Supports data rates up to 2.25 Gbps, enabling 1080p deep signaling (TMDS) buffer featuring equalized inputs and color (12-bit color) HDMI formats and greater than UXGA pre-emphasized outputs. The ADV3003 features 50 input (1600 1200) DVI resolutions. and output terminations, providing full-swing output signal 2. The 12 dB input cable equalizer enables the use of long recovery and minimizing reflections for improved system cables at the input. For a typical 24 AWG cable, the signal integrity. The ADV3003 is targeted at HDMI/DVI ADV3003 compensates for more than 20 meters at data applications and is ideal for use in systems with long cable rates up to 2.25 Gbps. runs, long PCB traces, and designs with interior cabling. 3. The selectable 6 dB of output pre-emphasis allows the ADV3003 to drive high loss output cables or long PCB traces. The ADV3003 is provided in a 40-lead, LFCSP, surface-mount, 4. Matched 50 on-chip input and output terminations RoHS-compliant, plastic package and is specified to operate improve system signal integrity. over the 40C to +85C temperature range. 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. Rev.
