The TMDS171 is a digital video interface (DVI) or high-definition multimedia interface (HDMI) retimer. The TMDS171 supports four TMDS channels, Audio Return Channel (SPDIF_IN/ARC_OUT), Hot Plug Detect (HPD) and Digital Display Control (DDC) interfaces. The TMDS171 supports signaling rates up to 3.4 Gbps to allow for the highest resolutions of 4k2k30p 24 bits per pixel and up to WUXGA 12-bit color depth or 1080p with higher refresh rates. The TMDS171 automatically configures itself as a re-driver at low data rate (< 1 Gbps) or as a re-timer above this data rate.
The TMDS171 supports dual power supply rails of 1.2 V on VDD and 3.3 V on VCC for active power reduction. Several methods of power management are implemented to reduce overall power consumption. TMDS171 supports fixed EQ gain or adaptive EQ control by I2C or pin strap to compensate for different lengths input cable or board traces.
