ADV7280BCPZ - 10-Bit Video Decoder | Analog Devices
MPN： ADV7280BCPZ ✗ 停產ADV7280BCPZ 概覽
A video decoder converts analog baseband imagery into a digital stream that a processor, image pipeline, display controller, or video recorder can consume. Within the semiconductor hierarchy, the ADV7280BCPZ is a video decoder and video interface IC rather than a general-purpose processor. It supports worldwide analog video standards, including composite and S-Video sources, while producing digital data that conforms to the ITU-R BT.656 specification.
Key capabilities include automatic multiformat detection, 10-bit digitization, four-times oversampling, and integrated deinterlacing. The digital interface includes pixel data, a line-locked clock, horizontal synchronization, and vertical synchronization or field indication. These functions support conversion of legacy analog video into a parallel digital format suitable for industrial imaging, broadcast equipment, security systems, video capture, and professional A/V installations.
The ADV7280 family is designed for multiformat analog baseband decoding. Its oversampled conversion architecture helps reconstruct a stable digital representation before the deinterlacer generates progressive-frame output. The manufacturer documentation identifies ITU-R BT.656 as the output format and describes separate synchronization outputs for integrating the decoder with downstream digital video logic.
Typical uses include CCTV camera capture, surveillance recording, industrial inspection, broadcast monitoring, video test equipment, and embedded analog-video conversion. System designers should budget for analog input filtering, stable clocking, correct synchronization routing, suitable output impedance, and power-supply decoupling. Review the pin-description and reference-circuit tables in the manufacturer datasheet before assigning tracks or laying out the analog input section.
This page combines manufacturer device information, verified lifecycle guidance, packaging details, drop-in replacement analysis, application guidance, and design considerations to support faster component evaluation and board-level implementation.

典型應用
ADV7280BCPZ 適用於 6 應用s: CCTV Surveillance Video Capture, Industrial Machine-Vision Interface, Broadcast Video Monitoring, Video Test and Measurement Equipment, Security Camera Analog-to-Digital Conversion, Legacy A/V Conversion and Display.
CCTV Surveillance Video Capture
The ADV7280BCPZ fits legacy CCTV installations that deliver NTSC or PAL composite video and require a digital capture path. Its automatic standard detection removes the need for manually configuring every camera format, while the 10-bit converter and four-times oversampling produce digital video for an image processor or recorder. The integrated deinterlacer simplifies progressive-frame handling downstream. Designers should use the ITU-R BT.656 pixel, line-locked clock, horizontal-sync, and vertical-sync outputs together, and should isolate the analog input routing from switching regulators and digital clocks.
推薦
Industrial Machine-Vision Interface
The ADV7280BCPZ is useful when an industrial camera or legacy inspection system exposes analog composite or S-Video rather than a modern digital camera interface. The decoder converts the source with 10-bit resolution, oversamples it four times, and applies integrated deinterlacing before presenting ITU-R BT.656 data to a processor. This consolidation can reduce the number of separate conversion and deinterlacing stages. For production equipment, layout must minimize analog trace impedance, maintain stable synchronization, provide local supply decoupling, and verify the complete camera-to-processor timing chain under temperature and power variation.
推薦
Broadcast Video Monitoring
The ADV7280BCPZ supports broadcast and professional monitoring equipment that must accept analog NTSC, PAL, or SECAM feeds and pass them into digital processing. Automatic input detection shortens configuration time, while the 10-bit, four-times-oversampled conversion stage provides a common digital source for scaling, measurement, recording, or display. The integrated deinterlacer helps present usable progressive imagery from interlaced analog sources. Signal integrity remains critical: keep analog inputs short, route returns continuously, use controlled reference impedances, and validate the line-locked clock and synchronization outputs with the downstream timing controller.
推薦
Video Test and Measurement Equipment
The ADV7280BCPZ can serve as the front end of a video test set that accepts several legacy analog standards. Automatic NTSC, PAL, and SECAM detection allows a single input stage to cover multiple source formats, while the digital output can be measured or compared against known video patterns. Its 10-bit conversion and integrated deinterlacing are useful when developing processing pipelines, synchronization interfaces, or digital capture adapters. The design must account for analog gain and offset, correct synchronization polarity, stable clocks, and output timing margins so measurement results are not dominated by board-level implementation errors.
推薦
Security Camera Analog-to-Digital Conversion
The ADV7280BCPZ is appropriate for security-camera adapters and recording systems that must digitize analog composite or S-Video camera output. Its automatic format detection supports mixed or changing camera sources, while the 10-bit conversion and integrated deinterlacer reduce the processing burden before digital compression or storage. The compact 5 mm by 5 mm 32-LFCSP package also supports space-constrained camera electronics. Robust implementation requires clean analog grounding, protected connector and cable pathways, local decoupling, and verification that the downstream processor correctly interprets BT.656 timing and the field or frame information.
推薦
Legacy A/V Conversion and Display
The ADV7280BCPZ bridges legacy analog video sources and modern digital display or processing pipelines. Composite and S-Video sources can be detected automatically and converted into an ITU-R BT.656 stream, allowing a digital controller to scale, crop, encode, or display the image. The integrated deinterlacer reduces the amount of processing required when working with interlaced material. Designers should evaluate chroma and luminance routing against the manufacturer reference circuit, maintain a continuous ground plane, and include timing checks for the line-locked clock, horizontal synchronization, and vertical synchronization or field signal.

主要差異化特點
- Manufacturer-confirmed software and pin compatibility (對比ADV7280A)
- Compact 5 mm by 5 mm video-decoder integration (對比ADV7280BCPZ-M)
- Single-chip analog-to-digital video path (對比ADV7280BCPZ-M)
設計說明
Treat the analog input path as a controlled-impedance, high-continuity signal path. Route composite or S-Video conductors away from switching nodes, clock outputs, and digital return currents; keep the analog ground reference continuous; and place the associated filtering and decoupling components at the device pins where the reference circuit permits. Validate the layout with eye, synchronization, and noise measurements because a correct decoder cannot compensate for unstable analog grounding or excessive connector-to-decoder trace length.
Do not substitute ADV7280A without checking both the IDENT value and the crystal-support network. Analog Devices documents the same pinout and software compatibility, but the replacement uses an updated IDENT code and a modified crystal circuit requiring an additional resistor. Update the device-detection logic and review the oscillator network before releasing revised production files; pin compatibility alone does not eliminate these two design changes.
Confirm the relationship among the BT.656 pixel output, line-locked clock, horizontal synchronization, and vertical synchronization or field indication. These signals form one timing system, so a partially rerouted or incorrectly terminated interface can create pixel displacement, field-identification errors, or unstable frame boundaries. Follow the manufacturer output recommendations, provide a continuous return path, and verify timing at the downstream receiver rather than relying only on endpoint measurements.
Place supply-decoupling components close to the device and follow the manufacturer reference schematic for capacitance, voltage rating, and topology. Separate sensitive analog routing from noisy digital activity, and provide an uninterrupted ground reference beneath the package and analog section. Check power-up behavior because the decoder, clock source, and downstream receiver must enter a valid synchronization state together.
