ADV7173KST - 10-Bit Six-DAC Video Encoder | Analog Devices
料号： ADV7173KST ✓ 量产中ADV7173KST 概述
A digital video encoder is an interface and signal-conversion integrated circuit. It belongs to the video codec, video interface, interface IC, and broader semiconductor hierarchy. The encoder accepts already digitized component video, generates the required analog color and luminance outputs, and provides the bridge between a digital video-processing pipeline and a conventional PAL or NTSC display or video system.
The ADV7173 provides six 10-bit DACs within one integrated encoder. The six-output arrangement supports generation of the component signals required for PAL or NTSC baseband video. Color-control functions allow the encoder to participate in calibrated video paths, while enhanced power management provides device-level control suited to systems where analog video circuitry must coexist with digital processing.
The ADV7173 operates with an 8-bit CCIR-601 4:2:2 component-video interface. This representation separates luminance and chrominance information and reduces chrominance resolution relative to the full raster. The encoder converts that digital representation into standard analog baseband television signals, with the resulting format selected for the target television system.
Typical uses include PAL and NTSC video encoding, digital video processing equipment, broadcast and professional video interfaces, video test systems, and embedded analog-video output stages. The encoder is especially relevant when a system must retain a conventional analog television output while accepting digital component video from an image processor, frame grabber, scaler, or video controller.
Designers should treat the complete ADV7173 data sheet as the controlling reference for supply voltages, timing, DAC configuration, sync generation, control registers, and application schematics. Because the supplied search excerpts identify the 48-lead LQFP package but do not expose the complete numbered pinout, the pin assignment must be verified in the manufacturer data sheet before PCB routing or replacement qualification.
This page consolidates the verified manufacturer description, marketplace price observations, package information, comparison targets, and practical qualification considerations. It distinguishes confirmed characteristics from unavailable specifications so engineers can make an evidence-based sourcing or drop-in replacement decision without relying on an inferred pinout.

典型应用
ADV7173KST 适用于 6 应用s: PAL and NTSC Video Encoding, Digital Video Processing Output, Broadcast Video Equipment, Video Test and Measurement, Industrial Video Inspection Systems, Legacy Video Retrofit.
PAL and NTSC Video Encoding
The ADV7173KST is specifically designed to convert CCIR-601 4:2:2 8-bit component video into standard analog baseband television signals for PAL or NTSC systems. Its six integrated 10-bit DACs provide the analog output conversion required by a conventional video output stage. The part is suitable when a digital image processor, scaler, capture engine, or graphics controller must drive an analog television or video monitor while retaining selectable PAL/NTSC compatibility.
推荐
Digital Video Processing Output
The ADV7173KST can form the analog-output boundary of a digital video-processing chain by accepting CCIR-601 4:2:2 8-bit component data and converting it into PAL or NTSC baseband video. Six 10-bit DACs consolidate multiple analog video conversions into one encoder package. This arrangement is useful in equipment that must expose legacy television outputs while the upstream signal remains digital, although synchronization, blanking, and standard selection must follow the manufacturer timing configuration.
推荐
Broadcast Video Equipment
The ADV7173KST is applicable to professional and broadcast-oriented equipment requiring a controlled transition from digital component video to standard PAL or NTSC baseband output. Its CCIR-601 4:2:2 8-bit input and six 10-bit DACs support an integrated encoder architecture, reducing the number of separate converter devices required near the analog output section. Actual broadcast compliance still depends on the complete signal timing, external synchronization arrangement, board layout, and the specific television standard selected.
推荐
Video Test and Measurement
The ADV7173KST can be used in video test equipment, signal generators, and service instruments that need to produce conventional PAL or NTSC analog video from digital component data. Its integrated six-DAC arrangement allows the test system to create multiple analog video outputs within the encoder stage. This can simplify channel-count arrangements, but the instrument designer must verify clocking, sync polarity, output loading, calibration, and DAC settling behavior against the manufacturer data sheet before instrument accuracy is claimed.
推荐
Industrial Video Inspection Systems
Industrial inspection systems that retain an analog video monitor can use the ADV7173KST as the output encoder between a digital image pipeline and a PAL or NTSC display. The device accepts CCIR-601 4:2:2 8-bit component video and provides six 10-bit DAC outputs for analog baseband generation. This is useful where existing operators use video monitors, although image-processing latency, interlacing requirements, noise susceptibility, and grounding should be evaluated at the system level.
推荐
Legacy Video Retrofit
A legacy-video retrofit module can combine a modern digital video source with an existing PAL or NTSC display by using the ADV7173KST as the encoder and analog-output converter. The six 10-bit DACs support multiple baseband video outputs from one 48-lead LQFP device. This is particularly useful for industrial, laboratory, and A/V maintenance systems where replacing the display would be impractical, while the retrofit board must still satisfy the signal timing and analog-output requirements of the original equipment.

设计说明
Route the CCIR-601 component-video inputs as a compact, length-matched group between the digital video source and the encoder, and keep the associated clock away from sensitive analog output paths. The verified excerpts do not provide recommended trace geometry or impedance values, so the final layout must follow the ADV7173 manufacturer data sheet and the host device's interface requirements.
Treat the six analog video outputs as potentially susceptible to digital clock and switching noise even though the encoder is described as having enhanced power management. Use a quiet supply reference, local high-frequency bypass, and separated return paths where practical. Confirm the required DAC output loading, termination, filtering, and allowed video bandwidth in Rev. B before finalizing the analog output network.
Do not substitute the ADV7173KSTZ solely because it appears in a direct comparison. Verify the complete 48-pin map, supply limits, clocking, register map, control behavior, temperature grade, and reel configuration. The verified material identifies the shared 48-lead LQFP format but does not establish every electrical and ordering difference needed for an unconditional drop-in qualification.
Use the manufacturer power-management controls and supply configuration when enabling or disabling the encoder because power-state transitions can affect system timing and analog outputs. Exact supply-voltage limits, quiescent current, and operating current were not available in the supplied excerpts. Confirm those values and sequencing requirements in the Analog Devices data sheet before selecting bypass capacitance or setting a system power budget.
合规信息
The supplied verified excerpts do not state RoHS, REACH, lead-free, halogen-free, or conflict-minerals status. AEC-Q100 is not applicable to the identified general-purpose PAL/NTSC video encoder application, but this field does not replace any separate qualification requirement.
