EP9555E is a 3-Port Low Power HDMI/MHL receiver with video up/down Scaler and CCIR 601/656 digital video output. The chip is compliant with HDMI 1.4, MHL 2.0 and HDCP 1.4 specifications. The chip supports 1 HDMI/MHL dual mode port (Port 1) and 2 MHL ports (Port 0 and Port 2). The chip supports Video Output up to 1080p 60 Hz. The chip also supports 2-channel IIS and S/PDIF Audio Outputs. The chip integrates Equalizer Switches, HDMI/MHL core, HDCP engine, Video Scaler and EDID RAM in a single chip.
The on-chip Video 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 useful for converting an EIA standard video to fit an LCD panel in different resolution.
EP9555E is also integrated with an 8-bit MCU on-chip for HDMI/MHL/HDCP/Scaler control and CEC/RCP applications. With this embedded MCU user is not required to develop the firmware and it is very easy for user to use the chip.
