ADV7623BSTZ-P - 4-Input HDMI Transceiver | Analog Devices
MPN: ADV7623BSTZ-P ✓ AktifADV7623BSTZ-P Ringkasan
An HDMI transceiver is an interface semiconductor that converts digital video and audio streams between HDMI connectors and an internal digital bus. The ADV7623BSTZ-P sits within the interface IC hierarchy and supports source switching, sink processing, audio extraction, audio insertion, and audio return channel functions. This consolidation can reduce the number of separate interface devices required in a switching or repeater design.
Key capabilities include four multiplexed HDMI inputs, one HDMI output, an audio output port, a dedicated audio input port, and an audio return channel receiver. The device supports HDMI 1.4a, 3D television signaling, content type bits, and advanced high bit rate audio formats. Its control interface uses a 2-wire, I2C-compatible serial bus for configuration by an external master controller.
The ADV7623BSTZ-P also provides HDCP repeater functions supported by Analog Devices software libraries and drivers. This feature set is relevant to systems that route protected high-definition multimedia content between source and sink equipment. The integrated audio paths allow audio to be extracted from or inserted into an HDMI stream without requiring a separate format conversion device in many system architectures.
Typical uses include professional video routers, presentation systems, digital audio/video matrices, home-theater equipment, and broadcast infrastructure. The four-input architecture is especially useful when a system must select among several HDMI sources while maintaining one transmitter output. The dedicated audio paths can support extraction of digital audio for a separate sound system or insertion of audio into an outgoing video stream.
When laying out a board, follow the Analog Devices ADV7623 datasheet pin description, exposed-pad requirements, reference circuit, and recommended decoupling values exactly. The 5 V supply rail requires local high-frequency bypass capacitance, while HDMI routing must be controlled to minimize signal degradation. Firmware and HDCP repeater support should be evaluated as part of the complete system design rather than treated as an automatic capability of the silicon alone.
This product data combines the manufacturer feature description, package and ordering information, interface capabilities, sourcing guidance, and design-focused application analysis. It also distinguishes true drop-in replacements from related HDMI devices with different input counts, package details, or feature sets, helping engineers make a technically defensible selection without assuming that similar functionality guarantees PCB compatibility.

Aplikasi Biasa
ADV7623BSTZ-P patut untuk 6 aplikasis: Professional Four-Source HDMI Router, Digital Audio and Video Matrix, Home-Theater HDMI Switching Hub, Presentation and Conference-Room Switching, Broadcast and Studio Video Routing, Digital Audio Extraction and Return-Path System.
Professional Four-Source HDMI Router
The ADV7623BSTZ-P fits a professional video router that must select among four HDMI sources and drive one downstream display or processing system. Its four integrated receiver inputs remove the need to place four unrelated receiver blocks beside a separate four-to-one HDMI switch. The single transmitter output and 2-wire I2C-compatible control interface allow an external controller to change ports and manage the device consistently. The design must provide a stable 5 V rail and follow the manufacturer’s reference layout for the 144-LQFP package. Firmware qualification is also important because HDCP repeater behavior depends on the complete Analog Devices library and driver stack, not only on basic HDMI routing.

Digital Audio and Video Matrix
The ADV7623BSTZ-P is useful in a digital audio/video matrix where incoming HDMI streams must be selected, audio must be extracted, and a programmable outgoing stream must be created. Its dedicated digital audio output supports extraction of the selected stream’s audio, while the dedicated digital audio input allows another audio source to be inserted before transmission. This arrangement can reduce external conversion and switching blocks when the system already uses HDMI as its internal transport format. The 5 V supply requirement and exposed-pad package make power delivery and thermal design explicit parts of the layout. Firmware should be tested against the desired audio formats, including compressed high bit rate audio and the audio return channel path.

