Teledyne LeCroy presents its latest test and measurement equipment for high-speed digital interfaces, including MIPI and HDMI. Kimsey, a business development manager, details a versatile MIPI test tool that combines a generator, analyzer, C-PHY, and D-PHY into a single reconfigurable unit. This device is designed for testing MIPI CSI and DSI interfaces commonly found in battery-powered products like automotive systems and mobile phones. It utilizes S&P connectors for direct connection or interfacing via probes to capture and analyze signals on the bus.

HDMI® Technology is the foundation for the worldwide ecosystem of HDMI-connected devices; integrated with displays, set-top boxes, laptops, audio video receivers and other product types. Because of this global usage, manufacturers, resellers, integrators and consumers must be assured that their HDMI® products work seamlessly together and deliver the best possible performance by sourcing products from licensed HDMI Adopters or authorized resellers. For HDMI Cables, consumers can look for the official HDMI® Cable Certification Labels on packaging. Innovation continues with the latest HDMI 2.2 Specification that supports higher 96Gbps bandwidth and next-gen HDMI Fixed Rate Link technology to provide optimal audio and video for a wide range of device applications. Higher resolutions and refresh rates are supported, including up to 12K@120 and 16K@60. Additionally, more high-quality options are supported, including uncompressed full chroma formats such as 8K@60/4:4:4 and 4K@240/4:4:4 at 10-bit and 12-bit color.

Also featured is the 42H, a test instrument for the HDMI 2.2 specification. This unit supports the full 96 Gbit/s data rate required for 16K resolution video. It functions as both a signal generator and analyzer, providing comprehensive testing for the latest HDMI standard while maintaining backward compatibility with older versions down to HDMI 1.4, including TMDS signaling. The device is critical for manufacturers developing next-generation displays, sources, and cables capable of handling extreme resolutions.
The discussion highlights the role of Display Stream Compression (DSC) in the HDMI 2.1 and 2.2 specifications, which enables the transmission of 8K and 16K video by providing a visually lossless compression. The 42H tester fully supports the generation and analysis of these compressed streams, allowing developers to verify compliance and performance even before 16K source and sink devices are widely available on the market. This capability helps future-proof development and investment in test equipment.
Finally, the Quantum BDM21 is demonstrated as a functionality tester with a focus on debugging HDMI handshake issues. Its key feature is the Auxiliary Channel Analyzer (ACA), which captures and displays all communication on the auxiliary channel during events like a hot-plug detect. This allows engineers to trace the entire sequence, including EDID reads and other critical data exchanges, to quickly identify and resolve interoperability problems that frequently occur during the HDMI connection process.
This overview covers the practical application of these tools for validating compliance and ensuring robust performance in high-speed display and camera interfaces. The equipment enables developers to test everything from physical layer signal integrity to protocol-level handshaking for both established and emerging standards like HDMI 2.2.
