ADV3003ACPZ-R7

Overview

The ADV3003ACPZ-R7 is a four-channel TMDS buffer designed for HDMI and DVI applications. It features equalized inputs with 12 dB boost and selectable pre-emphasized outputs (0 dB or 6 dB). The device supports data rates up to 2.25 Gbps and pixel clocks up to 225 MHz, enabling 1080p deep color formats. It includes matched 50 Ω on-chip input and output terminations to minimize reflections. Powered by a single 3.3 V supply, it operates within a temperature range of -40°C to +85°C. The component is housed in a 40-lead, 6 mm × 6 mm LFCSP package.

Feature Summary

• Provides 12 dB fixed input equalization to compensate for signal loss in long HDMI cables.
• Offers selectable 6 dB output pre-emphasis to drive high-loss cables or long PCB traces.
• Integrates matched 50 Ω on-chip terminations at both input and output ports.
• Includes transmitter disable feature that reduces power dissipation and indicates link status.

Applications

• Multiple input displays
• Advanced television set front panel connectors
• HDMI/DVI cable extenders

Procurement Notes

Verify the specific ordering suffix matches the required reel quantity and tape configuration. Confirm the package variant corresponds to the 40-lead LFCSP form factor. Ensure the revision level aligns with design specifications. Check for RoHS compliance documentation if required by regulatory standards. Validate the manufacturer source against official Analog Devices channels.

Selection Notes

Select this component when buffering four TMDS channels is required for HDMI 1.3 receive-compliant designs. It is suitable for systems involving long cable runs exceeding standard length limitations. Use when integrated termination resistors are needed to simplify PCB layout. Consider for applications requiring low added jitter and minimal signal degradation.
