Overview
The TMDS181RGZR, produced by Texas Instruments, is a 6 Gbps TMDS (Transition-Minimized Differential Signaling) retimer designed for high-definition multimedia interface (HDMI) and digital video interface (DVI) applications. This component supports data rates up to 6 Gbps, enabling it to handle high-resolution video signals such as 4k2k60p at 24 bits per pixel and up to WUXGA with 16-bit color depth or 1080p with higher refresh rates. The TMDS181x automatically configures itself as a redriver at low data rates (<1.0 Gbps) or as a retimer at higher data rates, supporting both HDMI 1.4b and HDMI 2.0a standards.
