HDMI Repeater > Repeater

Part Number:EP92A3E

Overview

EP92A3E is an HDMI/MHL 1.4 3-IN 1-OUT Repeater suitable for Home Theater and Bar Speaker applications. The chip supports 1 HDMI/MHL dual mode input port (Port 0) and 2 HDMI input ports (Port 1 and 2). The chip supports HDCP decryption, audio outputs, audio inputs and HDCP re-encryption in repeater mode. The chip supports SD/HD/DSD Audio in IIS and SPDIF format. The chip supports HD, 3D, and 4K2K Video up to 300 Mhz TMDS clock.
The chip is also integrated with an eFlash MCU. It manages HDMI, HDCP repeater, and handle all the GPIO control (DDC, HPD, +5V detect...) automatically without the need for user to develop firmware. The MCU provides the CEC physical layer transceiver and handles the protocol layer automatically that make user’s applications very easy.
