Abstract: The three high-speed serial standards namely - MIPI D-PHY, MIPI M-PHY and MIPI C-PHY, although having similarities in terms of target segment and application use cases, do have wide contrasts with respect to electrical specifications. MIPI D-PHY is a forwarded clock system, MIPI M-PHY has maximum toggle rate of up to ~12Gbps and MIPI C-PHY is 3-level 3-wire signal. Inevitably, engineers will encounter varied issue/challenges while debugging or testing these designs. This presentation shall provide real world problems faced and the process of uncovering them early on using the test and measurement equipment & solutions. The solution could be in terms of measurement & analysis of signal characteristics, probing with fidelity and waveform generation with precision. In addition, this session shall highlight the test solutions you will need to support the upcoming revisions of these MIPI PHY specifications.

Ramesh from the past 20+ is working on developing compliance measurements for various technology like HDMI, MHL, Ethernet and MIPI . He also contributes to Standards specifications and test methodologies of many high speed serial technologies. Apart from measurement development, he also involved in solving the customer issues relating to Test and measurement and also instrumental in developing the system level solution for Testing. He holds 5 US patents for various T & M functionalities/procedures.

Parthasarathy, Chair of the MIPI Test Working group at MIPI Alliance, is a System Engineer for MIPI technology segment at Tektronix. He is involved for the past 9 years working on signal generation solutions for waveform generators & measurement solutions for real-time oscilloscopes. His current focus is on test solutions for MIPI High Speed PHY Technologies. He holds a US patent for a method to emulate crosstalk. Prior to joining Tektronix, Partha was involved with embedded device drivers for mobile platforms and has designed algorithms for wide range of DSP solutions.
