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.

PRODUCT HIGHLIGHTS
1. 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.
2. 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.
3. The selectable 6 dB of output pre-emphasis allows the
ADV3003 to drive high loss output cables or long PCB traces.
4. Matched 50 Ω on-chip input and output terminations
improve system signal integrity.
5. An external control pin, PE_EN, sets the output
pre-emphasis to either 0 dB or 6 dB.
6. 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.
