T2M HDMI HDMI eARC Tx Controller IP

HDMI eARC Tx Controller IP

Description and Features

HDMI eARC TRANSMITTER interface provides full support for the two-wire HDMI eARC Tx Controller IP synchronous serial interface, compatible with HDMI specification. Through its HDMI eARC Tx compatibility, it provides a simple interface to a wide range of lowcost devices. HDMI eARC Tx Controller IP is proven in FPGA environment. The host interface of the HDMI eARC TRANSMITTER can be simple interface or can be AMBA APB, AMBA AHB, AMBA AXI, VCI, OCP, Avalon, PLB, Tilelink, Wishbone or Custom protocol.
