HDMI 2.2 pushes the ecosystem from “it works” to “it works at 96Gbps”, which changes what engineers need to validate: Fixed Rate Link (FRL) behavior, Forward Error Correction (FEC), link training, and the way metadata and audio ride alongside high-rate video. In this interview, Teledyne LeCroy’s quantumdata team frames their role as the plumbing behind the logos—tools chip vendors and device makers use to debug, pre-test, and get ready for formal certification. https://www.teledynelecroy.com/protocolanalyzer/quantumdata-m42h
The centerpiece is the quantumdata M42h, a compact HDMI generator + protocol analyzer built for HDMI 2.2 FRL rates up to 96Gbps (24Gbps per lane), with visibility into FRL packetization (superblocks / character blocks), control data, InfoFrames, and captured error conditions. Filmed at CES Las Vegas 2026, the demo lands on a key point: test gear can be available ahead of the final compliance program, so silicon teams can iterate while the certification details get locked.
A practical theme is emulation. When you can’t buy an HDMI 2.2 display or source off the shelf, a box that can impersonate a sink or a source becomes the reference endpoint, letting teams validate interoperability before TVs, consoles, and GPUs ship. The loopback workflow shown—generate a defined stream, feed it back, then analyze what returns—turns “the picture looks odd” into timestamped protocol events you can debug in a lab.
They also point to a more portable, battery-powered tester with a built-in screen for AV integrators who need on-site verification—EDID behavior, HDCP handshakes, and signal continuity—without hauling a full bench setup. Rollout expectations stay grounded: Ultra96-class cables tend to arrive first, while sources and sinks follow once compliance specs and logos are finalized, with the interview estimating late 2026 into early 2027 for broader shelf availability, depending on real-world timing.
Teledyne LeCroy positions this as one slice of a broader protocol-test stack spanning HDMI, DisplayPort, USB, PCI Express, Ethernet, Wi-Fi, Bluetooth, and MIPI. The takeaway is that “new standard” is mostly a test problem—repeatable stimulus, deep capture of the right protocol layers, and turning edge-case failures into actionable debug data for real hardware.
