Mixel Achieves First-Time Silicon Success with MIPI D-PHY RX+ Configuration

June 8, 2015 | By Business Wire News

SAN JOSE, Calif.

Mixel^®, the leader in mobile mixed-signal intellectual property (IP), announced today that its RX⁺ D-PHY^SM IP is silicon-proven in both 40nm and 28nm process nodes and is going into high-volume production in customer’s product. The MIPI^® D-PHY RX⁺ is a Mixel proprietary implementationof the Camera Serial Interface (CSI^SM) and Display Serial Interface (DSI^SM) D-PHY Receiver optimized for reduced area and power, while achieving full-speed production and in-system testing, and higher performance compared to traditional receiver configurations.

As MIPI expands beyond the traditional mobile platform into safety sensitive applications, such as automotive and medical applications, full-speed, in-system testability and diagnostics are becoming of paramount importance.

Traditional D-PHY implementations that support full-speed production test use the Universal configuration, which requires the inclusion of multiple high-speed and low-power transmitters. The innovative RX⁺ configuration developed by Mixel and deployed by its first-tier customer, uses only one transmitter to test all the multiple data channels, thus saving substantial area and standby power, and allowing higher data rate performance by minimizing the capacitive load at the high-speed serial interface pins.

This Mixel proprietary implementation of the MIPI D-PHY combines the small area and improved performance of RX configuration with the testability and diagnostics of the Universal configuration; the best of both worlds.

Since the D-PHY TX area is significantly larger than that of RX, Mixel’s RX⁺ configuration has smaller area and standby current, as only 2 transmitters are need instead of the 5 transmitters that would be needed for a conventional 4 data-lanes Universal lane configuration. The reduction in area is 35% while standby power reduction is 50%.

The RX⁺ configuration was developed and implemented by Mixel independent of the MIPI^® Alliance and is Compliant with MIPI Alliance’s D-PHY^SM RX. Mixel achieved first-time silicon success with this IP in both 40nm and 28nm process nodes.

“This is a great addition to our expanding and differentiated MIPI portfolio,” said Ashraf Takla, Mixel’s President and CEO. “We are delighted to see that this unique Mixel MIPI IP is being integrated into our customer’s products at multiple nodes and going into high-volume production.”

Mixel has co-authored a technical article describing this differentiated IP, and will be demonstrating many of its own and its customers’ products at DAC 2015, June 8^th through the 10^th at the San Francisco Moscone Center.
