ADV3225ACPZ - 750 MHz 16x8 Analog Crosspoint | Analog Devices
MPN: ADV3225ACPZ ✓ ActiveADV3225ACPZ Overview
An analog crosspoint switch is a semiconductor matrix that routes analog signals between multiple inputs and outputs. It belongs to the analog switch and multiplexer hierarchy, interface IC category, and broader signal-routing semiconductor family. Unlike a mechanical relay or multiplexer, the ADV3225ACPZ can maintain multiple signal paths concurrently, making it useful when a system requires flexible routing without interrupted paths during control changes.
Key features include a 16 × 8 switch matrix, nonblocking operation, buffered inputs, programmable high-impedance outputs, and eight +2-gain output amplifiers. The crosspoint can drive 150 Ω loads and operates from ±5 V supplies. Its stated power consumption is 0.5 W. The combination of 750 MHz bandwidth and greater than 2500 V/µs slew rate supports high-frequency analog signals whose fidelity must be preserved through routing.
The ADV3225ACPZ is positioned as a pinout-compatible and functionally equivalent alternative to the AD8110 and AD8111 families. The manufacturer also identifies compatibility with the ADV3228 and ADV3229 8 × 8 arrays. This makes the device relevant to broadcast, video-routing, telecommunications, and test-equipment designs in which a compact, high-speed analog routing matrix is required. Its buffered architecture allows external signals to be routed without placing additional gain stages at every destination.
Typical applications include video production and broadcast routing, telecommunications line and channel routing, multimedia distribution, A/V equipment, and high-speed test systems. Eight independently controllable output amplifiers can provide fixed +2 gain, while programmable output high-impedance states support parallel crosspoint outputs when higher output drive is required. The 16 × 8 architecture offers more source choices than the related 8 × 8 devices.
The primary design consideration is the ±5 V supply requirement and the need to preserve high-frequency signal integrity. Supply decoupling should be placed close to the device, and routing should minimize trace lengths and discontinuities on this bandwidth demanding package. Designers should also review output loading and control sequencing because the 150 Ω load capability and parallel-output behavior are central to maintaining signal amplitude and bandwidth.
This page combines the manufacturer's matrix architecture and AC-performance specifications with practical routing, decoupling, and output-loading guidance. It also distinguishes the ADV3225 from related gain and matrix-size options and explains the verified compatibility paths for legacy AD8110 and AD8111 designs.

Typical Applications
ADV3225ACPZ is suitable for 6 applications: Broadcast Video Routing, Telecommunications Channel Routing, Professional Audio Distribution, Video Test Equipment, Multimedia Signal Routing, High-Speed Analog Matrix Test.
Broadcast Video Routing
The ADV3225ACPZ fits broadcast video routers that require many source signals to be distributed among several destinations without blocking active routes. Its 16 × 8 nonblocking matrix offers eight independently controlled outputs, while the greater-than-750 MHz bandwidth and greater-than-2500 V/µs slew rate preserve fast video edges. The eight +2-gain output amplifiers can compensate for distribution loss before signals reach downstream receivers. Board designers should terminate inputs correctly, preserve short return paths, and verify that the selected video format remains within the device's operating bandwidth and allowable jitter budget.
Recommended
Telecommunications Channel Routing
ADV3225ACPZ can serve as the central analog routing matrix in telecommunications equipment where multiple channels must be switched among shared processing paths. Sixteen buffered inputs and eight nonblocking outputs support flexible channel reassignment, while the programmable high-impedance output state permits controlled paralleling where the system requires additional drive. Operation from ±5 V and a stated 0.5 W consumption simplify system-level power budgeting, although designers should preserve the ±5 V sequencing required by the device. Signal-loss and return-loss targets should be checked in the final backplane, connector, and cable configuration.
