SmartDV’s HDMI eARC Transmitter IP is a fully featured Enhanced Audio Return Channel transmitter solution purpose-built for SoC designs requiring reliable, high-fidelity audio return connectivity across TV, AV receiver, and soundbar applications. Compliant with the HDMI eARC protocol standard as defined in HDMI Specification 2.2, it delivers complete eARC transmitter functionality with single-ended non-differential split outputs, supporting the transmission of both encrypted and unencrypted 2-channel and multi-channel L-PCM, IEC 61937, and one-bit audio formats.
Designed for the practical integration requirements of modern TV and source device SoC designs, the IP supports biphase-mark encoding and falling-edge modulation for standards-compliant audio signal transmission. Its complete eARC Common Mode Data Channel function support including discovery and disconnect, heartbeat, status bits, audio latency control, and capabilities data structure give TV and AV source SoC teams a production-ready eARC transmitter implementation for the latest high-bitrate, uncompressed multi-channel audio formats including Dolby Atmos and DTS:X.
Built for design flexibility and silicon efficiency, the IP core is highly configurable for both ASIC and FPGA implementations, with a strong focus on area optimization, power management, and peak performance. Its parameterized architecture and clean host interface enable fast integration across a wide range of process nodes and target applications.
