutions.
The IP is license-locked in clear text RTL. It supports the generation of encrypted RTL for a Verilog version with no license.

The IP and the hardware must be purchased separately as where applicable.
The following table shows the contents of the DisplayPort FMC daughter card.

PolarFire Display Port Rx Solution with Video Demo

This section demonstrates the usage and running of the imaging and video demo using the PolarFire Video kit, with a Host PC and a DisplayPort Rx.

Setting up the Hardware for the PolarFire DisplayPort Rx

To set up the hardware for the PolarFire DisplayPort Rx, perform the following steps:

To connect the DisplayPort FMC card, attach the DisplayPort FMC card to the J14 FMC connector on the PolarFire Video kit.
To connect the host laptop, use a DisplayPort cable to connect the laptop’s DisplayPort output to the DisplayPort Rx interface on the DisplayPort FMC card.
To connect the HDMI output, connect an HDMI cable from the monitor to the J1 (HDMI TX) port on the PolarFire Video kit.
To establish host PC communication, use a USB mini cable to connect the host PC to the PolarFire Video kit through the J12 connector.
To power the board, plug the 12V power supply cable into the J20 onboard DC jack of the video kit.
Ensure the jumper settings on the video kit are configured as required for the demo.
To power on the Board, slide the SW4 switch to the ON position.
