ADV7177KSZ - 3-Channel 9-Bit Video Encoder | Analog Devices
Артикул: ADV7177KSZ ✗ Снят с производстваADV7177KSZ Обзор
A video encoder is an interface IC that converts digital pixel data into legacy analog television signals. In the broader signal-chain hierarchy, it sits between a digital video processor and an external display or broadcast system. The ADV7177KSZ integrates three 9-bit video DACs with encoding circuitry, allowing three independently addressed video outputs to be served from one device.
The verified feature data identifies 9-bit DAC resolution with integral nonlinearity below 1 LSB, digital input, analog output, and operation from 3 V to 3.6 V. Its commercial temperature range is 0°C to +70°C. A single 27 MHz clock reference is listed in the available source material, providing the timing foundation for the digital input and encoded analog outputs. The 44-MQFP package supports compact surface-mount integration.
Technically, the device belongs to the video encoder and DAC conversion category rather than a general-purpose processor. Its YCrCb input simplifies connection to digital video pipelines using ITU-R BT.601/BT.656 formatting. Three integrated DAC channels reduce the need for separate output converters when a design requires several encoded video signals, although external synchronization, termination, and connector details must follow the complete manufacturer documentation.
Typical uses include set-top box video outputs, television and monitor interfaces, digital video processing equipment, and legacy PAL or NTSC test systems. The ADV7177KSZ is most appropriate when the system already produces compatible YCrCb digital video and still needs three analog outputs. It is less suitable for designs requiring modern digital display interfaces such as HDMI or DisplayPort.
Designers should verify clock timing, input mapping, DAC output levels, and package pin assignments in the manufacturer datasheet before layout release. Proper analog-output routing, ground-return management, and supply decoupling are important because encoded composite video quality can be affected by noise and return-path discontinuity.
This page consolidates verified distributor specifications, package details, sourcing information, and engineering-oriented application guidance. It distinguishes documented capabilities from missing data and avoids presenting unverified pricing, pin mappings, or lifecycle claims as established facts.

Типичное применение
ADV7177KSZ подходит для 6 применениеs: Set-Top Box Analog Video Output, Television Video Interface, Digital Video Processor Interface, PAL/NTSC Video Test Equipment, Digital-to-Analog Video Conversion, Legacy Video Conversion Module.
Set-Top Box Analog Video Output
The ADV7177KSZ fits a set-top box that receives ITU-R BT.601/BT.656 YCrCb data and must generate legacy television outputs. Its three integrated 9-bit DAC channels provide a practical way to produce multiple analog video signals from one encoder package. Verified support for NTSC-M and several PAL variants allows regional output configurations, while the 3 V to 3.6 V supply range simplifies integration with contemporary 3.3 V digital video logic. The trade-off is that the encoder supports analog television signals rather than HDMI or DisplayPort, so systems using the part must preserve a PAL or NTSC output stage.
Рекомендуется
Television Video Interface
The ADV7177KSZ is appropriate for television and monitor equipment that needs to convert a digital YCrCb video stream into analog PAL or NTSC signals. DigiKey identifies set-top boxes and TV as relevant equipment, while the verified feature data lists NTSC-M, PAL-M/N, and PAL-B/D/G/H/I support. Three 9-bit DAC channels can serve multi-output arrangements, but engineers must verify output levels, synchronization, and connector topology in the complete manufacturer documentation. The part is best suited to installed-base analog interfaces rather than next-generation digital display ports.
Рекомендуется
Digital Video Processor Interface
The ADV7177KSZ can serve as the final encoding stage of a digital video processor that already outputs ITU-R BT.601/BT.656 YCrCb data. Its digital input and analog output structure directly bridges the processor and legacy television circuitry, avoiding an intervening general-purpose conversion concept. The single 27 MHz reference identified in the verified feature data provides the device timing basis. Integration requires careful clock routing and verification of pixel timing, blanking, and synchronization because those implementation details are not fully available in the supplied excerpts.
Рекомендуется
PAL/NTSC Video Test Equipment
The ADV7177KSZ is useful in test equipment that must generate controlled PAL or NTSC analog video from digital YCrCb test patterns. The verified support list covers NTSC-M, PAL-M/N, and PAL-B/D/G/H/I, allowing one board design to address several television markets. Three integrated DACs may simplify multi-output test points, while the 9-bit resolution gives the documented conversion granularity. Calibration and output-amplitude verification remain essential because the supplied data does not specify output voltage, gain accuracy, or calibration procedures.
Рекомендуется
Digital-to-Analog Video Conversion
The ADV7177KSZ belongs at the boundary between digital video processing and analog display equipment because it converts ITU-R BT.601/BT.656 YCrCb input into analog PAL or NTSC outputs. Three integrated 9-bit DAC channels distinguish it from a simple one-channel converter and can reduce package count in multi-output designs. The 44-MQFP package is only 10 mm by 10 mm, but its fine-pitch routing demands careful PCB layout. Designers should provide a stable 27 MHz reference and validate grounding and return paths to preserve composite-video quality.
Рекомендуется
Legacy Video Conversion Module
The ADV7177KSZ can anchor a dedicated legacy-video conversion module that accepts digital YCrCb and exposes PAL or NTSC outputs for service equipment or installed television products. Its 3 V to 3.6 V operating supply and integrated three-channel DAC architecture keep the core converter compact, while the 44-MQFP package allows a surface-mount implementation. The module must still include the required clock, synchronization, output network, connectors, and bypass components. Because current pricing and lifecycle status are not numerically verified, long-running programs should secure supply and compliance evidence before layout freeze.

Заметки по проектированию
Treat the analog video outputs and the single 27 MHz reference as sensitive signal paths. Route clocks on short, continuous traces with a stable reference return, and keep switching-node and digital-clock routing away from composite-video nets. Grounding and output-network details must follow the complete ADV7177 datasheet, because pin assignments and component values were not included in the verified excerpts.
Operate the encoder only within the verified 3 V to 3.6 V supply range. Place local supply bypass components close to the device using the package pin assignments and network values specified by Analog Devices. Confirm voltage tolerance, sequencing, and exposed thermal requirements in the manufacturer documentation before layout release; the supplied data does not establish quiescent current or absolute maximum ratings.
Do not substitute the generic 44-MQFP package drawing for a verified pinout. The available web results confirm a 44-MQFP, 10 mm by 10 mm package but do not provide a reliable pin-number-to-function table. Verify digital data inputs, clock, power, synchronization, DAC outputs, and configuration pins directly from the manufacturer datasheet before schematic capture or PCB routing.
