ADV7195KSZ - Triple 11-Bit HD Video Encoder | Analog Devices
부품 번호: ADV7195KSZ ✗ 단종ADV7195KSZ 개요
A video encoder is an interface IC that converts digitally represented video signals into analog component or RGB video suitable for conventional broadcast, studio, and professional video equipment. Within the broader signal-chain hierarchy, this device belongs to the video interface and encoder category, where digital pixel data is translated into legacy analog transmission formats.
The ADV7195KSZ provides three synchronized 11-bit DACs, supporting Y, Cr, and Cb signal generation from digital YCrCb input. Its 3.3 V operating supply includes a specified 3.15 V to 3.45 V analog-supply range, while the factory characteristics in the manufacturer datasheet are stated over 0°C to 70°C with a maximum junction temperature of 110°C. The documented reference voltage is 1.235 V, with a typical 2470 ohm RSET resistor and 300 ohm output loading condition.
The encoder supports EIA770.1, EIA770.2, and EIA770.3 component-video outputs as well as 4:4:4 RGB input. RS170 and RS343A-compatible RGB outputs broaden compatibility with professional and broadcast equipment. The manufacturer describes the device as a triple high-speed encoder for High Definition video, making digital source equipment, post-production systems, and legacy analog video bridges natural implementation areas.
Designers should pay close attention to DAC output loading, reference and RSET component accuracy, digital-interface timing, and analog-output routing. The 52-pin surface-mount package also requires adequate PCB land-pattern fidelity and grounding because simultaneous high-speed digital processing and three analog output channels can introduce coupling if layout guidance is not followed.
This page combines verified manufacturer information, distributor availability, pinout availability, application guidance, and strict drop-in replacement analysis to provide practical information beyond the basic datasheet specifications. Pricing reflects the verified distributor listing as of 2026-10-28, while lifecycle, pinout, and compliance details that were not explicitly verified remain clearly identified rather than inferred.

일반적인 애플리케이션
ADV7195KSZ 적합 용도: 6 애플리케이션s: Digital-to-Analog HD Video Bridges, Broadcast Studio Video Conversion, Professional Video Test Equipment, Post-Production Video Monitoring, RGB Video Interfaces, Legacy Video Equipment Interfaces.
Digital-to-Analog HD Video Bridges
The ADV7195KSZ fits digital-to-analog HD video bridges because it combines three 11-bit DAC channels with YCrCb input processing and EIA770.1, EIA770.2, and EIA770.3-compatible component outputs. A bridge can accept digital video from a graphics, broadcast, or production system and generate separate Y, Cr, and Cb analog signals for downstream monitors or legacy transmission equipment. The 3.15 V to 3.45 V supply range and 300 ohm output-load condition define key implementation constraints, while the 1.235 V reference and 2470 ohm RSET network establish the DAC operating condition. The 52-pin MQFP package keeps the converter compact while providing separate digital and analog signal connections.

