MIPI技術與版本因為時代進步一值更新,在實體層除了M-PHY,D-PHY之外,又多出個 C-PHY
下圖可以看出 C-PHY 的位置



C-PHY的訊號線由3 條 trio成一組,總共可以有三組,也就是 9 條 trios

粗略規格列在以下提供給各位參考,我個人覺得C-PHY 是 D-PHY的改進版,除了速度更快之外,更是重新使用了 D-PHY的 LP mode
----
C-PHY
  • 3-wire(trio A,B,C) signal represents a lane.
  • New encoder scheme to increase the number of bits per symbol(~2.5bit/symbol)
  • Projected rate at 2.5GSym/s(effective data rate of 5.7Gbps)
  • Signal is transmitted single-ended but received using differential receivers.
  • Reuse LP mode defined in D-PHY.
(Note: D-PHY 2.0 data rate 3.5Gbps)
