EP92A2E4
Overview
 
EP92A2E4 is an HDMI 1.4a 3-IN 1-OUT Repeater/Switch/MCU combo suitable for Home Theater application. The on-chip HDMI/HDCP/CEC controller makes the user very easy to use the chip. It manages HDMI and HDCP 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 chip supports 3 HDMI input ports (Port 0, Port 1 and Port 2) where Port 0 and Port 1 input to an HDMI Repeater and Port 2 input to an HDMI Switch. The HDMI Repeater supports HDCP decryption, audio outputs, audio inputs and HDCP re-encryption. The HDMI Switch supports TMDS switching and DDC switching. The chip supports ARC (Audio Return Channel) RX and is compliant with HDMI 1.4a. The chip supports SD/HD/DSD Audio in IIS and SPDIF format. The chip supports HD, 3-D and 4K2K Video up to 297 Mhz TMDS clock. The chip also supports 2 ports of on-chip EDID RAM and Power Regulator to save system cost.
