The offerings provide support to testing advanced infotainment and driver assistance systems for accurate physical-layer design verification

The rise of speed and bandwidth in automotive in-vehicle technologies has led test equipment vendors to adapt to changing standards. To support this, Keysight Technologies has partnered with Sony Semiconductor Solutions Corporation and Rosenberger to introduce new automotive serialiser/deserialiser (SerDes) transmit and channel test applications, as well as an automotive adaptor portfolio, respectively, to verify mobile industry processor interface (MIPI) A-PHY and Automotive SerDes Alliance (ASA) standards. 

High-speed automotive SerDes interfaces enable seamless data transport for uninterrupted in-vehicle video, audio and communication. High bandwidth, reliability and performance of SerDes serial links are key requirements in automotive applications, which enable advanced infotainment and driver-assistance systems (ADAS) in modern vehicles.

While the AE2010T automotive SerDes transmitter test application enables automatic configuration of each result utilising a Keysight Infiniium UXR-series oscilloscope, the AE2010L automotive SerDes channel test application allows automation of network analyzer tests. Together, these applications provide critical information to maintain data integrity and low loss networks, while meeting current automotive SerDes specifications.

“Automotive SerDes standards are important to our strategy of embedding a serializer on our image sensors. We are pleased to work with Keysight to validate our design against emerging SerDes specifications,” said Kenji Onishi, General Manager, Automotive Business Department, Sony Semiconductor Solutions Corporation. “Keysight’s automotive SerDes compliance test solution will allow us to confidently deliver new capabilities to our customers (which include chipset vendors and OEMs).”

Collaboration with Rosenberger

Keysight’s partnership with Rosenberger offers industry-accepted adaptors for automotive SerDes and high-speed data links.

“Our customers will benefit from testing solutions for all automotive connector interfaces, which are either standardised or accepted to become global standards for automotive high-speed data transmission soon. This includes the most innovative and cutting-edge connector solutions for coaxial and differential transmission channels, such as FAKRA, HFM, HSD or H-MTD,” said Hauke Schütt, executive vice president of Test & Measurement at Rosenberger. “Rosenberger is pleased to deliver automotive test adaptors to Keysight, which assist device makers in the support of new automotive in-vehicle networks.”

The SerDes transmitter and channel test applications offer the following key benefits:

  • Automatic configuration and calibration of all required test equipment for a reduced overall test time.
  • Extensive range of tests for standards conformance of MIPI A-PHY and ASA, to reduce cost and save multiple installations and license purchases.
  • Test framework to report multi-trial results, with a full array of statistics for each measurement.
  • Quick, accurate and repeatable test results for validation and debugging.
  • Channel test software runs on a E5080B ENA Vector Network Analyzer, PXI Vector Network Analyzers, or Streamline Series USB Vector Network Analyzers and provides the framework for connectors, cables, and harnesses to quickly test automotive SerDes links.

“In-vehicle networking is an important technology for our customers, and we have observed a great deal of market dynamics as data rate requirements keep increasing. At Keysight, we aim to support a wide range of in-vehicle network interfaces ranging from Automotive Ethernet through MIPI A-PHY to ASA,” said Thomas Goetzl, vice president and general manager for Keysight’s Automotive & Energy Solutions business unit.
