ADV3000ASTZ - 3:1 HDMI/DVI Switch | Analog Devices
料号： ADV3000ASTZ ✓ 量产中ADV3000ASTZ 概述
An HDMI/DVI switch is a signal-routing integrated circuit that connects one video source to a display or downstream HDMI interface. The ADV3000 belongs to the broader interface IC hierarchy because it manages transition-minimized differential signaling rather than processing image data. Its input equalization compensates for cable loss, while its pre-emphasized output helps preserve high-speed edge information across board traces and external cables.
The principal features include three inputs, one output, HDMI 1.3-compliant receiver enablement, support for four TMDS channels, and a maximum TMDS data rate of 2.25 Gbps. The output can also be placed in a high-impedance state, allowing the switch to reduce power dissipation or support system arrangements in which the selected path must be disconnected. These functions suit source-selection equipment where cable reach and deterministic routing are important.
Technically, the equalized inputs and pre-emphasized outputs address complementary parts of the channel budget. Equalization restores signal amplitude degraded by copper loss, while output pre-emphasis increases the relative amplitude of transitions that represent changing data. The supported 250 Mbps to 2.25 Gbps range covers multiple digital video rates, and the 25 MHz to 225 MHz pixel-clock range determines the maximum supported timing domain. The Analog Devices product page describes the ADV3000 as the device family, while the ADV3000ASTZ ordering suffix identifies the specific package and delivery configuration.
Typical uses include multimonitor video distribution, digital presentation systems, video walls, KVM switching, rack-mounted entertainment equipment, and industrial display controllers. The part is particularly relevant where a source may be connected through a long cable and the downstream device requires one selected HDMI or DVI input. Its three-to-one topology allows several source devices to share a display connection without requiring a separate downstream input on every source.
A key design consideration is the integrity of the high-speed TMDS routing. The PCB should provide a continuous reference plane, controlled impedance, short matched routing, and minimal stubs between the device and external connectors. Power and ground connections must be decoupled according to the manufacturer's pin description, while output and input cables should be selected for the intended data rate and cable length. Signal-path changes should also be checked for data-dependent loss and connector discontinuities.
This page combines the manufacturer's functional description, the exact ADV3000ASTZ ordering and package information, interface-rate characteristics, application guidance, and design checks. It also distinguishes exact drop-in replacements from related family parts, helping engineers assess PCB compatibility, signal-integrity requirements, lifecycle considerations, and sourcing needs without relying on a generic distributor listing alone.

典型应用
ADV3000ASTZ 适用于 6 应用s: Multimonitor Video Distribution, Digital Presentation Systems, Video Wall Controller Interface, Industrial HMI and Control Panels, Rack-Mount Entertainment Equipment, KVM and Shared Display Routing.
Multimonitor Video Distribution
The ADV3000ASTZ is appropriate for a display system that must select among three HDMI or DVI sources and send one source to a downstream monitor or controller. Its three-input, one-output topology avoids adding a separate output connector to each source, while the 250 Mbps to 2.25 Gbps TMDS range supports multiple digital video rates. Equalized inputs help recover amplitude lost in source cables, and pre-emphasized outputs can preserve transition information over the downstream connection. The system designer should still verify the required pixel clock, cable length, connector type, and supported video format at each supported resolution and refresh rate.
Digital Presentation Systems
A conference-room presentation switch can use the ADV3000ASTZ to route one of three connected laptops, media players, or conferencing endpoints to a projector or room display. The single-output arrangement simplifies the room interface, while the equalized TMDS inputs are useful when a source is connected through a long cable. Operation up to a 225 MHz pixel clock permits a broad range of timing rates, but the selected source format and sink must be validated together. Firmware or control logic should also avoid unsupported hot-plug transitions and provide a stable output selection before enabling the downstream link.
