HDMI retimer allows for the highest resolutions and colour depths

The Texas Instruments TMDS181x is a digital video interface (DVI) or high-definition multimedia interface (HDMI) retimer. The device supports four TMDS channels, audio return channel (SPDIF_IN/ARC_OUT), and DDC interfaces. It supports signalling rates up to 6Gbps to allow for the highest resolutions of 4k2k60p 24 bits per pixel and up to WUXGA 16-bit colour depth or 1080p with higher refresh rates. The device can be configured to support the HDMI2.0a standard. It 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 to 3.4Gbps The device supports dual power supply rails of 1.2V on VDD and 3.3V on VCC for power reduction. Several methods of power management are implemented to reduce overall power consumption. It 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.
