Interoperable and Failure Free MIPI A-PHY® Devices are the Goal — Receiver Testing Can Help
Serializers and De-serializers (SerDes), are common in virtually all high-speed digital bus technologies. They are responsible for taking various digital inputs and sending them over distance using high-speed serial links. Next-generation advanced driver-assistance systems (ADAS) will use sensors like cameras, radar, and lidar with increasingly high resolutions, requiring a network with faster data throughput and greater bandwidth.
Typically, SerDes are built to be asymmetrical; they use a high-speed downlink for data transit, such as from a camera to the central CPU, and a slower uplink for less-demanding tasks like device monitoring and control. This type of link is well suited to remote sensors in the vehicle, which require high-speed outputs but should ideally be limited in their implementation complexity, power requirements, and cost.

Automotive SerDes Receiver Testing Explained
This video highlights the importance of automotive SerDes receiver testing in high speed automotive applications. We will go over the technical challenges and complexity in implementation as well as what the test setup looks like. We will also show how to execute the tests both to specified limits and also to characterize the boundaries of operations of the device under test.
