ADV3002BSTZ

Overview

The ADV3002BSTZ is a 4:1 HDMI/DVI switch featuring equalized TMDS inputs, DDC/CEC buffers, and EDID replication. It supports data rates up to 2.25 Gbps and pixel clocks up to 225 MHz. The device includes ±8 kV ESD protection on input pins, switchable 50 Ω on-chip terminations, and a loss of signal detect circuit. It operates over a temperature range of 0°C to 85°C in an 80-lead LQFP package.

Feature Summary

• Integrated input cable equalizer compensates for signal degradation in long HDMI runs.
• EDID replication function allows a single external EEPROM to serve all four HDMI ports.
• Bidirectional DDC and CEC buffers with integrated pull-up resistors reduce component count.
• 5 V combiner provides power to auxiliary circuits when local system power is off.

Applications

• Advanced television (HDTV) sets
• Projectors
• A/V receivers
• Set-top boxes

Procurement Notes

Verify the specific suffix BSTZ corresponds to the RoHS-compliant 80-lead LQFP package variant. Confirm the revision level matches current design requirements, as specifications are subject to change without notice. Ensure compatibility with 3.3 V AVCC and 5 V AMUXVCC supply rails during integration.

Selection Notes

Select this component for systems requiring switching between multiple HDMI or DVI sources while maintaining signal integrity over extended cable lengths. The built-in equalization and EDID replication simplify board layout by reducing external memory requirements. Verify that the 80-lead LQFP package fits within the available PCB area constraints.

Part Context

FAQ

How does the ADV3002 handle EDID information for multiple sources?

The device features an EDID replication function that stores EDID data in on-chip SRAM, allowing a single external EEPROM to be shared across all four HDMI ports simultaneously.

What is the purpose of the 5 V combiner in this switch?

The 5 V combiner aggregates power from the four HDMI source inputs to provide power to the EDID replicator and CEC buffer, ensuring functionality even when the local system power is off.
