Overview
The ADV3003ACPZ, manufactured by Analog Devices Inc., is a 4-channel transition minimized differential signaling (TMDS) buffer designed for HDMI and DVI applications. This component features equalized inputs and pre-emphasized outputs, making it ideal for systems with long cable runs, long PCB traces, and interior cabling. The ADV3003ACPZ is packaged in a 40-lead, LFCSP (Lead Frame Chip Scale Package), surface-mount, RoHS-compliant plastic package and operates over a temperature range of −40°C to +85°C.

Key Features
- 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.
- 12 dB input cable equalizer to compensate for long cables, supporting over 20 meters at data rates up to 2.25 Gbps for a typical 24 AWG cable.
- Selectable 6 dB of output pre-emphasis to drive high loss output cables or long PCB traces.
- Matched 50 Ω on-chip input and output terminations to improve system signal integrity.
- External control pins (PE_EN and TX_EN) for setting output pre-emphasis and disabling the transmitter and on-chip input terminations, respectively.
Applications
The ADV3003ACPZ is primarily used in HDMI and DVI applications, particularly in systems that require signal integrity over long cable runs or PCB traces. This includes:
- HDMI and DVI interfaces in consumer electronics such as TVs, monitors, and gaming consoles.
- Systems with interior cabling and long PCB traces where signal degradation is a concern.
