ADV3205JSTZ - 60 MHz Buffered Analog Crosspoint | Analog Devices
部品番号: ADV3205JSTZ ✓ 生産中ADV3205JSTZ 概要
An analog crosspoint switch is a semiconductor routing matrix that connects one source signal to one destination while buffering the selected path. Unlike an unbuffered passive matrix, the ADV3205 provides active buffering, which can reduce loading effects and support controlled signal transfer between source and destination stages. In a broader equipment hierarchy, it belongs to the analog switch and signal-routing category, within interface and video-routing applications. Its buffered architecture is particularly relevant when the routed signal must remain useful across multiple video-processing stages.
The principal verified performance characteristics are 60 MHz signal bandwidth, +2 dB gain, a 16 × 16 matrix, operation from ±5 V, and channel switching time below 60 ns with 0.1% settling. The switching-time figure indicates how quickly the device changes routing state, while the settling specification describes the time required for the output to reach the specified accuracy. The low settling behavior can be valuable in measurement, broadcast, test-equipment, and video-processing systems where a new source must be selected quickly.
The ADV3205 also includes ground and power pins around the inputs and outputs to provide shielding between signal paths. This arrangement is intended to improve isolation for demanding analog-routing applications and can reduce coupling between adjacent channels when the PCB layout and grounding system are implemented carefully. The manufacturer identifies the device as recommended for new designs and markets it for video applications, so it is positioned as an active analog-routing solution rather than a simple discrete switch.
Typical uses include professional video routing, camera and monitor signal distribution, laboratory test systems, broadcast equipment, and industrial video control. In these systems, the matrix can route one of multiple source signals to a processing chain or measurement instrument. The active buffering helps maintain signal integrity when routing is combined with downstream amplifiers, converters, or acquisition circuits. Because the verified material does not provide the complete electrical table, exact input impedance, output impedance, channel resistance, power consumption, temperature range, and detailed pin functions cannot be independently confirmed from the supplied sources.
Designers should place supply decoupling close to the analog IC and preserve the manufacturer’s recommended grounding and shielding topology around the input and output groups. The 14 mm × 14 mm LQFP package also requires adequate PCB escape routing and thermal consideration for high-frequency signal integrity. The verified distributor pages provide the product identity, package information, headline bandwidth, gain, supply arrangement, and switching behavior; final production design should therefore be validated against the complete Analog Devices datasheet, including absolute maximum ratings, recommended operating conditions, and the complete pinout.
This page consolidates the supplied manufacturer and distributor information, practical routing considerations, application guidance, and verified-source links. It distinguishes documented headline specifications from fields that still require confirmation from the full datasheet rather than inferring values that were not provided in the verified data.

主な用途
ADV3205JSTZ の用途: 6 件s: Professional Video Routing, Broadcast Video Signal Distribution, Video Test and Measurement, Camera and Monitor Signal Switching, Industrial Video Control Systems, Analog Signal Routing Backplane.
Professional Video Routing
The ADV3205JSTZ fits professional video-routing systems because its 16 × 16 matrix can connect numerous analog sources to selected processing or monitoring paths. The verified 60 MHz bandwidth supports the stated video application, while the +2 dB gain provides a defined signal transfer. Buffered paths help isolate source and destination loading compared with a passive matrix. Designers should use the manufacturer’s grounding and shielding layout around inputs and outputs, then verify cable and source-impedance compatibility. Switching below 60 ns with 0.1% settling also makes the device suitable for systems where a source selection must become usable quickly.
おすすめ
Broadcast Video Signal Distribution
The ADV3205JSTZ can distribute analog video sources within broadcast and production routing systems by placing its 16 × 16 matrix between source selection and downstream processing. Its 60 MHz bandwidth is the principal verified suitability parameter for these applications. The active buffered architecture is valuable when multiple switched outputs must retain controlled behavior, although channel isolation and output-impedance limits must be checked in the full datasheet. Ground and power pins surrounding the signal groups should be connected according to the manufacturer layout to minimize coupling between routes and preserve the intended shielding.
