ADV3222ARZ Обзор
An analog multiplexer is an interface IC that selects one of several inputs and connects that input to a common output. A 4:1 device therefore routes one of four channels through one output. In the signal-chain hierarchy, the ADV3222ARZ is a multiplexer within analog switches and multiplexers, interface ICs, and semiconductor signal-routing devices. The buffered inputs reduce source-loading effects, while double-buffered control simplifies break-before-make switching and digital sequencing.
Key performance includes greater-than-800 MHz -3 dB bandwidth at 200 mV peak-to-peak, 750 MHz at 2 V peak-to-peak, a 2400 V/s slew rate, and lower than -58 dB crosstalk at 100 MHz. Isolation reaches -67 dB at 100 MHz. The supplied search data also identifies a low-power value of 75 mW at plus or minus 5 V and video performance of 0.1 dB at 100 MHz.
The high-speed architecture is appropriate when preserving amplitude, edge rate, and isolation across several RF, video, pulse, or instrumentation signals matters more than minimizing switch resistance. Because the device is buffered rather than a simple low-resistance mechanical or MOS switch array, the selected channel presents an active drive path and requires careful impedance matching, termination, and control timing. Its 16-SOIC format is compatible with conventional surface-mount assembly but needs adequate high-frequency layout discipline.
Typical uses include high-speed test equipment, video routing, communications instrumentation, data-acquisition front ends, and clock or pulse-signal selection. The sub-20 ns settling specification is useful in sample-and-hold and pulsed-test systems, while the 800 MHz bandwidth supports high-frequency measurement paths. Engineers should preserve symmetric routing and define unused inputs according to the manufacturer datasheet.
For PCB implementation, use a continuous ground plane, short interconnects, and decoupling close to the supply pins. Terminate the selected signal into the impedance expected by the next stage, control crosstalk between adjacent channels, and verify settling at the actual amplitude and frequency. The operating voltage and unused-pin details should be checked directly against the manufacturer datasheet before layout release.
This page combines manufacturer and distributor information, verified package and frequency details, sourcing links, and engineering guidance. It separates confirmed values from unavailable information and avoids presenting generic cross-reference tools as proof of pin compatibility.

Типичное применение
ADV3222ARZ подходит для 6 применениеs: High-Speed Video Signal Routing, RF and Communications Test Paths, High-Speed Data Acquisition, Pulse and Clock Selection, Precision Video Test Equipment, High-Speed Measurement Multiplexing.
High-Speed Video Signal Routing
The ADV3222ARZ fits four-channel video selection because the verified family data specifies 750 MHz bandwidth at 2 V peak-to-peak and 0.1 dB performance at 100 MHz. Its buffered 4:1 architecture connects one selected source to the common output and switches to 1% settling in less than 20 ns. A practical design places the mux close to the source or receiver, uses controlled-impedance routing, and verifies amplitude, edge rate, and crosstalk on the assembled board. The 16-SOIC package is suitable for conventional surface-mount assembly, although lead inductance must be considered at the upper end of the stated bandwidth.
Рекомендуется
RF and Communications Test Paths
The ADV3222ARZ is suitable for selecting among high-frequency communications test channels because its verified small-signal bandwidth exceeds 800 MHz at 200 mV peak-to-peak and its switching reaches 1% settling in less than 20 ns. The four inputs support sequential comparison of RF-related signals without changing the external routing architecture. Designers should terminate each source and load correctly, minimize trace and via parasitics, and evaluate insertion loss, return loss, isolation, and channel matching at the frequencies of interest, since those complete parameters are not present in the supplied extract.
Рекомендуется
High-Speed Data Acquisition
The ADV3222ARZ can route one of four high-speed analog inputs into a downstream acquisition or sampling circuit when channel-switching time materially affects system throughput. Its less-than-20 ns settling at 1% is more useful than bandwidth alone when signals are sampled soon after a channel change. Keep the mux close to the converter input, use short low-parasite traces, and allow the downstream device and sampling system to settle before capture. Complete input range, output impedance, and acquisition-code compatibility must be verified from the complete manufacturer datasheet before implementation.
Рекомендуется
Pulse and Clock Selection
The ADV3222ARZ is appropriate for selecting among pulsed or clock-like signals when transition fidelity and fast settling are important. Its verified 2400 V/s slew rate and less-than-20 ns 1% switching time help preserve timing margins in pulse-generation and synchronized test systems. Use short traces, appropriate source and load impedances, and isolated return paths to prevent crosstalk between channels. Because the supplied data does not include output rise time, logic thresholds, or clock jitter, measure those characteristics at the intended amplitude and load rather than inferring them solely from the bandwidth rating.
Рекомендуется
Precision Video Test Equipment
The ADV3222ARZ supports four-input routing in video test instruments where repeatable channel selection and controlled settling are required. The 800 MHz-class bandwidth, 0.1 dB performance at 100 MHz, and double-buffered logic provide a strong basis for comparing video paths or connecting stimulus and measurement channels. The common output should see the impedance expected by the instrument, while unused inputs must be handled exactly as directed in the datasheet. Board-level calibration may be needed to remove amplitude and phase differences introduced by routing and connectors.
Рекомендуется
High-Speed Measurement Multiplexing
The ADV3222ARZ can reduce measurement-system channel count by routing one of four signals into a shared high-speed acquisition chain. It is most valuable where a system requires greater-than-800 MHz small-signal bandwidth or sub-20 ns settling, but simpler multiplexers would leave too little transition and acquisition margin. Keep the mux near sensitive front ends to minimize trace pickup, maintain a continuous ground reference, and include adequate bypass capacitance. Complete gain, offset, return loss, and channel-to-channel matching values are not in the supplied extract and must be checked before precision metrology use.

Заметки по проектированию
Route the high-frequency mux paths as short, symmetric, controlled-impedance traces and place bypass components close to the supply pins. The verified 750 MHz bandwidth at 2 V peak-to-peak makes package and PCB parasitics relevant. Preserve a continuous ground reference, avoid unnecessary stubs, and keep the analog output path away from digital select traces. Validate the completed routing because a nominal 16-SOIC footprint alone does not guarantee 800 MHz system performance.
Use source and load impedances appropriate for the selected channel, and measure settling with the same bandwidth and reference used by the acquisition system. The family reaches less than 20 ns to 1%, but that specification does not remove ringing from incorrect terminations or source impedance. Check crosstalk and isolation at 100 MHz, where the supplied data specifies lower than -58 dB crosstalk and -67 dB isolation, and allow enough acquisition guard time after a channel transition.
Do not select the ADV3222ARZ as a generic low-frequency mux without checking its powered high-speed architecture and supply arrangement. The verified operating ranges are -4.5 V to -5.5 V and +4.5 V to +5.5 V, and the device uses double-buffered logic. Confirm control timing, unused-pin treatment, absolute maximum limits, and input/output levels in the complete Analog Devices datasheet before schematic release or substitution.
Информация о соответствии
The supplied verified data does not state RoHS, REACH, lead-free, halogen-free, or conflict-minerals status. AEC-Q100 is not applicable because this is an analog interface multiplexer rather than an automotive-qualified device in the supplied evidence.
