ADV7194KSTZ - 10-Bit Video Encoder | Analog Devices
Артикул: ADV7194KSTZ ✗ Снят с производстваADV7194KSTZ Обзор
A digital video encoder is an interface IC within the broader semiconductor hierarchy of video encoder, video interface, interface IC, and signal-processing semiconductor. Its role is to translate digital component-video data into the analog composite-video formats expected by conventional television equipment, set-top boxes, video processors, and other multimedia systems.
The ADV7194KSTZ supports standard NTSC output as well as PAL B, D, G, H, I, N, and PAL-60 formats. According to the Analog Devices ADV7194 product page, its integrated architecture accepts CCIR-601 4:2:2 component data and produces a standard analog baseband television signal. This combination of multi-format compatibility and integrated six-channel 10-bit DAC output reduces the external signal-chain complexity of a digital-video-to-analog-video design.
Professional extended-10 encoding with 54 MHz oversampling is the core performance feature identified for this device. Extended-10 operation provides additional processing headroom beyond a conventional eight-bit encoding path, while the six DAC channels correspond to the analog outputs required for composite video generation. The manufacturer describes the component as a video encoder IC for DVD, personal-computer video, and multimedia equipment.
Typical applications include professional broadcast video conversion, DVD player output stages, personal-computer video equipment, set-top box video paths, video test and measurement systems, and legacy analog displays that accept composite baseband video. In these systems, the encoder can sit between a digital video processor and an analog television or video-processing input while handling format conversion within a single integrated package.
The principal design consideration is interface verification. The CCIR-601 input width, synchronization requirements, pixel clock, supported output standard, DAC output topology, and power rails must be checked against the surrounding video pipeline before layout begins. The 80-lead LQFP also requires careful high-speed signal routing, solid ground-plane continuity, and decoupling close to the supply pins.
This page consolidates the manufacturer product information, exact package details, cross-reference candidates, interface requirements, and practical PCB considerations for engineers evaluating ADV7194KSTZ implementations. It emphasizes what must be confirmed in the datasheet rather than treating unrelated encoder functions as automatically interchangeable.

Типичное применение
ADV7194KSTZ подходит для 6 применениеs: DVD Player Video Output, Professional Broadcast Video Conversion, Personal-Computer Video Output, Set-Top Box Multimedia Output, Video Test and Measurement, Legacy Analog Display Interface.
DVD Player Video Output
The ADV7194KSTZ fits a DVD player architecture where decoded CCIR-601 4:2:2 component data must become an analog television signal. Its support for 8-, 10-, 16-, and 20-bit input allows the digital-video source to be matched to the selected interface depth, while six 10-bit DAC channels provide the integrated conversion resources associated with composite video generation. NTSC, PAL B/D/G/H/I, PAL N, and PAL-60 support allows regional output configurations to be accommodated. The implementation must synchronize the encoder correctly to the source pixel clock and verify output timing for the selected television standard.
Рекомендуется
Professional Broadcast Video Conversion
The ADV7194KSTZ is appropriate for broadcast equipment that receives digital CCIR-601 component video and must generate standard analog baseband output. Professional extended-10 encoding and 54 MHz oversampling provide the key processing characteristics for this conversion path, while the multi-standard support covers NTSC and several PAL variants. The encoder can serve as the final digital-to-analog stage before a conventional video monitor or downstream broadcast processor. Because this is an 80-lead LQFP device, the layout should minimize trace length around digital inputs and provide continuous ground-plane return paths beneath the high-speed interface.
Рекомендуется
Personal-Computer Video Output
The ADV7194KSTZ supports personal-computer video systems requiring conversion of digital component data into a television-compatible analog signal. A PC graphics or video subsystem can present CCIR-601 4:2:2 data at a supported 8-, 10-, 16-, or 20-bit width, after which the integrated encoder generates an NTSC or PAL baseband output. The six-channel, 10-bit DAC arrangement and 54 MHz oversampling distinguish this device from a simple low-resolution video DAC. Firmware must select the correct television standard and ensure that timing, blanking, and synchronization agree with the source stream.
Рекомендуется
Set-Top Box Multimedia Output
The ADV7194KSTZ can serve as the analog-video conversion stage in a set-top box or multimedia appliance that processes digital component video internally. The device accepts common CCIR-601 4:2:2 data widths and produces NTSC or multiple PAL-family outputs, making it suitable for systems designed for multiple television regions. Integrating the encoding and six 10-bit DAC functions reduces the need for separate conversion stages. The design should account for the encoder's separate supply domains, decouple each rail directly at its pins, and route the digital bus away from sensitive analog output paths to reduce potential coupling.
Рекомендуется
Video Test and Measurement
The ADV7194KSTZ is useful in video test equipment that needs to reproduce analog NTSC or PAL baseband signals from a controlled digital CCIR-601 source. Its four supported input widths, professional extended-10 processing, 54 MHz oversampling, and six 10-bit DAC channels permit multiple digital test patterns to be evaluated through an analog output stage. The encoder can simplify instrumentation intended to exercise legacy displays, processors, or transmission equipment. Calibration and test procedures should account for the selected output standard, synchronization timing, and the exact DAC output configuration defined in the datasheet.
Рекомендуется
Legacy Analog Display Interface
The ADV7194KSTZ allows a modern digital video source to interface with a display that accepts only analog composite baseband input. The source processor can supply CCIR-601 4:2:2 data in 8-, 10-, 16-, or 20-bit form, and the encoder converts it to NTSC or PAL output as required by the display installation. This is particularly useful in specialized multimedia equipment, conversion products, and professional installations with mixed-generation video paths. The output standard, pixel clock, synchronization signals, and connector-level signal integrity must be validated before the design is released for production.

Заметки по проектированию
Route the CCIR-601 digital input as a compact, controlled-length bus over a continuous ground plane. Keep the high-speed digital traces away from the analog DAC outputs, particularly around the 54 MHz processing domain. Use the manufacturer's recommended layer stack and termination topology, and match output-impedance requirements between the source processor and encoder.
The identified low-voltage supply range is 3.15 V to 3.6 V, while a second supply range appears in the product listing but is not fully stated. Place the required decoupling capacitance at each supply pin, maintain a low-impedance power and ground connection, and separate noisy digital return currents from analog output reference paths. Verify every supply, sequencing, and load requirement against the manufacturer datasheet.
Confirm pixel-clock rate, synchronization polarity, blanking intervals, and input data timing before enabling the encoder. The supported 8-, 10-, 16-, and 20-bit CCIR-601 widths can create different routing and timing conditions, and the selected NTSC or PAL mode must agree with the source timing. Validate the design with representative video patterns to detect setup, synchronization, and channel-mapping errors.
Do not treat an 80-LQFP footprint match as proof that two encoder ICs are functionally interchangeable. CS4954-CQZ, CS4955-CQZ, CS4955-CQZR, and ADV7188BSTZ must be checked for pin function, power rails, clock requirements, video formats, DAC configuration, and control-register compatibility. Preserve the original footprint only after a complete electrical and timing review.
