Mixel's MIPI C-PHY/D-PHY Combo IP is Silicon-Proven in Multiple Nodes


Mixel®, the leader in mobile mixed-signal intellectual property (IP), announced today that its MIPI® C-PHYSM/MIPI D-PHYSM combo IP is silicon-proven in both 40nm and 55nm process nodes and is going into high-volume production in its customer's products. The IP is also available in 28nm. The MIPI C-PHY/MIPI D-PHY combo supports the MIPI Camera Serial Interface (CSI (News - Alert)SM) and MIPI Display Serial Interface (DSISM).

Mixel's MIPI C-PHY/MIPI D-PHY combo IP is a high-frequency, low-power, low-cost, physical layer. The PHY can be configured as a MIPI master or MIPI slave, supporting camera interface MIPI CSI-2SM v1.2 and display interface MIPI DSI v1.3 applications in the MIPI D-PHY mode. It also supports camera interface MIPI CSI-2 v1.3 and display interface MIPI DSI-2 SM v1.0 applications in the MIPI C-PHY mode. The high-speed signals have a low voltage swing, while low-power signals have large swing. High-speed functions are used for high-speed data traffic, while low power functions are mostly used for control.

Compared to the MIPI D-PHY, the MIPI C-PHY supports data rates 2.28 higher at the same transition rate. This, together with the MIPI C-PHY's embedded clock, results in lower power at higher data rates, and potentially allows for the use of fewer interface pins. The MIPI C-PHY also enables each lane, consisting of a trio, to operate totally independent of the other lanes, making each lane easily assigned to a different link. By embedding the clock, the MIPI C-PHY eliminates the frequency interference caused by the MIPI D-PHY clock lane.

The combo IP not only shares the serial interface pins, but Mixel's implementation also reuses all the MIPI D-PHY functional blocks for the MIPI C-PHY, minimizing area and leakage power



"We see a lot of traction with this combo IP, which has been designed into several Mixel customers' SOCs," said Ashraf Takla, Mixel's President and CEO. "Clearly, supporting MIPI D-PHY, the most widely adopted MIPI PHY today, while enabling the transition into higher data rate, next-generation products supporting MIPI, is a very powerful proposition."

The advantages that the MIPI C-PHY offers come at the expense of additional complexity, such as unique clock and recovery, which is programmable based on data rate. The MIPI C-PHY has seen wide adoption in camera applications, and display providers have also started supporting the MIPI C-PHY in some of their offerings.


Mixel will be co-presenting a technical presentation with Qualcomm (News - Alert) Technologies, Inc. titled, "MIPI C-PHY/D-PHY Dual Mode Subsystem Performance & Use Cases " and will be demonstrating many of its own and its customers' products at MIPI DevCon 2017, October 27, 2017, in Bangalore, India, and October 31, 2017, in Hsinchu City, Taiwan.
