ADV3002XSTZ - 4:1 HDMI/DVI Switch | Analog Devices
N.º de pieza: ADV3002XSTZ ✗ Fin de vidaADV3002XSTZ Descripción general
An HDMI/DVI video switch is an interface IC that routes one of several high-speed video sources to a display or downstream processing circuit. It belongs to the video-interface hierarchy within interface ICs. Unlike a general-purpose video processor, the ADV3002 primarily performs source selection while preserving the associated control-channel behavior. Equalized transition-minimized differential signaling inputs are intended for systems that include long cable runs, while DDC and CEC buffering supports the auxiliary connections used by compatible display devices.
The principal feature set includes four selectable HDMI/DVI inputs, one switch output, equalization on the high-speed inputs, bidirectional buffering for the Display Data Channel and Consumer Electronics Control line, integrated CEC pull-up resistors, and EDID replication. The verified DigiKey listing describes the interface as I2C/serial and identifies HDMI 1.4a support. These functions consolidate several display-routing requirements into a single dedicated component.
Technically, the ADV3002 is structured as a complete link-switch solution rather than a simple analog multiplexer. Equalization compensates for signal degradation over longer cable paths, while the DDC buffer helps maintain display-control communication through the selected path. EDID replication allows a display identity source to remain associated with the switched output, reducing the need to duplicate EEPROM hardware. Exact input bandwidth, propagation delay, channel count, and electrical limits require confirmation in the manufacturer datasheet.
Typical implementations include HDTV equipment, projectors, set-top boxes, professional video systems, and other installations that route several HDMI or DVI sources to a common display. The equalized inputs are particularly relevant when source-to-switch cable length introduces signal-integrity concerns. In each case, system validation should cover the complete HDMI source, cable, sink, and control-channel combination rather than relying on switch status alone.
Designers should account for the device's lifecycle recommendation and evaluate current program support before beginning a new platform. For an existing design, preserving the original 80-lead LQFP footprint, connector topology, control firmware, EDID arrangement, and cable assumptions is essential. New HDMI designs should normally use a currently recommended switching solution unless legacy compatibility makes ADV3002 operation unavoidable.
This product record consolidates the manufacturer lifecycle position, functional capabilities, package information, ordering-code differences, and practical migration considerations for engineers evaluating the ADV3002XSTZ.

Aplicaciones típicas
ADV3002XSTZ es adecuado para 6 aplicacións: HDTV Source Switching, Projector Input Management, Set-Top Box and TV Integration, Professional Video Routing, Digital Signage Display Hub, Video Wall and Presentation Systems.
HDTV Source Switching
The ADV3002XSTZ fits an established HDTV system in which four HDMI or DVI sources must feed a common display processor. Its four-input selection, equalized TMDS inputs, and bidirectional DDC/CEC buffering keep video routing and display-control signals coordinated through one switch. The 80-lead LQFP implementation also suits boards originally designed around the ADV3002 footprint. Because Analog Devices marks the device as not recommended for new designs, it is most appropriate for repairing or continuing production of compatible legacy equipment rather than specifying it for a fresh platform.
Recomendado
Projector Input Management
A projector installation can use the ADV3002XSTZ to select among several source devices while maintaining DDC and CEC communication with the display. Equalization on the TMDS inputs is relevant when cable length degrades high-speed signal integrity, and the buffered auxiliary paths support the projector control channel. Existing projector electronics based on the 80-lead LQFP layout can preserve their routing architecture. The complete source, cable, switch, and projector combination must be validated because equalization does not eliminate every connector, cable, or sink-related signal-integrity issue.
Recomendado
Set-Top Box and TV Integration
The ADV3002XSTZ is suited to a set-top box or television platform that receives signals from several external sources and needs to route one source into the internal display pipeline. Its HDMI 1.4a association, TMDS equalization, DDC/CEC buffering, and EDID replication support both high-speed video and display negotiation. The integrated functions can simplify a legacy control architecture compared with separate switching and auxiliary-channel components. For new programs, however, the manufacturer's not-recommended-for-new-designs status makes a current HDMI-switching device the preferred starting point.
Recomendado
Professional Video Routing
The ADV3002XSTZ can support a professional or installation video router that accepts four HDMI/DVI sources and connects one to downstream equipment. Equalization helps preserve high-speed signal behavior over longer runs, while bidirectional DDC and CEC buffering allows connected displays to remain controlled through the selected path. EDID replication supports systems that require consistent display identity information across switched sources. Deployment should be limited to compatible legacy installations unless a new design has received formal manufacturer guidance, because the part is not recommended for new designs.
Recomendado
Digital Signage Display Hub
A digital-signage hub with several media sources can use the ADV3002XSTZ to route one HDMI/DVI input to a display while preserving DDC, CEC, and EDID behavior. The four-input architecture is useful where source selection changes according to operating mode, and integrated equalization supports links involving longer cable runs. EDID replication is especially relevant when downstream display identification must remain consistent. The implementation should maintain the original 80-lead LQFP land pattern and control firmware to minimize board changes, while accounting for the manufacturer's lifecycle recommendation in long-term maintenance plans.
Recomendado
Video Wall and Presentation Systems
The ADV3002XSTZ can be incorporated into a presentation or video-wall controller that must select among multiple computer or media-source HDMI/DVI connections. Equalized TMDS inputs assist with cable-loss control, while DDC/CEC buffering supports display-side communication and EDID replication helps maintain a consistent identity across inputs. Because the ADV3002 provides one switched destination rather than a multi-output matrix, the design may require additional routing infrastructure for larger installations. Existing boards using the established 80-lead footprint benefit from component continuity during repairs and lifecycle extensions.

Notas de diseño
Treat equalization as part of a complete channel design rather than an automatic guarantee of long-cable operation. Validate the source, connector, cable type and length, transition-minimized differential signaling data rate, PCB routing, switch, and receiving display together. Use the manufacturer pin and application information to identify every high-speed differential pair and preserve the intended reference-plane arrangement. This prevents a long cable or poor connector from masking the switch's equalization capability.
For legacy board repair, preserve the 80-lead LQFP footprint, pad geometry, and component orientation before fitting ADV3002XSTZ. Confirm the complete pin-description table in the manufacturer documentation because the high-speed lanes, power connections, ground pins, DDC, CEC, and control inputs are device-specific. Inspect for lifted pads, solder bridges, contamination, and thermal damage before replacing the IC, and verify that the PCB accommodates the lead pitch and exposed thermal construction shown in the official package drawing.
Do not substitute a generic HDMI matrix or mux solely because it also offers four inputs. Require an 80-lead pin-to-pin match and verify power rails, control logic, DDC and CEC directionality, EDID handling, equalization, and supported HDMI behavior. ADV3002XSTZ and ADV3002XSTZ-RL are ordering variants of the same family, not evidence that unrelated HDMI switches are drop-in replacements. Record the approved part number and suffix separately to avoid unintended purchasing or assembly substitutions.
Use the manufacturer's recommended decoupling and supply-routing requirements when repairing or integrating the device. Place power and ground connections according to the official datasheet and PCB guidance, and inspect the original board for electrolytic leakage, cracked solder joints, or contaminated power planes. Because a failed switch can be caused by an upstream supply defect, replacing the IC without checking the surrounding rail condition may lead to repeated failure. Confirm operating limits and test points against the manufacturer documentation before energizing the assembly.
