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.
