EP91Z3E

Part Number:EP91Z3E

Overview

EP91Z3E is a 3 Ghz HDMI Repeater with 4K2K Super Resolution Engine (SRE), Re-Timed Audio and dual HDMI outputs. The chip supports one 3 Ghz HDMI port and two 3 Ghz HDMI TX ports with Video Scaling, Audio Re-Timing and HDCP Repeater function.
The on-chip Explore SRE can convert video input stream from 1080p to 4K2K at 30 Hz frame rate with image detail reconstruction. Or from 4K2K to 1080p at 30 Hz frame rate. The Re-Timed Audio can convert video timing mode (register programmable) and keep audio stream intact.
Each HDMI TX port can be configured to output Scaled Video, Re-Timed Audio or by-pass AV stream from HDMI RX port.
The chip is compliant with HDMI 1.4 and supports SD/HD Audio and HD/3D/4K2K Video. The chip also supports on-chip HDCP
RX/TX engines and EDID RAM.
The chip also integrated with a eFlash MCU to make user’s applications very easy.
