Diodes Incorporated has released what it claims to be the industry’s first HDMI 2.1 transparent, linear ReDriver optimized for power and cost in digital TVs, laptop and desktop computers.

Able to support video resolutions up to 10K, the PI3HDX12211 supports speeds of up to 12Gbit/s per channel and is transparent to channel link training, rate, and coding. It offers ultra-low signal latency to ensure excellent signal integrity in high-performance applications.

HDMI 2.1 is the latest update to the HDMI specification, intended to enable even higher video resolutions and refresh rates. Bandwidth is increased to 48Gbit/s, making it possible to deliver uncompressed 8K video with HDR. The transparent nature of the PI3HDX12211 means it is agnostic to protocol, supporting both static and dynamic HDR. Devices that implement HDMI 2.1 transmit static/dynamic HDR metadata over the interface. The PI3HDX12211 features four differential channels with programmable linear equalization, output swing linearity, and flat gain, controlled through an I2C interface or pin-strapping. Operating from a 3.3V supply, the PI3HDX12211 dissipates just 220mW per channel and maintains a 1200mV peak-to-peak, output swing linearity. As higher video resolutions develop, the PI3HDX12211 will enable the latest visual experience in laptop and desktop PCs, gaming consoles, and DTVs and STBs as well as docking stations and peripherals.