おすすめ
Video Test and Measurement
The ADV3205JSTZ is useful in test systems that must route one of several video sources to an instrument, display, or signal-analysis chain. Its less-than-60-ns channel switching and 0.1% settling behavior support rapid test-sequence changes, while the buffered matrix reduces the loading concerns associated with a passive network. The 60 MHz bandwidth permits routing of signals within the manufacturer’s stated video bandwidth. For measurement accuracy, engineers should characterize source impedance, termination, cable effects, and downstream bandwidth because the verified excerpts do not provide the complete noise or isolation specifications.
おすすめ
Camera and Monitor Signal Switching
The ADV3205JSTZ can support camera-to-monitor switching in monitoring and surveillance installations with multiple analog video sources. The 16 × 16 crosspoint provides a larger routing field than a single-channel selector, while 60 MHz bandwidth and +2 dB gain align with the device’s stated video role. Buffered channels are advantageous when several source cables and termination networks are connected. Because long cable runs can introduce reflections and attenuation, designers should verify source impedance and settle the PCB layout using the manufacturer’s reference guidance before deploying the part in critical monitoring paths.
おすすめ
Industrial Video Control Systems
The ADV3205JSTZ can route analog video signals in industrial inspection or control systems that require selection among multiple camera or observation sources. The matrix combines 16 inputs and 16 outputs in a single buffered device, and the verified 60 MHz bandwidth is suitable for the manufacturer’s intended video applications. Fast switching below 60 ns may help reduce the transition interval when a control system changes views. Industrial implementation should still verify operating-temperature limits, supply tolerances, isolation, and system grounding because those details were not included in the supplied verified excerpts.
おすすめ
Analog Signal Routing Backplane
The ADV3205JSTZ can serve as a buffered analog routing element in a larger backplane or multi-stage signal-routing architecture. Its fully buffered topology helps preserve controlled signal transfer across the 16 × 16 matrix, while the ±5 V supply arrangement supports conventional high-performance analog routing. The surrounding ground and power pins are intended to provide shielding between inputs and outputs, making careful layer assignment and decoupling essential. Designers should preserve short return paths, follow the reference pin layout, and verify high-frequency channel isolation and crosstalk against the complete datasheet before production.

選定ガイド
設計ノート
Preserve the manufacturer's recommended ground and power distribution around the input and output groups. The verified product summary specifically identifies surrounding ground and power pins as a shielding feature, so the PCB should avoid routing fast signal paths between those groups. Place input and output decoupling components close to their associated pins and use continuous ground references beneath the device where the datasheet layout permits.
Treat the 60 MHz bandwidth as the principal verified routing guideline and preserve controlled impedance from each source to the selected output. Terminate cables and source networks according to their own requirements rather than adding arbitrary capacitance at the IC. Validate the complete path because the supplied excerpts do not provide input impedance, output impedance, crosstalk, or output-voltage specifications, all of which affect 60 MHz behavior.
Place the ADV3205JSTZ so that high-speed analog routes are short, direct, and surrounded by a continuous ground plane. The 100-LQFP package requires adequate escape routing for 16 input and 16 output channels, and its 14 mm × 14 mm body provides limited routing space around all terminals. Review the complete Analog Devices pinout and recommended PCB artwork before assigning nets because the supplied data confirms the package but not the individual pin mapping.
Do not infer that any similarly described 16 × 16 crosspoint is a drop-in replacement. A valid replacement must match the 100-LQFP footprint, pin assignment, ±5 V supply arrangement, 60 MHz bandwidth, +2 dB gain, buffering behavior, and required isolation. The supplied cross-reference search did not identify a confirmed compatible alternative, so a candidate should be accepted only after comparison with the full ADV3205 datasheet.
コンプライアンス情報
The supplied verified excerpts do not provide explicit RoHS, REACH, lead-free, halogen-free, or conflict-minerals statements. AEC-Q100 status is marked not_applicable because no automotive qualification is identified in the supplied data.
