HDMI Repeater > Repeater
EP94R3K is an HDMI 1.4a 4-IN 1-OUT Repeater with ARC and Instant Port Switching (IPS) feature which is suitable for Audio Amplifier applications. The chip supports 4 HDMI input ports (Port 0, Port 1, Port 2 and Port 3), 4 HDCP ciphers, 1 HDMI output port and Audio Outputs in IIS and SPDIF. The audio output and HDMI output can be selected from the same or different sources. The chip supports ARC (Audio Return Channel) RX and is compliant with HDMI 1.4a. The chip supports SD/HD Audio and HD/3-D Video up to 225 Mhz TMDS clock. With 4 HDCP ciphers the chip supports very fast port switching without the need to redo HDCP authentication when port switching occurs. This feature is referred to as Instant Port Switching (IPS). The chip also supports 4 ports of on-chip EDID RAM to save system cost.
