ADV3003

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.

Applications

• Multiple input displays
• Advanced television set (HDTV) front panel connectors
