EP9553(E) is a 3-Port Low Power HDMI/MHL/MCU combo receiver which is compliant with HDMI 1.4 and MHL 2.0 specifications. The on-chip HDMI/MHL/CEC/CBUS controller makes the user very easy to use the chip. It manages HDMI/MHL protocol switching automatically without the need for user to develop firmware. The CEC Controller provides the CEC physical layer transceiver and handles the protocol layer automatically. The CBUS Controller provides the translation between the MHL RAP/RCP Request and the HDMI CEC Command automatically. The CBUS Controller also supports the MSC UCP protocol. The chip supports 1 HDMI/MHL dual mode port (Port 1) and 2 MHL ports (Port 0 and Port 2). The chip supports Video Output up to 1080p 60 Hz. The chip also supports 2-channel IIS and S/PDIF Audio Outputs. The chip integrates Equalizer Switches, HDMI/MHL core, HDCP engine and EDID RAM
