Overview
The TMDS181IRGZT, produced by Texas Instruments, is a high-performance 6 Gbps TMDS (Transition-Minimized Differential Signaling) retimer designed for digital video interfaces such as HDMI and DVI. This component supports signaling rates up to 6 Gbps, enabling it to handle high-resolution video signals including 4k2k60p at 24 bits per pixel and up to WUXGA with 16-bit color depth or 1080p with higher refresh rates. The TMDS181IRGZT is compatible with HDMI 2.0a standards and can automatically configure itself as a redriver at low data rates (<1.0 Gbps) or as a retimer at higher data rates, supporting HDMI 1.4b up to 3.4 Gbps.