Broadcast Studio Video Conversion
ADV7195KSZ is suitable for broadcast-studio conversion equipment that must translate digital High Definition sources into component video accepted by professional equipment. Its three 11-bit DAC channels support simultaneous Y, Cr, and Cb generation, while the documented EIA770 compatibility directly addresses component-video requirements. The device operates from a nominal 3.3 V supply, and the manufacturer specification uses a 1.235 V reference with 2470 ohm RSET resistance. In a studio path, preserving video timing and controlling analog output loading are essential, particularly when the encoder feeds long cables or several distribution stages downstream.
추천
Professional Video Test Equipment
The ADV7195KSZ can support professional video test equipment that must produce recognizable component or RGB outputs from controlled digital test patterns. Its three 11-bit DAC channels make it possible to reconstruct full YCrCb imagery, while 4:4:4 RGB input and RS170 or RS343A-compatible RGB outputs expand the range of supported generator signals. Engineers should use the documented 300 ohm output loading condition as a baseline and preserve the 3.3 V supply range throughout operation. Because the verified specification covers 0°C to 70°C with a 110°C maximum junction temperature, enclosure and airflow design must account for the local thermal environment.
추천
Post-Production Video Monitoring
ADV7195KSZ is applicable in post-production monitoring paths where a digital editing or review signal must drive analog component-video equipment. The encoder's YCrCb processing and three independent 11-bit DAC outputs provide a direct conversion route for Y, Cr, and Cb signals, while EIA770 compatibility helps align the output behavior with professional video expectations. Its 52-pin MQFP package supports compact implementation, but accurate reference and set-resistor components remain necessary for stable output amplitude. PCB layout should isolate digital timing paths from the three analog outputs to reduce the chance of visible artifacts or color errors during critical review.
추천
RGB Video Interfaces
The ADV7195KSZ supports equipment requiring an RGB 4:4:4 input and analog RGB outputs. According to the Analog Devices product page, RGB input is supported alongside YCrCb, and the resulting RGB outputs are compatible with RS170 and RS343A. This makes the device relevant to professional RGB monitoring and signal-conversion equipment where separate red, green, and blue analog channels are required. The three 11-bit DACs provide the required parallel conversion, but each output must be loaded and routed in accordance with the manufacturer's application guidance to preserve amplitude, bandwidth, and color fidelity.
추천
Legacy Video Equipment Interfaces
ADV7195KSZ provides a practical interface between modern digital video sources and legacy analog equipment. Its component outputs support EIA770.1, EIA770.2, and EIA770.3, while the RGB path supports RS170 and RS343A, allowing the same converter concept to serve several professional-video conventions. The nominal 3.3 V supply simplifies integration with contemporary digital logic, and the 52-pin MQFP format supports surface-mount assembly. The principal trade-off is that any replacement must preserve both the package footprint and the complete signal-pin arrangement, so engineers should verify the official pin table rather than rely on the shared encoder family name alone.

설계 노트
Implement the 52-pin MQFP land pattern directly from the official Analog Devices package drawing and keep analog outputs away from high-speed digital clock and data routing. Route Y, Cr, and Cb outputs as short, controlled-impedance paths where applicable, and place the associated output-network components close to their relevant pins. The verified web material does not provide a complete reference layout, so the manufacturer datasheet layout section and recommended component placement should take precedence over generic guidance.
Design the 3.3 V analog and digital supply system so it remains inside the manufacturer's 3.15 V to 3.45 V analog-supply range during startup, transient, and full-load conditions. Decouple the supply pins with the capacitance and placement specified by Analog Devices, and keep switching-regulator switching nodes and inductors away from the reference and analog-output paths. The verified 1.235 V reference and 2470 ohm RSET values must also be implemented using appropriately stable, accurate components.
Treat the digital input, DAC reference network, and three analog outputs as separate but coordinated domains. Use short, properly terminated digital routes and preserve the manufacturer's recommended clock and data-interface timing. Verify the analog outputs against the documented 300 ohm loading condition before adding cable, distribution, or repeated downstream stages. Because the supplied material does not expose the complete digital-interface timing table, engineers should use the official ADV7195 datasheet for edge timing, settling, and output-impedance requirements.
Use the manufacturer's 110°C maximum junction temperature and 0°C to 70°C specified operating range as thermal checkpoints rather than assuming unrestricted commercial-temperature operation. Monitor dissipation from the three DAC channels and any digital-interface loading under worst-case output conditions. Provide copper area around the 10 mm x 10 mm MQFP where the package drawing permits it, and account for enclosure temperature rise. Actual power and junction-temperature calculations require the selected operating mode and board thermal data and are therefore not estimated here.
규정 준수 정보
The supplied manufacturer and distributor snippets do not explicitly state RoHS, REACH, lead-free, halogen-free, or conflict-minerals status. ADV7195KSZ is an industrial video interface IC rather than an automotive-qualified device, so AEC-Q100 is marked not applicable.
