Teledyne LeCroy has introduced the QPHY2-ASA compliance test software for the Automotive SerDes Alliance (ASA) Motion Link (ML) v1.1 specification, designed for in-vehicle network standards supporting data transfer in highly autonomous vehicles.
SerDes devices facilitate one-directional data transfer from sensors and cameras to in-vehicle processing units, enabling the creation of instruction sets for autonomous vehicle operation. The ASA ML v1.1 standard is one of several competing automotive SerDes standards, alongside MIPI’s A-PHY and Analog Device/OpenGMSL’s Gigabit Multimedia Serial Link (GMSLTM). Teledyne LeCroy participates in the standard-setting organizations for these technologies.
The QPHY2-ASA software, informed by Teledyne LeCroy’s involvement in ASA ML standards committees and plugfests, addresses testing requirements as finalized by ASA member companies. It is available early in the ASA ML v1.1 adoption phase and is compatible with Teledyne LeCroy’s WaveMaster 8000HD Series oscilloscopes, which offer up to 65 GHz of bandwidth and 12-bit resolution. This bandwidth supports current automotive SerDes baud rates and accommodates future increases, while the 12-bit resolution ensures accurate measurement of pulse-amplitude modulated (PAM) multi-level signaling used in ASA ML.
The QPHY2-ASA software and WaveMaster 8000HD oscilloscopes support reliable data transmission testing for autonomous vehicle technologies. For more details on Teledyne LeCroy’s automotive SerDes test solutions, visit.
