ADV7195KS - 3-Channel 11-Bit Video DAC Encoder | Analog Devices
Артикул: ADV7195KS ✗ Снят с производстваADV7195KS Обзор
A video DAC is an interface-integrated data converter that transforms digital YCrCb video samples into three analog color-component outputs. Within the broader signal-chain hierarchy, the ADV7195 belongs to the video encoder family, which combines digital-to-analog conversion with color encoding. This makes it suitable for professional video equipment, broadcast infrastructure, display-generation systems, and other multichannel analog-video applications where three coordinated outputs are required.
The verified part description identifies three high-speed video D/A converters with TTL-compatible inputs. It also identifies progressive-scan and HDTV encoder operation with a 10-bit data input. These features distinguish the ADV7195 from lower-resolution or single-channel DAC solutions. The manufacturer data supplied for this record does not include a complete electrical limit table, so individual voltage, timing, clock, output, and temperature values remain marked for data collection rather than being inferred.
The device uses YCrCb component coding, with the verified input options covering 4:2:2 and 4:4:4 arrangements. In practical systems, the input architecture must match the source format and resolution. The three-channel organization supports separate analog outputs for the luma-related and chroma-related video signals, while the exact sync and blanking implementation must be established from the manufacturer datasheet and application schematics before layout is released.
Typical uses include professional broadcast monitors, video test and measurement equipment, HDTV production infrastructure, progressive-scan display systems, and video signal-generation equipment. In each case, the ADV7195KS can combine a digital video source with three DAC channels while preserving the intended progressive-scan or HDTV signal architecture. System designers should still validate timing, DAC settling behavior, output compliance, and synchronization against their specific source and load requirements.
The most important design consideration is interface verification. Because the available verification identifies a 52-lead MQFP package but does not provide a complete authoritative pin table, the pinout should be checked directly against the Analog Devices datasheet before PCB routing. Input timing, DAC output reference, supply rails, decoupling, and unused-pin handling must also follow the datasheet rather than assumptions based only on generic video-encoder practice.
This page consolidates the verified ADV7195KS function, package information, lifecycle evidence, sourcing references, and cross-reference candidates into an engineering-focused product record. It also distinguishes confirmed drop-in alternatives from related encoder families that may require different packages or verification, helping procurement and design teams avoid treating functional similarity as guaranteed pin compatibility.

Типичное применение
ADV7195KS подходит для 6 применениеs: HDTV Video Encoding, Progressive-Scan Display Systems, Broadcast Video Infrastructure, Professional Video Test Equipment, Video Signal Conversion, Legacy Display and Monitor Repair.
HDTV Video Encoding
The ADV7195KS fits HDTV conversion paths because it combines three high-speed 11-bit DACs with a 10-bit digital interface for YCrCb 4:2:2 or 4:4:4 data. Position the device between a digital video processor and three analog video outputs, then validate source timing, synchronization, output loading, and DAC settling against the complete Analog Devices datasheet. The confirmed progressive-scan/HDTV positioning is preferable to selecting a generic multi-channel DAC whose interface and color-format support are unknown.
Рекомендуется
Progressive-Scan Display Systems
The ADV7195KS is applicable when a progressive-scan display system needs three coordinated analog color outputs from a 10-bit digital video source. Its verified 11-bit DAC architecture provides the output conversion path, while the TTL-compatible input interface supports integration with digital video logic. Engineers must still confirm pixel-clock range, blanking behavior, sync handling, output impedance, and connector requirements from the authoritative datasheet because these values are not present in the supplied verification.
Рекомендуется
Broadcast Video Infrastructure
The ADV7195KS can provide the final digital-to-analog video stage in broadcast monitoring or signal-conversion equipment requiring progressive-scan or HDTV operation. Its three 11-bit DAC channels map naturally to a YCrCb output structure, while the 10-bit input supports conventional 4:2:2 and 4:4:4 source formats. Because the target is obsolete, repair designs should prioritize an approved equivalent with a documented pin-level review, and new broadcast projects should evaluate lifecycle risk as well as nominal performance.
Рекомендуется
Professional Video Test Equipment
The ADV7195KS is well suited to video test and measurement equipment that converts a digital test pattern into three analog component outputs. The confirmed 10-bit YCrCb input and three 11-bit DAC channels support a self-contained test generator or converter architecture, while progressive-scan/HDTV support aligns with legacy professional television analysis systems. Before using it in new instrumentation, obtain the full timing and output specifications and verify that its obsolete status does not undermine calibration traceability or long-term maintenance planning.
Рекомендуется
Video Signal Conversion
The ADV7195KS can serve as the analog-output stage in equipment that receives 10-bit digital video and produces three YCrCb component signals. Its support for both 2 x 10-bit 4:2:2 and 3 x 10-bit 4:4:4 arrangements allows the surrounding controller to select the source organization matching the system architecture. Layout and signal-integrity work should minimize digital-clock crosstalk into the DAC outputs and preserve the manufacturer’s recommended component values and grounding topology.
Рекомендуется
Legacy Display and Monitor Repair
The ADV7195KS is relevant to repair of legacy professional monitors and video displays that specifically use its three-channel 11-bit DAC arrangement and 52-lead MQFP footprint. In a like-for-like repair, retaining the original device minimizes changes to clocking, supply distribution, analog output routing, and synchronization. If the original is unavailable, use a qualified replacement only after comparing every pin, both supply requirements, DAC output compliance, clock setup, and thermal limits against the board schematic.

Заметки по проектированию
Do not treat every name in a cross-reference table as a guaranteed drop-in replacement. The verified record names ADV7195KSZ, SAA7120H, SAA7129AHB, and SAA7128AH, but it does not provide complete pin tables or electrical limits. Before substituting any candidate, compare all 52 pins, supply rails, reference voltage, clock inputs, data mapping, sync, DAC outputs, and package drawings against the original ADV7195KS datasheet.
Separate the 10-bit digital video interface from the three analog DAC outputs as far as practical, and route high-speed clock edges away from sensitive output nodes. Use the manufacturer’s recommended decoupling and grounding arrangement because generic MQFP layouts cannot establish the correct return-current path. The supplied verification lacks the reference schematic and complete pinout, so these implementation details must come directly from the Analog Devices datasheet.
Estimate dissipation only after obtaining the actual supply voltage, operating current, DAC loading, and ambient temperature from the manufacturer datasheet. Estimated: Pdiss equals the sum of supply-input power and output-current power, adjusted according to the efficiency equation stated in that datasheet; junction rise then equals Pdiss multiplied by the applicable junction-to-ambient thermal resistance. Obsolete status does not relax absolute maximum ratings or permit unchecked substitutions.
