The TMDS181x is a digital video interface (DVI) or high-definition multimedia interface (HDMI™) retimer. The TMDS181x supports four TMDS channels, audio return channel (SPDIF_IN/ARC_OUT), and digital display control (DDC) interfaces. The TMDS181x supports signaling rates up to 6 Gbps to allow for the highest resolutions of 4k2k60p 24 bits per pixel and up to WUXGA 16-bit color depth or 1080p with higher refresh rates. The TMDS181x can be configured to support the HDMI2.0a standard. The TMDS181x automatically configures itself as a redriver at low data rate (<1.0 Gbps) or as a retimer above this data rate. Redriver mode supports HDMI1.4b with data rates up to 3.4 Gbps

The TMDS181x supports dual power supply rails of 1.2 V on V_DD and 3.3 V on V_CC for power reduction. Several methods of power management are implemented to reduce overall power consumption. TMDS181x supports fixed receive EQ gain or adaptive receive EQ control by I²C or pin strap to compensate for different lengths input cable or board traces.
