ADV7176AKS - 10-Bit 4-DAC PAL/NTSC Video Encoder | Analog Devices
料号： ADV7176AKS ✗ 停产ADV7176AKS 概述
A video encoder is an interface and signal-conversion device that translates digital component-video data into a legacy analog baseband format accepted by PAL and NTSC equipment. Within the broader product hierarchy, the ADV7176AKS is a video encoder IC, a signal-conversion integrated circuit, and ultimately a semiconductor used within professional video and broadcast equipment. Its CCIR-601 input interface and four analog output DACs consolidate digital-to-analog video conversion into one device.
The principal verified feature set includes 10-bit conversion, four DAC outputs, CCIR-601 4:2:2 input, and support for PAL B/D/G/H/I, PAL M, PAL N, and NTSC. Teletext insertion is identified in the verified product listing for the ADV7176AKS. These features make the device relevant where component-video data must be converted into standard analog television signals without relying on a collection of discrete output converters.
The 44-pin MQFP package provides 44 electrical connections for digital-video input, clock and control signaling, analog output channels, power, ground, and configuration functions. Exact pin names, voltage ratings, clock requirements, DAC output ranges, and absolute maximum ratings are not included in the supplied source excerpts; engineers should therefore use the Analog Devices ADV7176/ADV7176A manufacturer datasheet for implementation details rather than infer missing values from the family description.
Typical uses include PAL/NTSC video recording equipment, professional broadcast and post-production systems, digital-video test equipment, video standards-conversion products, and embedded television interfaces. The part accepts digital data upstream and produces analog baseband outputs downstream, making it suitable for equipment that must bridge modern digital processing with installed analog video infrastructure.
The most important design consideration is that this is an obsolete product, so new production designs should account for lifecycle risk, limited supply, and obsolete-product support constraints. Hardware redesign should begin by checking the complete pinout, electrical limits, synchronization requirements, DAC loading, and reference circuitry in the manufacturer datasheet. PCB layout should preserve short analog output paths and controlled digital-clock routing to reduce conversion-quality and timing risks.
This page consolidates verified lifecycle information, package details, functional characteristics, source links, and replacement-analysis constraints. It also distinguishes documented functions from unavailable electrical parameters and does not present unverified substitute parts as guaranteed drop-in replacements.

典型应用
ADV7176AKS 适用于 6 应用s: Professional Broadcast Video Encoding, PAL and NTSC Standards Conversion, Analog Video Recording Equipment, Digital Video Test Equipment, Video Acquisition and Processing Systems, Legacy Television Interface Equipment.
Professional Broadcast Video Encoding
The ADV7176AKS fits broadcast equipment that receives digital CCIR-601 4:2:2 component data and must generate standard analog baseband video. Its 10-bit conversion resolution and four integrated DACs provide the documented conversion core for PAL and NTSC outputs, including PAL B/D/G/H/I, PAL M, and PAL N. The device can sit downstream of a digital video processor and upstream of analog monitoring or recording equipment. The principal qualification is its obsolete lifecycle, so new broadcast platforms should compare supported alternatives unless an existing 44-pin MQFP design must be maintained.
推荐
PAL and NTSC Standards Conversion
ADV7176AKS is appropriate for standards-conversion products that translate processed digital component-video signals into legacy analog television formats. The verified 8-bit or 16-bit CCIR-601 4:2:2 input interface accepts digital video data, while four 10-bit DACs support analog output generation. Its multi-standard PAL and NTSC capability reduces the need for separate output paths when serving international markets. Engineers must verify synchronization, master-clock, DAC loading, and output-filter requirements in the manufacturer datasheet and should account for obsolete-product availability constraints.
推荐
Analog Video Recording Equipment
The ADV7176AKS can bridge a digital video pipeline to an analog recording system by accepting CCIR-601 4:2:2 data and producing PAL or NTSC baseband signals. The four-DAC architecture supplies the required digital-to-analog conversion stages within one 44-pin MQFP device, while 10-bit resolution supports the encoder's documented high-quality conversion role. In a recorder, the device would sit between the image-processing path and the analog input stage. Board-level grounding, clock routing, output termination, and filtering remain important for preserving signal quality.
推荐
Digital Video Test Equipment
ADV7176AKS is suitable for test and measurement products that need to generate controlled PAL or NTSC analog baseband video from digital CCIR-601 source data. Its documented 8-bit or 16-bit 4:2:2 input and four 10-bit DACs support repeatable stimulus generation for analyzing downstream analog-video circuitry. The 44-pin MQFP package is manageable for a dedicated instrument design, although clock distribution and synchronization must follow the manufacturer guidance. Since the part is obsolete, test-equipment builders should assess lifecycle risk and whether a supported encoder provides sufficient functionality for new platforms.
推荐
Video Acquisition and Processing Systems
ADV7176AKS can be placed at an analog-video boundary in acquisition systems that first process component video digitally and later require PAL or NTSC output. The CCIR-601 4:2:2 interface supports integration with digital video pipelines, and the four integrated DACs consolidate the documented output-conversion function. This arrangement is useful when overlays, scaling, or other processing occurs upstream. Careful synchronization and routing remain necessary because the encoder must preserve a coherent relationship among digital video data, clocks, synchronization signals, and the four analog outputs.
推荐
Legacy Television Interface Equipment
ADV7176AKS is applicable to legacy television-interface products that retain analog baseband outputs but use a digital video backbone. Its 10-bit DAC architecture and support for NTSC plus multiple PAL variants allow one design to target different television markets. The device is especially relevant when maintaining an existing 44-pin MQFP board because its documented package and encoder function are established. However, obsolete lifecycle status makes long-term availability uncertain, so engineers should secure traceable inventory or migrate to a currently supported encoder rather than assume continuing production.

设计说明
Do not treat an obsolete designation as proof that a different suffix is a drop-in replacement. The supplied excerpts confirm the ADV7176A/ADV7175A family architecture, 10-bit conversion, and four DACs, but they do not provide a complete ordering-code comparison. Before substitution, compare every pin on the 44-pin MQFP, supply rails, master-clock requirements, synchronization inputs, control interface, DAC output specifications, reset behavior, and absolute maximum ratings against the manufacturer datasheet.
Preserve the analog output topology and clock integrity defined by the manufacturer application information. Keep the four analog baseband output paths short, maintain controlled return paths, and prevent switching-node and digital-clock routing from coupling directly into DAC outputs. Input synchronization and master-clock lines should be routed with stable reference planes and appropriate termination. The supplied data does not specify trace lengths, impedances, or component values, so these must be derived from the complete manufacturer design guidance rather than guessed.
Plan the obsolete-product supply chain before committing a production release. Secure traceable inventory, record manufacturer and lot information, and obtain written confirmation of storage history and reconditioning status where applicable. The source excerpts do not provide operating voltages, absolute maximum ratings, current consumption, or power dissipation. Those values must be extracted from the 52-page manufacturer datasheet, then checked against the chosen supplier's condition and documentation.
合规信息
The supplied excerpts identify the part as a commercial-grade, obsolete video encoder but do not state RoHS, REACH, lead-free, halogen-free, or conflict-minerals status. These fields remain unknown rather than being inferred from the manufacturer or package.
