The TMDS181x can be configured to support the HDMI2.0astandard. The TMDS181x automatically configures itself as a redriver at low data rate (<1.0Gbps) or as a retimer above this data rate. Redriver mode supports HDMI1.4b with data rates up to3.4 Gbps

The TMDS181x supports dual power supply rails of 1.2 V on V_DD and3.3 V on V_CC for power reduction. Several methods of power management areimplemented to reduce overall power consumption. TMDS181x supports fixed receive EQ gain oradaptive receive EQ control by I²C or pin strap to compensate fordifferent lengths input cable or board traces.
