MIPI D-PHY is a low-power, cost-effective physical layer interface, essential in mobile devices and advanced technology systems. It's a high-speed, source-synchronous interface used in smartphone cameras, smartwatch displays, drones, in-car entertainment, automobile cameras, and radar sensors. This application note explores MIPI D-PHY's features, functionality, and testing practices for device compliance, addressing common issues. It highlights Rohde & Schwarz's equipment for ensuring compatibility and solving issues with MIPI D-PHY, aligned with MIPI D-PHY specification version 2.5.Developed by the MIPI Alliance, D-PHY connects cameras and displays to a host processor via CSI-2 or DSI protocols. It features a master-slave, asymmetrical design for reduced link complexity. Key aspects include a unidirectional clock, optional data signal directions, different data rates for half-duplex operation, point-to-point communication, and high-speed (HS) and low-power (LP) modes for data transfer and battery preservation. In HS mode, D-PHY uses differential signaling with specific impedance, while in LP mode, it operates in a single-ended manner with high impedance termination.The application note from Rohde & Schwarz provides insights into characterizing and debugging MIPI D-PHY, offering conformance verification with MIPI Alliance standards and protocol decoding options.

This document is divided in two parts and starts with an introduction in AC-DC conversion principles in general. It will present the most common circuits used for different power levels. The switching mode power supply (SMPS) converter will be the main focus as they are used everywhere in the electronics. Especially the flyback converter design in different flavors are highlighted. Nevertheless, all measurements are also applicable for other SMPS converter designs operating at higher power levels.In the second part of this document, most relevant testing methods and procedures of an AC-DC converter are highlighted. For each testing section, a fundamental part will be upfront discussed and it is followed by a presentation of a suitable measurement method. In this second part, the device under test (DUT) is considered as black box device and thus the structure is similar. Therefore, the testing parts consists of methods related to input tests, output tests and a combination of both like efficiency. Of course, some test performed at the output of the converter are also relevant for DC-DC converter, e.g. the validation of the output ripple.
