ADV3002BSTZ - 4:1 HDMI/DVI Switch with EDID | Analog Devices
MPN: ADV3002BSTZ ✗ जीवन की समाप्तिADV3002BSTZ अवलोकन
An HDMI/DVI link switch is a signal-routing interface IC within the broader video-processing and interface-controller hierarchy. The ADV3002 combines the active video-link path with the auxiliary communication paths required by HDMI equipment. Equalization on the TMDS inputs helps recover signals traveling through longer cables, while DDC and CEC buffering isolates auxiliary traffic from the main video connection.
The primary feature set includes four inputs, one output, integrated input equalization, bidirectional DDC-bus buffering, CEC-line buffering with integrated pull-up resistors, and EDID replication. The device supports HDMI 1.4a according to the product listing, while the family documentation also references HDMI 1.3a. Input pins provide ±8 kV ESD protection, adding a useful protection layer for externally connected equipment.
ADV3002BSTZ is controlled through an I2C-compatible serial interface. In a typical receiver, source detection, switch control, EDID handling, and auxiliary-line communication are combined into one device instead of requiring separate discrete switches and buffers. The equalized inputs make the switch applicable where multiple source cables vary in length or where source-to-display distance makes clean signal recovery important.
Typical applications include television and display input selection, HDMI extenders and distribution equipment, professional video systems, set-top boxes, projectors, and multi-source presentation equipment. EDID replication supports source-side display identification, while DDC and CEC buffering allows connected equipment to continue exchanging control data through the selected link.
PCB implementation requires care around high-speed TMDS and auxiliary signals. The manufacturer datasheet recommends short CEC and DDC traces, direct connections from bypass-capacitor landing pads to supply pins, and clearance beneath auxiliary traces when the adjacent layer can act as a reference plane. These layout practices reduce parasitic inductance and unwanted coupling.
This product page combines the manufacturer product information, technical datasheet guidance, drop-in replacement assessment, application use cases, and implementation notes. It highlights why the ADV3002BSTZ fits multi-input HDMI/DVI equipment while keeping sourcing, lifecycle, packaging, and design decisions in one engineering-focused reference.

सामान्य अनुप्रयोग
ADV3002BSTZ के लिए उपयुक्त है 6 अनुप्रयोगs: Multi-Source Television Input Switching, Professional Video Presentation Equipment, HDMI Extender and Distribution Equipment, Set-Top Box and Media-Center Design, Projector and Large-Display Input Control, Digital Signage and Multi-Source Kiosk.
Multi-Source Television Input Switching
The ADV3002BSTZ fits television and display designs that must select one of four HDMI or DVI sources for a shared output panel. Its four equalized TMDS inputs help preserve signal integrity when source cables have different lengths, while DDC and CEC buffering keeps auxiliary communication associated with the selected path. EDID replication can present the downstream display information to the active source. The single-output architecture simplifies the television chassis while reducing the need for separate video switches, auxiliary buffers, and EDID-routing circuitry. Engineers should verify connector data rates and source-device compatibility during system testing.
अनुशंसित
Professional Video Presentation Equipment
Conference-room and presentation systems frequently connect computers, media players, cameras, and other sources to a projector or display. The ADV3002BSTZ provides a centralized 4:1 selection point, with integrated equalization intended to assist recovery of TMDS signals over longer cable runs. Bidirectional DDC and CEC buffers allow source and sink equipment to communicate through the selected route, and EDID replication helps source software resolve the intended display characteristics. Because four physical inputs still require careful isolation and return-path management, connector layout and chassis grounding remain important.
अनुशंसित
HDMI Extender and Distribution Equipment
The ADV3002BSTZ is suitable for the input-selection stage of an extender or distribution product where several source cables feed one processing or transmission chain. Its equalized TMDS inputs target signal-degradation problems encountered with long runs, while the isolated DDC and CEC paths preserve auxiliary communication between the source and remote sink. EDID replication supports a transmitter, extender, or display chain that must emulate the downstream display identity. Designers should still evaluate total link budget, including source strength, cable category, connector losses, and the performance of the downstream HDMI receiver.
अनुशंसित
Set-Top Box and Media-Center Design
A media-center or set-top-box design can use the ADV3002BSTZ when it must accept four external HDMI/DVI sources and present one route internally or to a display. Integrated equalization makes the device useful when consumer cable lengths vary, while DDC and CEC buffering lets the source exchange display information and control commands through the selected input. EDID replication can improve source compatibility by returning the intended display identity. Implementation should keep auxiliary traces compact, provide stable bypass capacitance, and validate hot-plug behavior against every source device planned for the product.
अनुशंसित
Projector and Large-Display Input Control
Projectors, large displays, and interactive panels often accept several source types while requiring a single internal video route. The ADV3002BSTZ consolidates four equalized video inputs, auxiliary buffering, and EDID handling into one 80-lead LQFP device. Equalization supports recovery from variable source-to-panel cable lengths, and CEC/DVC-style control paths remain connected through the selected route. In high-speed video products, connector-to-chip routing should remain short where possible, return vias should be distributed through the signal region, and the PCB stackup should be reviewed against the manufacturer layout guidance.
अनुशंसित
Digital Signage and Multi-Source Kiosk
Digital-signage kiosks, retail displays, and control-room panels may combine live video from several external sources with an internal playback channel. The ADV3002BSTZ can place four externally connected HDMI/DVI inputs behind one switched output, using equalized inputs to improve tolerance of variable cable lengths. DDC and CEC buffering keeps auxiliary communication active on the selected route, while EDID replication allows the source to recognize the intended downstream display. For reliable deployment, test cold-start sequences, hot-plug events, source timeout behavior, and system-level ground-noise conditions rather than testing only nominal video playback.

डिज़ाइन नोट्स
Route the TMDS pairs as controlled-impedance differential connections and minimize discontinuities between connectors, protection structures, and the ADV3002BSTZ. Place the equalized inputs close to the device where practical, and use a stackup that supports the required data rate. Keep the DDC and CEC paths short because long auxiliary traces can increase susceptibility to coupling from adjacent high-speed video signals.
Place bypass capacitors beside the relevant supply pins and connect their landing pads directly to the pins with minimal trace length. The manufacturer datasheet emphasizes reducing the inductance between capacitor pads, vias, and power connections. Use multiple nearby return vias for high-speed and auxiliary signals, and check the complete return path through every layer change before releasing the layout.
Evaluate equalization performance at the longest supported cable length, not only with short bench leads. Include source output strength, cable loss, connector transitions, input protection structures, and the downstream receiver in the test matrix. Because the device is not recommended for new designs, confirm that the complete source-to-sink link remains compliant before using it in a new production platform.
Do not treat the ADP8860 as a substitute: it is a DC-DC converter rather than an HDMI/DVI switch. A genuine replacement must preserve the 80-lead LQFP footprint, pin-to-pin functions, TMDS routing, auxiliary-line behavior, and EDID implementation. Obtain an official lifecycle or replacement recommendation from the manufacturer rather than substituting based only on the number of inputs or package dimensions.
