The SiI9437/SiI9438 ARC/Enhanced ARC receiver/transmitter from Lattice Semiconductor adds higher bandwidth Enhanced Audio Return Channel (eARC) capability to HDMI based designs.
The SiI9437/SiI9438 ARC/Enhanced ARC receiver/transmitter support audio bit rates up to 98 Mb/s (36.8 Mb/s payload). Manufacturers of televisions, audio/video receivers, and sound bars can use these devices to implement eARC with up to 8- channels of 24-bit, 192 kHz audio. This new high bit rate, low jitter audio interface transmits over standard HDMI with Ethernet cable using the available differential twisted pair of pins 14 and 19. The devices are backward-compatible with HDMI 1.4 Audio Return Channel, for connectivity with legacy ARC devices. Implementing eARC into consumer electronics products helps to ensure greater interoperability and forward-compatibility without compromise. This is especially important as new devices with Dynamic HDR, Variable Refresh, and other HDMI 2.1 features come to market. The SiI9437/SiI9438 include support for the eARC Common Mode Data Channel, used for Discovery, Capabiity Detection, Heartbeat, and Lipsync features of eARC. The SiI9437/SiI9438 design enables integration in conjunction with existing HDMI transmitters and receivers, and operates independently of the HDMI frequency, mode, and encoding format. No HDMI 2.1 or HDMI 2.0 dependency exists; the devices can be integrated with HDMI transmitter/receivers using any version of HDMI.
