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

Two transmission lines as one pair: D+-D- Three transmission lines: VA-VB, VB-VC, VC-VA
Transmission system

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

  • *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
