DisplayPort 1.4a IP Core

Description

DisplayPort heralds a new alternative in video connectivity. Designed to enable low cost direct drive monitors and backed by industry leaders (Intel, DELL, Apple etc) DisplayPort is not hindered by license and royalty fees.

The Bitec DisplayPort IP core enables DTV manufacturers to rapidly develop and deliver displays offering a superior viewing experience within ever-shrinking product lifecycles.

The Bitec DisplayPort IP core accepts 1,2 or 4 lanes at either 1.62, 2.7, 5.4 or 8.1 Gbps link rate (includes eDP additional rates), in compliance with the DisplayPort 1.4 specification.

Video data is input to the core Transmitter as parallel data with H-sync, V-sync and Data Enable signals. Audio and secondary data streams are also supported and available for transport.

The core Receiver can output received video data on a stream interface for convenient interfacing to downstream logic. Audio and all Secondary Data are available in parallel format on their respective outputs. Both Receiver and Transmitter can use optional AUX debug ports for run-time AUX message log and monitoring.

Multi-Stream (MST) applications

The Bitec DisplayPort IP Core Receiver supports Multi-Stream, a powerful DisplayPort v.1.4a feature allowing to transfer video and audio content for more than one display using only a single cable. For instance, four Full-HD streams (1920 x 1080p @ 60 Hz) can be delivered to the Receiver using Multi-Stream or a single 4K@60 stream (3840 x 2160 @ 60 Hz) using either Multi- or Single-Stream mode.

Clock Recovery support

A Clock Recovery block is available for the Bitec DisplayPort IP Core Receiver when the application requires DisplayPort received video data to be output together with the synthesized original pixel clock. This feature is useful, for instance, for outputting HDMI and analog video without using a frame buffer. The clock recovery feature is licensed separately.

Intel Arria 10 GX DisplayPort Evaluation kit

An evaluation kit is available to allow application development using the Bitec DisplayPort IP Core. The kit includes an Arria 10 GX development kit (Stratix V available on request), a Bitec DisplayPort FMC daughtercard and a DisplayPort cable. An Opencore evaluation Bitec DisplayPort IP Core is requried. The Opencore evaluation gives full functionality of the core under the standard Opencore terms. The Bitec DisplayPort Daughter Card allows easy interfacing to standard source and sink devices . Bitec also offer a tailoring service for bespoke designs. Contact Bitec for more details.