Home-Theater HDMI Switching Hub
The ADV7623BSTZ-P can serve as the central switching element in a home-theater hub that accepts four source devices and presents one selected signal to an amplifier, television, or AV processor. Its integrated digital audio paths help separate selected audio from video for downstream processing while retaining the option to insert local audio into the outgoing HDMI stream. HDMI 1.4a support, 3D television signaling, and content type bits make the device relevant to systems that must preserve modern HDMI metadata. Because the transceiver combines active high-speed HDMI links with control and audio signals, the board layout should closely follow the Analog Devices reference design and include local bypass capacitance on the 5 V rail.

Presentation and Conference-Room Switching
The ADV7623BSTZ-P supports presentation equipment that connects a laptop, media player, conferencing endpoint, and auxiliary source while switching among them for a shared display. Four receiver inputs align with common room-control requirements, and the I2C-compatible control interface allows a room controller to perform input selection and configuration. The dedicated audio output can route selected digital audio to a sound system, while the dedicated audio input can provide a local presentation source. HDMI 1.4a and 3D television support can preserve suitable high-definition source features. Product qualification should verify the source formats, HDCP policy, control firmware, and any room-specific CEC behavior required by the installation.
Disebarkan
Broadcast and Studio Video Routing
The ADV7623BSTZ-P can participate in broadcast or studio infrastructure where several production sources feed a controlled processing chain through HDMI. The four-to-one receiver and transmitter arrangement supports centralized source selection, while integrated audio extraction permits selected digital audio to be handed to separate studio audio equipment. HDCP repeater functionality is relevant when protected content must pass through repeater systems, although successful deployment requires the appropriate tested software libraries and drivers. The 5 V, 144-LQFP implementation should be evaluated for connector proximity, return-path routing, supply integrity, and thermal performance. Signal-integrity testing remains necessary because cable length, connector choice, and source-device implementations can materially affect a complete HDMI link.
Disebarkan
Digital Audio Extraction and Return-Path System
The ADV7623BSTZ-P fits systems that need to extract audio from one of four HDMI inputs and then return or insert audio through a dedicated path. The dedicated digital audio output provides access to the selected stream’s audio without relying solely on the HDMI connector, while the audio input supports insertion into an outgoing stream. The integrated audio return channel receiver simplifies upstream audio return handling in compatible equipment. Designers should account for supported audio formats, including compressed high bit rate audio and SACD via DSD, when defining clocking and conversion requirements. Board implementation must follow the manufacturer’s exposed-pad and reference-circuit requirements while keeping the 5 V supply path short and adequately bypassed.

Catatan Desain
Use the Analog Devices ADV7623 datasheet footprint and reference layout without substituting a generic 144-LQFP land pattern. Position input and output bypass capacitors close to their associated supply pins, connect the exposed pad according to the manufacturer’s thermal guidance, and keep the 5 V return path compact. Confirm connector and HDMI trace geometry against the reference design because transitions and return-path discontinuities can affect signal integrity.
Design the 5 V rail for both transceiver operation and connector-adjacent board conditions. Follow the datasheet’s recommended capacitor network and power-up behavior, and place high-frequency bypass capacitance at the device supply pins. Verify startup sequencing and voltage tolerance in the complete system, particularly when the HDMI inputs remain connected to sources that are powered at different times.
Treat each HDMI input and output as a controlled-impedance channel rather than an ordinary digital bus. Follow the manufacturer’s connector, trace, and return-path guidance, minimize unnecessary stubs, and test representative cable lengths and source devices. Validate the audio input and output routing alongside the HDMI links because clocking, source format differences, and firmware configuration can affect end-to-end audio behavior.
Do not equate partial HDMI functional overlap with drop-in compatibility. The ADV7612 and ADV7611 have not been confirmed as 144-LQFP, four-input, one-output pin-compatible replacements for the ADV7623BSTZ-P. Also verify the complete Analog Devices repeater software, drivers, source formats, HDCP requirements, and control protocol before committing to a production design.
