ADV3228ACPZ - 750MHz 8x8 Crosspoint Switch | Analog Devices
部品番号: ADV3228ACPZ ✓ 生産中ADV3228ACPZ 概要
An analog crosspoint switch is an integrated routing matrix that connects any selected input to any selected output while providing controlled impedance and gain. The ADV3228 combines eight high-speed, nonblocking switch arrays, buffered inputs, programmable high-impedance outputs, and eight output amplifiers with +1 gain. Its architecture makes it useful where a board must route multiple wideband channels without relying on discrete relays or lossy passive networks. The device is specifically identified as pin-compatible and functionally equivalent to the AD8108 and AD8109, and is drop-in compatible with the ADV3224 and ADV3225 16 × 8 array family according to the manufacturer product-page information.
Key performance features include a 750 MHz −3 dB large-signal bandwidth for ADV3228, 2500 V/µs slew rate, operation from ±5 V supplies, and the ability to drive 150 Ω loads. Programmable high-impedance outputs allow selected output channels to be placed in a high-impedance state, which can support paralleling or system-level routing strategies. The buffered-input architecture and output amplifiers provide a complete routing solution rather than requiring external signal-conditioning stages.
The ADV3228ACPZ is suitable for video routing, telecommunications equipment, broadcast systems, high-speed test equipment, and professional audio or instrumentation designs. The 72-lead LFCSP-VQ package supports dense PCB layouts, while the exposed-pad construction provides an important thermal path for power dissipation. Designers should pay close attention to supply bypassing, controlled-impedance routing, thermal-pad layout, and the datasheet’s recommended input and output termination networks.
When selecting a replacement, verify the exact ACPZ package, pinout, gain configuration, supply arrangement, and bandwidth requirements. The ADV3229 has +2 gain rather than the ADV3228’s +1 gain, while ADV3224 and ADV3225 belong to the related 16 × 8 family. For existing designs that require the ADV3228’s exact gain and footprint, the manufacturer-documented compatible parts provide the safest replacement path. This page combines verified manufacturer and distributor information with practical design guidance and a structured comparison of documented alternatives.

主な用途
ADV3228ACPZ の用途: 6 件s: Telecommunications Signal Routing, Professional Video Switching, Broadcast and Studio Routing, High-Speed Test and Measurement, Industrial Instrumentation, Analog Signal Test and Switching.
Telecommunications Signal Routing
The ADV3228ACPZ fits telecommunications routing cabinets where several wideband channels must be switched without introducing excessive attenuation or reflections. Its 750 MHz −3 dB large-signal bandwidth and 2500 V/µs slew rate provide ample margin for high-frequency analog paths, while the nonblocking 8 × 8 architecture permits multiple simultaneous routes. The device is used between ±5 V supplies and includes buffered inputs, +1 output amplifiers, and 150 Ω load drive capability. In implementation, controlled-impedance routing, close decoupling, and careful exposed-pad grounding are essential for preserving edge rate and minimizing crosstalk.
おすすめ
Professional Video Switching
The ADV3228ACPZ is appropriate for professional video routing systems requiring eight reusable inputs and eight selectable outputs. Its 750 MHz bandwidth supports high-definition and related wideband video signals, while the buffered-input architecture reduces the need for separate line-driver stages. The programmable high-impedance outputs add flexibility for bus-style or expandable routing arrangements. The crosspoint is normally placed on a controlled-impedance board with short connections to source and destination circuits, and its ±5 V supplies must be filtered close to the package. Engineers should verify source impedance, termination, video bandwidth, and permissible loading against the datasheet.
おすすめ
Broadcast and Studio Routing
A broadcast studio router can use the ADV3228ACPZ to distribute high-bandwidth analog channels among processing chains, monitors, and transmission equipment. Its nonblocking 8 × 8 matrix allows simultaneous routing without mechanical switching delay, and the eight +1 output amplifiers provide a consistent interface to downstream stages. The 2500 V/µs slew rate supports rapid edge transitions, while programmable output impedance can support flexible test or parallel-output arrangements. Practical implementation requires low-noise ±5 V rails, short supply bypass paths, solid thermal-pad grounding, and controlled-impedance routing to avoid reflections across studio cable interconnects.
おすすめ
High-Speed Test and Measurement
The ADV3228ACPZ is well suited to high-speed analog test systems that need to route several channels among instruments, fixtures, or DUTs. The 750 MHz −3 dB bandwidth allows the crosspoint to handle substantially faster signals than conventional video switches, while the nonblocking architecture reduces test-cycle delays. Programmable high-impedance outputs can isolate channels when required, and the buffered inputs simplify source interfacing. For bench and factory equipment, designers should use short controlled-impedance traces, carefully placed bypass capacitors, and a robust ground and exposed-pad plan so the device maintains predictable insertion loss and isolation behavior.
おすすめ
Industrial Instrumentation
The ADV3228ACPZ can serve as a wideband analog routing element in industrial instrumentation that switches sensor, excitation, or diagnostic signals among measurement channels. Its nonblocking 8 × 8 organization supports flexible channel reassignment, and the +1 output gain preserves signal levels when additional amplification is not required. The 150 Ω load capability and buffered inputs make the device suitable for moderate-impedance analog networks, provided the source and destination impedances are checked. In deployed equipment, thermal management, supply isolation, and guarding against ESD or surge events are as important as high-speed layout because industrial ports may connect to external cabling.
おすすめ
Analog Signal Test and Switching
The ADV3228ACPZ supports analog signal test matrices where multiple source channels must be connected to measurement paths with predictable gain and bandwidth. Its 750 MHz large-signal bandwidth and 2500 V/µs slew rate provide useful margin when evaluating high-speed buffers, converters, or video stages. Because the device includes eight output amplifiers with +1 gain, it can function as a complete routing stage rather than a bare switch matrix. The tradeoff is that its ±5 V dual supply increases board complexity compared with single-supply multiplexers. Confirm source impedance, output loading, thermal rise, and signal-return paths against the manufacturer datasheet.

設計ノート
Treat all eight analog inputs and outputs as high-speed controlled-impedance paths. Keep traces short, remove unnecessary vias and stubs, and use a continuous ground reference beneath the routing layer. The 750 MHz bandwidth and 2500 V/µs slew rate make interconnect reflection control essential. Use the manufacturer's evaluation-board layout and reference-plane arrangement as the starting point rather than adapting a generic low-speed switch layout.
The ADV3228ACPZ requires ±5 V supplies, so both positive and negative rails need low-impedance return paths. Place the datasheet-recommended bypass capacitors immediately adjacent to the relevant supply and ground pins, and keep the exposed pad electrically connected to the appropriate ground plane. Verify rail sequencing and noise at the package rather than only at the regulator. Because power consumption is documented as 0.5 W, provide adequate copper area for heat spreading.
The 72-LFCSP-VQ package relies on its exposed pad for heat transfer. Follow the manufacturer land pattern, including the number and size of thermal vias, and avoid placing thermal breaks beneath the pad. Estimated power dissipation is 0.5 W under the manufacturer's documented operating condition; this is a datasheet figure rather than an arithmetic estimate. Validate the final junction-temperature margin in the intended enclosure and ambient environment.
Do not substitute ADV3229ACPZ without checking signal gain: its output amplifiers provide +2 gain rather than the ADV3228's +1 gain. Likewise, ADV3224ACPZ and ADV3225ACPZ are associated with the 16 × 8 family, so verify routing architecture and control behavior. The AD8108 and AD8109 are described as functionally equivalent in pinout, but exact supply, control, and performance equivalence should still be confirmed against the manufacturer data before a production change.
