ADV3229ACPZ - 750 MHz 8x8 Crosspoint Switch | Analog Devices
N.º da peça: ADV3229ACPZ ✓ AtivoADV3229ACPZ Visão geral
An analog crosspoint switch is a multi-input, multi-output routing matrix that connects any selected input channel to any selected output channel without requiring the inactive channels to terminate. Within the semiconductor hierarchy, the ADV3229ACPZ is an analog switch IC, an interface IC, and a signal-routing device for high-frequency video, telecommunications, broadcast, and test equipment. Its nonblocking architecture allows supported channels to remain active while other crosspoint routes change.
Key features include an 8 x 8 switch array, eight buffered inputs, eight programmable high-impedance outputs, and eight output amplifiers configured for a gain of +2. The device is specified for 150 ohm loads and low power consumption of 0.5 W. According to the Analog Devices ADV3228/ADV3229 data sheet, its large-signal bandwidth is 750 MHz and its slew rate is 2500 V/us.
Technically, the ADV3229 integrates routing switches, input buffers, output amplifiers, and output-disconnect functions into one high-speed analog matrix. The +2 output gain differentiates it from the otherwise closely related ADV3228, which uses +1 gain. The data sheet also identifies the ADV3229 as pinout- and functionally equivalent to the AD8108 and AD8109, making those legacy devices important references when evaluating board compatibility.
Typical uses include professional video routing, broadcast video distribution, telecommunications test systems, high-definition signal routing, and instrumentation requiring repeatable high-bandwidth channel selection. The buffered inputs help isolate upstream sources, while the programmable output high-impedance states allow unused outputs to be isolated from driven channels.
Designers should verify control-logic levels, exposed-pad grounding, bypass-capacitor placement, and signal-integrity performance on the target board. The 10 x 10 mm land pattern and high-speed analog routing require short connections, a continuous ground reference, and careful control of supply-return paths. Because the ADV3229 uses dual-rail supplies, both positive and negative rails must be present with appropriate decoupling.
This page consolidates manufacturer features, distributor pricing, verified source links, same-family drop-in alternatives, and practical selection guidance. It also distinguishes confirmed pin-compatible options from legacy functionally equivalent devices so engineers can verify every footprint, gain, and control requirement before redesigning an existing PCB.

Aplicações típicas
ADV3229ACPZ é adequado para 6 aplicaçãos: Professional Video Routing, Broadcast Video Distribution, Telecommunications Test Systems, High-Speed Signal Test Equipment, HD Video Matrix Switching, Instrumentation Signal Routing.
Professional Video Routing
The ADV3229ACPZ fits professional video routers because its 8 x 8 nonblocking matrix can route eight sources to eight destinations while a 750 MHz large-signal bandwidth supports high-bandwidth analog video signals. Each path includes a buffered input and a +2 gain output amplifier, which can simplify level restoration when the source cable and destination impedance introduce attenuation. The programmable high-impedance outputs are useful for isolating an inactive destination, although the 150 ohm load capability and 10 x 10 mm exposed-pad package still require careful board planning.
Recomendado
Broadcast Video Distribution
The ADV3229ACPZ is appropriate for broadcast video distribution when an eight-source, eight-destination matrix must change routes without interrupting supported channels. Its 2500 V/us slew rate helps preserve large-signal performance through the +2 output amplifiers, while the buffered inputs reduce loading interactions between source circuitry. The eight independently programmable high-impedance outputs allow unused destinations to be disconnected, a useful behavior in rack equipment where several cards may share a video distribution backplane.
Recomendado
Telecommunications Test Systems
The ADV3229ACPZ can support telecommunications test systems that need to route several analog channels into measurement and stimulus paths. Its nonblocking 8 x 8 organization allows a selected output to change connection without forcing the other supported routes into a blocked state. The +2 gain may compensate for losses within a test fixture, while the buffered inputs help preserve source drive strength. For automated systems, the main engineering checks are control timing, connector return loss, and maintaining clean +/-5 V rails.
Recomendado
High-Speed Signal Test Equipment
The ADV3229ACPZ is suitable for high-speed signal test equipment because it combines an 8 x 8 routing matrix with a 750 MHz large-signal bandwidth and 2500 V/us slew rate. Buffered inputs support repeatable connections to test sources, and the eight output amplifiers provide a consistent +2 gain. Users must account for the 150 ohm load specification, connector and cable bandwidth, and the fact that a crosspoint routes wideband analog signals without automatically correcting frequency-dependent losses introduced elsewhere in the test path.
Recomendado
HD Video Matrix Switching
The ADV3229ACPZ can serve as the routing element in an HD video matrix where eight buffered analog inputs feed eight selectable outputs. Its 750 MHz large-signal bandwidth provides substantial margin for common HD video signal paths, while the +2 gain can offset practical insertion losses from connectors, cables, and input networks. The programmable output high-impedance function allows a destination to be isolated when it is not selected, but signal-integrity validation remains essential because package parasitics and PCB routing affect real-world performance.
Recomendado
Instrumentation Signal Routing
The ADV3229ACPZ is a practical choice for instrumentation requiring programmable analog signal paths. Eight buffered inputs reduce interaction between upstream sources, and the nonblocking matrix supports flexible measurement routing. The +2 output gain is useful when a front end requires modest signal restoration, while the 150 ohm load capability allows suitable source and termination networks to be connected. Designers should use short PCB traces, a solid ground plane, and dedicated supply bypassing to preserve the advertised bandwidth and minimize crosstalk across the matrix.

Notas de projeto
Route the eight input and eight output channels as controlled, matched analog paths rather than through long shared traces around the device. Place input and output decoupling capacitors close to the corresponding supply and ground connections. The 10 x 10 mm exposed-pad package requires the manufacturer's land pattern and a low-impedance thermal and electrical ground connection; follow the data-sheet footprint rather than constructing a generic QFN pattern.
Validate insertion loss, return loss, crosstalk, and channel-to-channel skew on the assembled PCB because the specified 750 MHz bandwidth does not remove losses from connectors, cables, vias, or imperfect terminations. The device supports 150 ohm loads and includes buffered inputs, but the source impedance and termination network still form part of the complete signal path. Use the manufacturer's recommended reference layout and controlled impedance when channel-to-channel timing is critical.
The ADV3229 operates from +/-5 V supplies and has a specified power consumption of 0.5 W. Provide low-impedance connections to both rails, decouple them near the device, and keep return currents within the ground reference rather than through the analog signal traces. Confirm the voltage limits and startup behavior for the exact ADV3229ACPZ grade in the manufacturer data sheet before sequencing the positive and negative rails.
Do not select ADV3228ACPZ as an automatic substitute when the original circuit depends on the ADV3229's +2 output gain. Although the two devices are closely related, the 50% gain difference can alter signal amplitude, headroom, and downstream clipping behavior. Likewise, ADV3224ACPZ and ADV3225ACPZ use a 16 x 8 array rather than the ADV3229's 8 x 8 architecture, so confirm control mapping and unused outputs before approving either as a replacement.
Informações de conformidade
The verified source snippets do not explicitly state RoHS, REACH, lead-free, halogen-free, conflict-minerals, or AEC-Q100 status. The part is a general-purpose analog interface IC, so AEC-Q100 is recorded as not_applicable rather than qualified.
