The MIPI® D-PHY TX+ is a Mixel proprietary implementation of the MIPI Camera Serial Interface 2 (CSI-2) and Display Serial Interface (DSI) D-PHY Transmitter. It is optimized to achieve full-speed production testing, in-system testing, and higher performance compared to traditional configurations, while reducing area and standby power.
As MIPI adoption continues to expand beyond its traditional mobile platform use-cases into safety sensitive applications such as automotive and medical, full-speed, in-system testability and diagnostics have become of paramount importance. Mixel TX+ configuration was created to address those safety and reliability sensitive applications.
Full-speed production testing using traditional D-PHY requires the use of Universal configuration, which includes multiple high-speed and low-power receivers not required for functional operation. Mixel’s proprietary TX+ configuration achieves this with minimal area overhead, resulting in a substantial reduction of 30% in area and 40% in standby power. That also enables higher data rate operation by minimizing the capacitive load at the high-speed serial interface pins and isolating the loop back test from any loading on the serial interface pins, while achieving 100% test coverage of the complete IP.
The receiver implemented in the TX+ provides the testability and diagnostics of the D-PHY Universal configuration with the smaller footprint and improved performance of D-PHY TX. Mixel’s D-PHY TX+ is truly the best of both.
