Keysight Technologies Launches New Automotive Test Solution for Mobile Industry Processor Interfaces

Verify the Mobile Industry Processor Interface (MIPI) A-PHY® to enable large-scale interoperability according to compliance test specifications

Keysight Technologies, Inc. recently announced the launch of a new automotive serializer/deserializer (SerDes) receiver (Rx) compliance test solution to verify the Mobile Industry Processor Interface (MIPI) A-PHY devices according to the Compliance Test Specification (CTS) requirements. The solution was jointly developed by Keysight, BitifEye Digital Test Solutions GMBH and Wilder Technologies, and supported by Valens Semiconductor Ltd. (NYSE: VLN). Keysight provides advanced design and verification solutions designed to accelerate innovation and create a secure connected world.

Chip vendors are generally planning to adopt MIPI A-PHY®. This long-range physical layer interface is ideal for automotive and other surround sensor applications, such as cameras and in-vehicle infotainment (IVI) displays. Automakers are constantly improving autonomous driving features, and they also realize that these features should help improve the safety of the car. Therefore, any manufacturer's chip must be able to accurately and quickly transmit the data collected by sensors and cameras.

Keysight Technologies' Automotive SerDes Receiver Solution Supports MIPI A-PHY Testing Using Keysight M8195A AWG

Keysight's receiver compliance test solution re-architects a compliance transmitter that generates a controlled distortion signal (worst case) and analyzes how the distortion affects the receiver's ability to correctly sample the transmitted data. It enables automakers and their suppliers, as well as automotive engineers and system integrators, to stress test receivers and verify their performance in noisy and inherently harsh automotive environments.

"Keysight recognizes the growing need for next-generation high-speed digital interfaces for in-vehicle networks and our actions are critical at this time," said Thomas Goetzl, vice president and general manager of Keysight's Automotive and Energy Solutions group. "This new solution is our way of supporting the automotive industry's technology development and standardization efforts."

Keysight's receiver compliance test solution ensures the quality of digital transmissions by measuring the receiver's ability to recover data from impaired input signals. Key features of the solution include:

• A comprehensive test framework that can be used to determine the operating margin of the device under test (DUT).

• A custom test fixture that couples noise into the active link to stress test the receiver.

• Generate accurate and repeatable results using Keysight's arbitrary waveform generator (AWG) to generate a variety of complex random noise curves.

• Access predefined noise profiles.

• All relevant hardware, software and accessories are provided under one model, saving time and cost.

• Automatic reporting capabilities that generate detailed reports in HTML or PDF format, including margin analysis results.

The test software provided by BitifEye Digital Test Solutions GMBH complements Keysight's products to form a highly integrated, highly automated, application-specific test system. Keysight and BitifEye have collaborated to pioneer a solution that can test automotive SerDes MIPI A-PHY data link receivers.

"We are very pleased to collaborate with Keysight to provide the industry with a new approach to verifying MIPI A-PHY receivers," said Julien Henaut, COO of BitifEye Digital Test Solutions GMBH. "This test solution will benefit our customers by helping device manufacturers set the global standard for high-speed data transmission in vehicles through new in-vehicle networks, including both standardized and approved devices."