Recommended
Professional Audio Distribution
The ADV3225ACPZ is applicable to professional audio distribution and switching systems requiring a high-bandwidth analog matrix. Its 16 × 8 architecture allows up to sixteen sources to be assigned among eight outputs, while the nonblocking behavior supports changes without forcing every connected path into a serial selection. The +2 output gain can provide level restoration after passive distribution losses, and the 150 Ω load capability is relevant to balanced audio routing networks. Engineers should still validate output amplitude, distortion, channel isolation, and stability against the complete analog path rather than relying only on bandwidth specifications.
Recommended
Video Test Equipment
ADV3225ACPZ is well suited to video test equipment that must route several source patterns to instruments or display paths for characterization. The matrix offers 16 selectable inputs and eight outputs with greater-than-750 MHz bandwidth, supporting edge-fast test signals without a sequential multiplexer limitation. Its buffered inputs help isolate upstream sources from downstream loading, and programmable output high-impedance states provide flexibility when combining outputs. Laboratory designs should use controlled 150 Ω-compatible termination, account for connector and cable loss, and verify gain accuracy at the frequencies relevant to the intended video test standard.
Recommended
Multimedia Signal Routing
The ADV3225ACPZ can support multimedia systems that route baseband or composite analog signals from several sources into processing or display channels. Its nonblocking 16 × 8 organization allows concurrent signal paths, which is useful for production equipment that must maintain monitoring connections while changing program feeds. Eight +2-gain output amplifiers provide headroom for passive loss, and the programmable high-impedance outputs allow tailored output configurations. For consumer-facing equipment, system designers should validate synchronization behavior, channel isolation, and signal integrity over the complete connector and cable path before treating the routing matrix as transparent.
Recommended
High-Speed Analog Matrix Test
ADV3225ACPZ is useful in production and validation fixtures for testing high-speed analog routing assemblies and downstream channels. By assigning one of sixteen inputs to each of eight outputs, a fixture can automate stimulus selection while retaining concurrent monitoring paths. The greater-than-2500 V/µs slew rate and greater-than-750 MHz bandwidth support fast-edge evaluation, while the +2 output gain helps compensate for fixture attenuation. Layout is critical: use short controlled-impedance routes, adequate supply decoupling, stable reference planes, and calibrated terminations so fixture artifacts are not mistaken for crosspoint performance.

Key Differentiators
- Twice the input-channel count of the 8 × 8 alternatives (vs ADV3228ACPZ)
- Higher fixed output gain for distribution loss compensation (vs ADV3224ACPZ)
- Full 16 × 8 routing with manufacturer-defined compatibility (vs ADV3229ACPZ)
Design Notes
Route analog inputs and outputs as short, controlled-impedance traces on a continuous reference plane. The greater-than-750 MHz bandwidth makes connector launches, via stubs, and abrupt impedance changes significant. Follow the land pattern and exposed-pad connection guidance in the official Analog Devices package drawing, and place input and output decoupling close to their associated pins.
The device requires ±5 V supplies and has a stated power consumption of 0.5 W. Provide local high-frequency bypassing at each supply connection and keep the positive and negative return paths short. Use the manufacturer's recommended supply arrangement to avoid common-impedance disturbance on the analog outputs, and verify startup and shutdown sequencing for every external source and load connected to the matrix.
Treat the 150 Ω load rating as a system constraint rather than a target impedance. Include cable, connector, termination, and receiver loading in the complete path, and measure amplitude, bandwidth, crosstalk, and return loss at the board interface. The +2 output gain changes downstream signal levels by 6 dB, so gain budgeting must include both the gain stage and loss introduced by external routing.
Do not treat the ADV3228 and ADV3229 8 × 8 matrices as exact functional replacements for the ADV3225 16 × 8 matrix. Although the manufacturer identifies compatible family relationships, the input count is reduced by 50%. Also confirm whether a required replacement needs +1 or +2 output gain, and verify the exact 72-lead package pin mapping before committing a drop-in substitution.
Compliance Information
The ADV3225ACPZ listing identifies the component as RoHS compliant and lead free. No additional REACH, AEC-Q100, halogen-free, or conflict-minerals qualification is stated.
