The Video PHY controller is an important device that provides the interface between Transceivers and video interfaces.This interface either is HDMI or Displayport.HDMI Video PHY controller are more significantly used because they provide the high speed operation for high resolution graphics.However, when high resolution graphics are executed the power consumption of HDMI Video PHY controller becomes critical and this disturb the regular streaming of video or even in some cases may damage the HDMI Video PHY controller.There are various techniques have been adopted but significantly results in power reduction of HDMI Video PHY controller not been achieved.In this paper, the low power design for HDMI Video PHY controller is achieved using unidirectional IO Standard.It is demonstrated that POD IO Standard consumes less power for LVDCI IO Standard.The IO Standard based HDMI Video PHY controller is verified on high frequencies of 2.0 GHz and 6 GHz for providing the maximum line rate of 6 Gb/s.It is determined that power reduction of 51% is accomplished for HDMI based Video using unidirectional POD IO Standard compared to LVDCI IO Standard for 2 GHz operation.For 6 GHz GHz design of HDMI based Video PHY controller the power reduction of 73% is achieved using POD IO Standard compared to LVDCI IO Standard.The proposed design will be to provide high resolution graphics at low power consumption.
