Overview
The TMDS181RGZT is a 6 Gbps TMDS (Transition-Minimized Differential Signaling) retimer produced by Texas Instruments. This device is designed to support high-definition multimedia interface (HDMI) and digital video interface (DVI) applications. It is capable of handling signaling rates up to 6 Gbps, enabling support for high resolutions such as 4k2k60p with 24 bits per pixel, WUXGA with 16-bit color depth, or 1080p with higher refresh rates. The TMDS181RGZT can be configured to support the HDMI 2.0a standard and automatically switches between redriver and retimer modes based on the data rate.
