Overview
EP9442U is an 3.4G Hz HDMI 1.4 4-IN 2-OUT Repeater, ARC and Instant Port Switching (IPS) feature which is suitable for Switch Box, TV with PIP/POP and Audio Amplifier applications. The chip supports 4 HDMI input ports and 2 HDMI output ports (TX0, TX1). The chip supports 4 HDCP RX ciphers and 2 HDCP TX ciphers. With 4 HDCP RX 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.
The chip supports Audio Outputs in IIS and SPDIF. The audio output and HDMI outputs can be selected from the same or different sources. The audio for the HDMI output can be from a regenerated LPCM audio source (input from IIS_*_IN pins) or the original audio from the selected HDMI input port. The chip supports ARC (Audio Return Channel) RX and is compliant with HDMI 1.4. The chip supports SD/HD Audio and HD/3-D Video up to 340 Mhz TMDS clock.
Features