Video Wall Controller Interface
The ADV3000ASTZ can serve as the source-side routing element in a video-wall controller that accepts several standardized digital video streams but drives one selected processing or display path. Its four TMDS channels per link match the channel structure of an HDMI/DVI interface, and the 2.25 Gbps maximum data rate supports higher-resolution timing than lower-rate switches. Pre-emphasized outputs are relevant because long internal or external connections can degrade transition quality. In a video wall, maintain consistent cable and connector types across all channels and validate skew, jitter, and switching behavior at the intended pixel clock.
Industrial HMI and Control Panels
Industrial human-machine interfaces can employ the ADV3000ASTZ when an operator console must select among multiple touchscreen, computer, or video-maintenance inputs. The documented -40°C to +85°C operating range supports use across a wider temperature span than typical consumer-rated components, while the 3 V to 3.6 V supply range fits common embedded logic rails. Equalization is valuable when panel wiring creates long passive cable runs. The enclosure and cable environment must nevertheless be checked for electromagnetic interference, ground potential differences, and electrostatic-discharge requirements because the device manages high-speed data rather than providing isolation.
Rack-Mount Entertainment Equipment
Professional rack-mount switchers and processors can use the ADV3000ASTZ to select among three HDMI/DVI sources for a common downstream output. The high-impedance output state is particularly useful in equipment where a disconnected path should reduce power dissipation or permit a particular routing configuration. At data rates up to 2.25 Gbps and pixel clocks up to 225 MHz, the device can address several common video standards, subject to the exact source and sink formats. Designers should account for connector launch geometry, add controlled impedance escape routing, and confirm that switching control does not produce an out-of-spec TMDS transition at the sink.
KVM and Shared Display Routing
The ADV3000ASTZ can be integrated into a KVM-style system in which a display receives a selected video link from one of three connected computers or control processors. The three-to-one arrangement supports shared-display equipment while keeping the display-side cable count fixed. Equalized inputs support cable compensation, while pre-emphasized outputs help preserve edge information on board traces and external cables. Firmware should coordinate source detection, output selection, and the high-impedance state to avoid contention. Keyboard, mouse, and USB routing remain separate functions, so system designers must use appropriate interface devices alongside this video switch.

设计说明
Treat every TMDS route as a controlled-impedance transmission line. Use a continuous reference plane, minimize stubs and layer changes, match input and output geometry, and place the TMDS connector or device in a location that avoids right-angle routing discontinuities. Validate amplitude, jitter, rise time, and crosstalk at the maximum 2.25 Gbps data rate and 225 MHz pixel clock. Equalization and pre-emphasis compensate for channel loss, but they cannot correct an incorrectly implemented PCB channel.
Follow the manufacturer package drawing and pin-description table when creating the 80-terminal LQFP land pattern and assigning pins. Place power and ground decoupling connections directly beside their associated terminals, maintain a low-impedance return path, and keep the switching and configuration traces away from the high-speed TMDS nets. Confirm terminal numbering, exposed-pad requirements, solder mask, and paste geometry with the package drawing before fabrication rather than deriving them from a generic LQFP footprint.
Do not treat ADV3002BSTZ as a confirmed pin-compatible substitute merely because it belongs to a related ADV series. Likewise, ADV3000ASTZ-RL should be checked against the manufacturer's ordering table for package, temperature grade, and delivery configuration. A valid replacement must preserve the three-input, one-output topology, terminal assignments, control behavior, supply requirements, TMDS-rate range, and high-impedance output function, followed by PCB and signal-integrity validation.
Use the manufacturer's recommended supply range of 3 V to 3.6 V and place local high-frequency bypass capacitors close to the supply and ground terminals. Keep switching current away from sensitive reference returns and confirm that the upstream regulator can support both normal signaling and output high-impedance operation. Before release, measure supply ripple at the device under worst-case source switching to ensure that power noise does not reduce TMDS eye margin.
合规信息
The available manufacturer information does not state RoHS, REACH, lead-free, halogen-free, or conflict-minerals status. AEC-Q100 qualification is not applicable because this is an HDMI/DVI interface switch rather than an automotive-qualified device.
