First DisplayPort 2.0 Video Analyzer and Generator

16 April 2020 – Teledyne LeCroy announced the availability of the quantumdata M42d Video Analyzer and Generator - the industry’s first DisplayPort 2.0 protocol test instrument. The M42d system supports both Source and Sink testing at the new data rates and line coding, as well as enhanced capabilities like LTTPR emulation and Panel Replay.

The DisplayPort 2.0 standard provides for data rates up to 20Gb/s per lane for an overall aggregate bandwidth of 80Gb/s, going well beyond the DisplayPort 1.4 standard’s aggregate rate of 32.4GB/s. These data rates support high screen resolutions of up to 16k with a 60 Hz refresh rate, and as such are perfect for applications like AR/VR and gaming. Designers and test engineers testing their products to ensure interoperability with other devices will benefit from the capabilities of a test solution like the quantumdata M42d Video Analyzer and Generator.

Teledyne LeCroy’s quantumdata M42d system supports both Source and Sink testing at the new data rates and line coding, as well as enhanced capabilities like LTTPR emulation and Panel Replay. The Capture Analyzer functionality provides deep visibility into the Main Link. And the Aux Channel Analyzer logs the Aux Channel transactions. All compliance test suites for DisplayPort 1.4 data rates are available now, and DisplayPort 2.0 Link Layer compliance tests will be added as they are defined by the committee. The M42d incorporates built-in passive probing based on Teledyne’s LeCroy state-of-art T.A.P.4. “Adding the passive probing option allows for non-intrusive monitoring of the Aux Channel and Main Link between devices and is especially valuable at the higher data rates offered by DisplayPort 2.0,” said Neal Kendall, Product Manager for Teledyne LeCroy’s Video products.

“As consumer electronic products, ranging from desktop PCs and displays to mobile and wearable devices increasingly incorporate the DisplayPort digital interface to drive higher video resolutions and frame rates, it is essential for the ecosystem to have test tools for both specification and product development, as well as product compliance testing. We depend on efforts of VESA® member companies like Teledyne LeCroy to provide comprehensive test solutions for DisplayPort 2.0 silicon and devices,” said Bill Lempesis, executive director of the Video Electronics Standards Association (VESA), which develops and administers the DisplayPort standard and compliance logo program.
