ADV7171KSU 10-Bit PAL/NTSC Video Encoder | Analog Devices
MPN： ADV7171KSU ✓ 啟用中ADV7171KSU 概覽
A video encoder is a signal-conversion semiconductor that accepts digital pixel data and generates an analog waveform accepted by PAL or NTSC display equipment. Within the product hierarchy, the ADV7171 is an interface IC and video encoder rather than a processor or display driver. The corresponding digital-video-to-analog-video conversion stage sits between a video source, such as a DVD controller or multimedia processor, and an analog video connector or display.
According to the Analog Devices ADV7171 product page, the encoder supports 8-bit or 16-bit CCIR-601 4:2:2 component video input. Its four 10-bit DACs support PAL and NTSC generation, while its digital video input follows the BT.601/656 format identified in the provided product information. This integration reduces the need for external video DACs when a design requires both S-Video and composite or additional analog video outputs.
The ADV7170 and ADV7171 family is positioned for high-performance DVD playback, portable video equipment, digital still cameras, laptop computers, video games, and PC video or multimedia systems. The supplied search data does not provide verified clock frequency, power-supply range, output voltage resolution, operating temperature, timing limits, or package dimensions beyond the 10 mm by 10 mm TQFP description, so those values are not inferred here.
The main engineering concern is interface compatibility rather than power conversion. The source must supply correctly timed BT.601/656 YCrCb data, the PCB must route high-speed digital video signals without excessive distortion, and analog outputs must be terminated according to the selected PAL or NTSC standard. The exact clocking, synchronization, control-register, and DAC configuration procedure must be taken from the manufacturer data sheet rather than inferred from the order code.
For procurement, ADV7171KSUZ and ADV7171KSUZ-REEL appear in the supplied cross-reference results as the same 44-pin device with compatible terminals and characteristics, but the KSUZ order codes may represent ordering or reel-packaging conventions rather than five distinct functional alternatives. This page therefore distinguishes verified function-level choices from packaging suffixes and does not present reel-code variants as separate engineering options.
This page consolidates the supplied manufacturer description, distributor package information, cross-reference findings, application guidance, and unresolved-data warnings. It is intended to support engineering selection and sourcing while directing readers to the manufacturer data sheet for authoritative electrical limits, pin functions, register definitions, and timing specifications.

典型應用
ADV7171KSU 適用於 6 應用s: DVD Player Analog Video Output, Laptop PC Video and Multimedia, Portable Video Equipment, Digital Still Camera Video Interface, Video Game Console Output, Set-Top Box Analog Television Output.
DVD Player Analog Video Output
The ADV7171KSU fits a DVD player that accepts digital component video but must drive PAL or NTSC displays through analog connectors. Its four integrated 10-bit DACs provide the conversion stage from CCIR-601 4:2:2 YCrCb data to analog baseband video, reducing reliance on discrete output converters. The source controller must provide correctly timed digital video and configure the encoder for the intended television standard. The supplied data identifies high-performance DVD playback as a family application but does not provide output-filter values, so those must be derived from the manufacturer interface documentation and target impedance rather than estimated here.
推薦
Laptop PC Video and Multimedia
The ADV7171KSU is suitable for legacy analog video support in laptop and PC multimedia designs that already produce CCIR-601 component data. It converts digital YCrCb video into PAL or NTSC analog baseband signals, allowing a system to retain VGA, composite, S-Video, or related analog display connections. The explicit inclusion of laptop PCs among the family's applications supports this use case. Actual deployment depends on source timing, connector requirements, platform availability, and analog output filtering; those implementation details are not included in the retrieved snippets and must be checked against the manufacturer data sheet.
推薦
Portable Video Equipment
The ADV7171KSU can serve portable video equipment that needs a compact digital-to-analog video bridge. Its 44-pin 10 mm by 10 mm TQFP package integrates four 10-bit video DACs beside the digital input interface, making it applicable where composite or S-Video compatibility must be retained. Portable video equipment is explicitly listed in the Analog Devices family application set. The supplied evidence does not include power consumption, operating temperature, or shutdown characteristics, so battery-life and thermal suitability cannot be concluded from this page and must be checked against verified electrical specifications.
推薦
Digital Still Camera Video Interface
The ADV7171KSU is applicable to digital still camera designs that process video digitally and require PAL or NTSC output for playback or external displays. The encoder accepts 8-bit or 16-bit CCIR-601 4:2:2 component data and uses four 10-bit DACs to generate the analog waveform. This family application is explicitly identified by Analog Devices. Integration reduces the number of separate video DAC channels, but the source ISP or processor must supply compatible YCrCb data and timing. The retrieved sources do not verify the required pixel clock, sync polarity, or output settling limits.
推薦
Video Game Console Output
The ADV7171KSU can provide legacy television output for a game console or graphics subsystem that receives digital YCrCb component video. Its integrated four-channel, 10-bit DAC architecture is designed to produce PAL or NTSC analog baseband video, which can support composite, S-Video, or other configured analog outputs. Video games are an explicitly stated application for the ADV7170 and ADV7171 family. Suitability for a particular console depends on whether its video engine already produces the required CCIR-601 data and whether latency, synchronization, and output filtering satisfy the target display system.
推薦
Set-Top Box Analog Television Output
The ADV7171KSU fits set-top-box designs requiring PAL or NTSC generation from digital CCIR-601 component video. Four integrated 10-bit DACs allow the encoder to serve multiple analog outputs while keeping the digital video source interface compact. The supplied DigiKey result categorizes the related ADV7171KSUZ as a video encoder for set-top boxes and video players, supporting the use case. A practical design must confirm input clocking, synchronization, register configuration, output filtering, and connector routing from the manufacturer documentation before schematic release.

主要差異化特點
- Four integrated 10-bit DAC channels (對比ADV7170KSU)
- Directly supported package-compatible sourcing path (對比ADV7171KSUZ)
- Explicit reel-format procurement option (對比ADV7171KSUZ-REEL)
- Broad legacy-video application positioning (對比ADV7171KSZ)
設計說明
Route the CCIR-601 digital video bus with short, continuous traces and controlled branch lengths so the encoder receives stable data and clock edges. The retrieved sources do not specify the permitted clock rate, trace impedance, or timing margin, so those values must come from the manufacturer interface specification. Avoid routing the digital bus beside analog video outputs where switching edge coupling could appear on the composite or S-Video waveform.
Separate the digital video input, control interface, power distribution, and analog output paths to minimize coupling into the four 10-bit DAC channels. Place required bypass and output-network components at the pins designated by the manufacturer reference design; values cannot be derived from the supplied snippets. Treat the TQFP power and ground planes as part of the high-speed digital return path rather than relying only on package traces.
Do not substitute an order-code suffix based only on appearance. The supplied cross-reference identifies ADV7171KSUZ and related reel variants as compatible, but it does not expose the complete ordering table for temperature grade, packing, or lifecycle. Before replacement, compare the full ordering suffix, package drawing, pin names, exposed-pad requirements, and control-register compatibility. In particular, verify that the alternate supplies the expected PAL or NTSC output configuration.
The retrieved data does not provide supply voltage, quiescent current, or active power consumption, so regulator sizing cannot be completed safely. Use the Analog Devices ADV7171 data sheet and the DAC operating mode of the final design to determine supply range and decoupling. The $3.5030 LCSC figure is a component price reference as of 2026-10-23, not an indication of supply voltage or power requirements.
