What is MIPI C-PHY

Larger capacity and higher speed of data interfaces are required in accordance with the high resolution trend of cameras and displays ⇒　the MIPI C-PHY, which is the new data interface has been established and will be released to the market

*MIPI=Mobile Industry Processor Interface Alliance

	D-PHY		C-PHY
	Two transmission lines as one pair： D+－D-		Three transmission lines： VA-VB, VB-VC, VC-VA
Transmission system	Two-line differential transmission system High speed, frequency up for large capacity transmission		Sending side: three different potentials Receiving side ： extract the differential part between each two lines VA-VB, VB-VC, VC-VA *Symbol Gain =2.28bit/symbol
Data rate	Ver1.2	2.5Gbps / Pair	Ver1.0	2.5Gsps(=5.7Gbps / Trio) Same signal numbers, approximately 1.5times D-DHY
Data transmission power consumption	---		Low power consumption
Equipment design	Need clock signal		no clock signal, easy to allocate

Merit of using C-PHY for mobile devices such as smartphones: １）Reduction of wiring area due to large capacity data transmission and high speed; ２）Reduction of transmission power consumption; ３）Flexibility up of circuit layout
