ADV7173KSTZ - PAL/NTSC Video Encoder | Analog Devices
部品番号: ADV7173KSTZ ✓ 生産中ADV7173KSTZ 概要
A video encoder is an interface IC that bridges a digital video-processing system and an analog video connection. It accepts parallel digital component-video data, applies the required encoding and signal conversion, and produces composite video plus selectable S-VHS Y/C, RGB, or YUV outputs. The ADV7173 integrates six DACs so multiple analog outputs can be generated without separate external converter stages.
The device supports PAL and NTSC encoding, color-signal control, burst-signal control, and enhanced power management. Its six 10-bit DACs provide the analog output resolution stated for the ADV7172/ADV7173 family, while the digital input path is specified as CCIR-601 4:2:2 8-bit component data. These features make the encoder useful in video test equipment, broadcast processing equipment, industrial imaging systems, and legacy audiovisual installations where digital video must be converted to analog baseband signals.
The commercial ADV7173KSTZ ordering code uses a 48-lead LQFP package and is specified for a 0 °C to +70 °C operating range. The 7 mm × 7 mm surface-mount package provides 48 terminals in a gull-wing square format. A single 3 V to 3.6 V supply range supports integration with contemporary 3.3 V digital logic, although each board still requires suitable analog-output drive, bypassing, and signal-routing discipline.
When designing around the ADV7173KSTZ, verify the complete pin assignment and timing relationships in the manufacturer datasheet before routing the board. Keep analog outputs away from high-speed digital clocks, provide local supply decoupling at the device, and observe the video timing requirements for the selected PAL or NTSC mode. The encoder’s principal trade-off is that it adds six analog output channels and associated board area instead of using a purely digital video interface.
This page consolidates the confirmed encoder specifications, package information, functional use cases, practical design guidance, and verified drop-in alternatives for faster engineering selection and sourcing review.

主な用途
ADV7173KSTZ の用途: 6 件s: Broadcast Video Test Equipment, Professional Video Conversion, Industrial Imaging Systems, Digital-to-Analog Video Teaching Systems, Legacy Audiovisual Retrofit, Video Signal Conditioning and Distribution.
Broadcast Video Test Equipment
The ADV7173KSTZ fits broadcast test equipment that converts digital test patterns into PAL or NTSC analog baseband video. Its CCIR-601 4:2:2 8-bit input accepts component-video data, while six 10-bit DACs generate composite, S-VHS Y/C, RGB, or YUV outputs. This combination allows one instrument to exercise several analog video paths. The 3 V to 3.6 V operating range also aligns the encoder with a 3.3 V test-system architecture, although video timing, impedance, and output-level calibration remain essential for accurate measurements.
おすすめ
Professional Video Conversion
The ADV7173KSTZ supports professional video-conversion equipment requiring simultaneous analog outputs from a digital source. Six integrated 10-bit DACs simplify the output architecture, and the encoder can provide composite, Y/C, RGB, and YUV signals for monitors, capture systems, and downstream processing. Compared with a system using separate DACs, the integrated encoder reduces component count and board complexity. Its PAL/NTSC compatibility supports international television workflows, while the commercial 0 °C to +70 °C rating suits controlled indoor equipment environments.
おすすめ
Industrial Imaging Systems
The ADV7173KSTZ can bridge digital imaging data to legacy analog displays in industrial inspection, machine-vision, and laboratory systems. Digital component video enters through the CCIR-601 4:2:2 interface, and the encoder produces standard PAL or NTSC outputs for long-established monitors or recording equipment. Six 10-bit DACs provide multiple analog destinations without separate converter ICs. The principal constraint is the 0 °C to +70 °C commercial temperature range, so enclosure temperature control or a wider-temperature family variant is necessary for harsh installations.
おすすめ
Digital-to-Analog Video Teaching Systems
The ADV7173KSTZ works well in education and demonstration systems that teach how digital component-video data becomes analog PAL or NTSC television signals. Students can observe composite, Y/C, RGB, and YUV outputs from one encoder, with six 10-bit DACs exposing the conversion stages. The 48-LQFP package and 3 V to 3.6 V supply also allow the part to fit a modern 3.3 V digital teaching platform. Clear test points and controlled input timing help users connect digital pixel formats, synchronization, color encoding, and practical video termination.
おすすめ
Legacy Audiovisual Retrofit
The ADV7173KSTZ enables legacy audiovisual equipment to be retained while accepting a modern digital video source. It converts CCIR-601 4:2:2 8-bit video into PAL or NTSC baseband signals for older projectors, displays, and recording devices. Its composite, S-VHS Y/C, RGB, and YUV paths support several display connections, while integrated DACs simplify the converter. The design must accommodate the encoder’s commercial temperature range and provide appropriate impedance matching, grounding, and isolation to prevent noise or ground loops from degrading the analog picture.
おすすめ
Video Signal Conditioning and Distribution
The ADV7173KSTZ can serve as the analog-output stage in a video conditioning or distribution system that accepts digital component data and drives several standard video formats. The six 10-bit DACs allow composite and Y/C, RGB, or YUV outputs to be generated from the same encoder, which is useful for comparison monitoring and laboratory distribution. Because these are analog baseband outputs, correct source termination, impedance matching, and short routing paths are essential. The 3 V to 3.6 V supply supports integration into 3.3 V signal-processing equipment without a separate high-voltage output stage.

設計ノート
Use the manufacturer package drawing to define the 48-LQFP land pattern, including lead length, toe, and courtyard clearance. Place local supply-decoupling capacitors close to the device pins and provide a low-impedance ground connection. Keep analog video traces short and away from clocks, switching converters, and high-speed digital buses to minimize crosstalk and ground-current coupling into the output signals.
Treat the composite, Y/C, RGB, and YUV outputs as analog baseband signals even though their source is a digital encoder. Terminate each routed output according to the connected video equipment and interface standard, avoid unnecessary stubs, and maintain controlled impedance on long traces. Verify output amplitude, synchronization polarity, chroma behavior, and timing with representative PAL or NTSC equipment before production release.
Separate digital-video inputs from analog outputs when practical, while following the datasheet's recommended input and output layout. Provide a stable common reference between digital and analog sections and avoid routing video outputs beneath noisy regulators or switching nodes. Because the device includes six 10-bit DACs, unused outputs should still follow the manufacturer's termination and test-point guidance rather than being left as uncontrolled branches.
Do not substitute a family member solely because it uses a 48-LQFP package. Confirm the exact pin names, supported output modes, sync and blanking behavior, control registers, DAC availability, supply limits, and temperature grade in the candidate's datasheet. The ADV7173KSTZ is a commercial 0 °C to +70 °C part; use a wider-temperature variant for equipment operating outside that range.
