EP92H1

Part Number:EP92H1

Overview

EP92H1 is a Audio Interface Converter which converts the audio among different interfaces. This chip converts the audio input data in IIS, SPDIF, DSD or HBR format to the ARC/eARC TX. Besides, this chip converts the input from ARC/eARC RX to the digital IIS, SPDIF, DSD or HBR output. This chip also provides the SPDIF data extraction and converts to IIS format. The chip is compliant with HDMI 2.1 specifications.
