3 Description
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.
