GENERAL DESCRIPTION
The ADV3003 is a 4-channel transition minimized differential
signaling (TMDS) buffer featuring equalized inputs and
pre-emphasized outputs. The ADV3003 features 50 Ω input
and output terminations, providing full-swing output signal
recovery and minimizing reflections for improved system
signal integrity. The ADV3003 is targeted at HDMI™/DVI
applications and is ideal for use in systems with long cable
runs, long PCB traces, and designs with interior cabling.
The ADV3003 is provided in a 40-lead, LFCSP, surface-mount,
RoHS-compliant, plastic package and is specified to operate
over the −40°C to +85°C temperature range.

Supports data rates up to 2.25 Gbps, enabling 1080p deep
color (12-bit color) HDMI formats and greater than UXGA
(1600 × 1200) DVI resolutions.
The 12 dB input cable equalizer enables the use of long
cables at the input. For a typical 24 AWG cable, the
ADV3003 compensates for more than 20 meters at data
rates up to 2.25 Gbps.
The selectable 6 dB of output pre-emphasis allows the
ADV3003 to drive high loss output cables or long PCB traces.
Matched 50 Ω on-chip input and output terminations
improve system signal integrity.
An external control pin, PE_EN, sets the output
pre-emphasis to either 0 dB or 6 dB.
An external control pin, TX_EN, simultaneously disables
both the transmitter and the on-chip input terminations.
This feature reduces the power dissipation of the ADV3003
and indicates to a connected source when the ADV3003 is
disabled.

... ADV3003 THEORY OF OPERATION INTRODUCTION The primary function of the ADV3003 is to buffer the four high speed channels of a single HDMI or DVI link. The HDMI/DVI link consists of four differential, high speed channels and four auxiliary single-ended, low speed control signals. The high speed channels include a data-word clock and three transition minimized differential signaling (TMDS) data channels running at 10× ...

... HDMI/DVI receiver, which On provides a second set of matched terminations in accordance On with the HDMI 1.3 specification. If neither receiver nor receiver termination is connected to the output of the ADV3003 in the end-application, each ADV3003 output pin should be tied to 3.3 V through a 50 Ω resistor.

... The ADV3003 provides input equalization can compensate for the signal degradation of long input cables. In addition, the ADV3003 can also provide pre-emphasis that boosts the output TMDS signals and allows the ADV3003 to precompensate when driving long PCB traces or high loss output cables ...

... TMDS traces is more sensitive to the PCB layout. Regardless of the data being carried on a specific TMDS channel, or whether the TMDS line is at the input or the output of the ADV3003, all four high speed signals should be routed on a PCB in accordance with the same RF layout guidelines. ...
