EP94Z3 is an HDMI 1.4 Repeater with Audio, VGA and Scaled LVDS outputs. The chip supports 1 HDMI/MHL RX port and 1 HDMI TX port with repeater function. The chip also supports decoded Audio, VGA and scaled LVDS outputs.
With the Scaled LVDS output, the chip provides a converted video output which can be in a different resolution from that of the HDMI input. The on-chip Scaler is able to scale the input video up or down to any resolution within the range of 0.5X to 2X in both Horizontal and Vertical direction. This is adequate for converting an EIA standard video to fit an LCD panel in different resolution.
The chip is compliant with HDMI 1.4 and supports SD/HD Audio and HD/3D Video up to 1080p. The chip also supports on-chip HDCP RX/TX engines and EDID RAM.
