3 Description
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 redriver
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.
