Keysight Unveils New Automotive Testing Solution for Mobile Industry Processor Interface

Keysight-Technologies announced a new Automotive Serializer/Deserializer (SerDes) Receiver (Rx) conformance test solution to verify Mobile Industry Processor Interface (MIPI) A-PHY devices against specification requirements conformance test (CTS).

This solution was developed in collaboration with BitifEye Digital Test Solutions GMBH and Wilder Technologies, with the support of Valens Semiconductor.

Silicon vendors plan to implement MIPI A-PHY®, a long-range physical layer interface for automotive and other surround sensor applications, including cameras and in-car infotainment (IVI) displays. Manufacturers are continually improving vehicles with autonomous features and there is significant awareness that these features should improve safety conditions. Therefore, data collected by sensors and cameras must be transmitted accurately, precisely and quickly, from any silicon vendor.

Keysight’s Rx compliance test solution recreates a compliant transmitter that generates a controlled distorted (worst case) signal and analyzes the impact of the distortions on the receiver’s ability to correctly sample the transmitted data. It allows vehicle manufacturers and their suppliers, as well as automotive engineers and system integrators, to stress the receiver and validate its performance in the noisy and inherently harsh environment of a car.

BitifEye Digital Test Solutions GMBH offers test software that complements Keysight’s product portfolio of highly integrated and automated application-specific test systems. Keysight has partnered with BitifEye to provide the first solution capable of testing SerDes MIPI A-PHY automotive datalink receivers.
