Practical Experiences in MIPI D-PHY & C-PHY Receiver Testing (Introspect & Trust-Tek)
Abstract: Whereas published MIPI Alliance specifications for MIPI D-PHY and MIPI C-PHY strive to define and illustrate performance parameters at the highest theoretical levels, practical implementations often correspond to widely varied system requirements. As such, implementers often struggle with a desire to adhere to certain key requirements defined in the specifications -- such as receiver stressed eye testing -- while operating within contexts that do not warrant a literal interpretation of the methodology described in these specifications. For example, operating a MIPI D-PHY or MIPI C-PHY link at 500 Mbps (or 500 Msps) results in very little signal losses even on the long channel model described in the MIPI Alliance specifications. Yet, signals are degraded and receivers are stressed in such system environments. In this talk, we address some of these conundrums and offer best practices in test. We focus on contextual requirements and help separate component-level testing/characterization needs from system-level ones.
