MIPI D-PHY is a flexible, low-cost, High-Speed serial interface solution for communication interconnection between components inside a mobile device(1). MIPI capturing on ATE systems is historically done using MIPI receiver circuitry (or “BOST” solution) on a device interface board (DIB). While such a solution can parse the data and provide the payload directly, the data captured by these receivers is usually sent to the tester using much lower-speed interfaces such as SPI or I2C, meaning increased overall test times as compared to a direct capture. Moreover, Digital Signal Processing (DSP) is still required to extract the desired info from the payload. By leveraging the Digital Capture (DigCap) function in UltraPin2200’s Digital Signal Source/Capture (DSSC), in conjunction with its Source Synchronous functionality, it is possible to capture MIPI D-PHY payload data directly up to 2.2Gbps per lane. DSP can then be used to extract the payload data and perform any required operation to extract the desired info in one go, providing a faster, more efficient test, with reduced DIB cost and complexity. In this presentation, I will explain the requirements, including DIB signaling, and provide a step-by-step guide on how to implement a MIPI D-PHY direct capture solution on the UltraFLEXplus.
