ADV7320KSTZ - 216 MHz 6-DAC Video Encoder | Analog Devices
料号： ADV7320KSTZ ✓ 量产中ADV7320KSTZ 概述
A video encoder is an interface and signal-conversion integrated circuit that translates digital pixels into legacy or component analog video signals. Within the product hierarchy, the ADV7320KSTZ belongs to the video encoder and video DAC family of interface ICs. Its six high-speed NSV DACs provide separate or configurable analog channels, while the multiformat architecture supports professional broadcast, set-top-box, DVD, recording, and digital-display applications.
The device supports high-definition 4:2:2 and 4:4:4 parallel YCrCb input formats. Listed compatibility includes SMPTE 274M at 74.25 MHz, SMPTE 296M for 720p, and SMPTE 240M for 1035i. It also accepts 10-bit RGB 4:4:4 data. These formats allow the encoder to bridge digital video-processing pipelines to analog composite, S-Video, and component outputs without requiring separate external DAC banks.
The 216 MHz operating rate and six 12-bit DACs distinguish the ADV7320 from lower-rate encoders intended only for standard-definition video. The manufacturer describes enhanced performance and CGMS-A support for 625p output standards, helping conforming DVD players and recorders implement copy-protection signaling. Exact input timing, voltage, current, temperature, and DAC-output limits must be confirmed against the manufacturer datasheet before a production design is released.
Typical deployments include professional video routers, broadcast monitor interfaces, DVD and set-top-box output stages, video-recorder products, and professional playback equipment requiring multiple analog outputs. Because high-speed analog video signals are sensitive to impedance discontinuities, power-supply noise, grounding errors, and clock or data timing violations, the board layout should use controlled-impedance routing, short video traces, adequate return paths, and clean supply filtering.
A key design consideration is to preserve the supported digital timing and synchronization arrangement between the source device and the encoder. The ADV7320KSTZ is best suited to designs whose source can provide the documented pixel format, clocking, voltage levels, and timing rather than merely any generic parallel video interface. Its multiformat processing and integrated DAC count make it a strong fit for equipment that must generate several analog outputs from one digital video source.
This page consolidates the manufacturer product information, verified technical characteristics, package details, application guidance, and drop-in replacement analysis. It also highlights the need to verify every timing, electrical, and pin-level requirement against the current Analog Devices datasheet before using the encoder in new hardware.

典型应用
ADV7320KSTZ 适用于 6 应用s: Professional Broadcast Video Routing, Professional Video Monitoring, DVD and Set-Top-Box Output, Video Recording Equipment, Video Test and Measurement, Digital-to-Analog Video Interface Cards.
Professional Broadcast Video Routing
The ADV7320KSTZ fits professional video-routing and monitoring equipment that must translate a digital source into several legacy analog outputs. Its 216 MHz operating rate and six integrated 12-bit NSV DACs support multiformat generation of CVBS, S-Video, YPbPr, or RGB signals. The encoder can accept parallel 4:2:2 or 4:4:4 YCrCb and 10-bit RGB 4:4:4 data, reducing the number of discrete output converters required. For a reliable implementation, preserve source timing, use continuous ground references, and route the analog outputs as controlled-impedance lines. The advantage is integration: six converters and multiformat processing occupy one encoder package rather than several separate DAC and timing subsystems.
推荐
Professional Video Monitoring
The ADV7320KSTZ is appropriate for professional monitoring products requiring compatibility with composite, S-Video, or component displays. Its multiformat architecture produces CVBS, S-Video, YPbPr, and RGB from a common digital-video pipeline, while six 12-bit NSV DACs provide the converter resources for multichannel equipment. SMPTE 296M 720p and SMPTE 240M 1035i support broadens its usefulness in broadcast-related monitoring and signal-conditioning systems. Designers should separate noisy digital and switching paths from the analog outputs, maintain short return paths, and validate timing margins against the selected video mode before production release.
推荐
DVD and Set-Top-Box Output
The ADV7320KSTZ can serve as the analog-video output stage in DVD players, recorders, and set-top-box products. The manufacturer specifically identifies CGMS-A support for 625p output standards for copy-protection compliance in DVD equipment, while the six 12-bit DACs support multiple analog outputs. Its 4:2:2 and 4:4:4 parallel YCrCb inputs suit digital pipelines that already perform scaling and filtering. Choose this device when the product must retain a compact multiformat output section; verify the encoder configuration, source timing, DAC output assignment, and CGMS-A implementation against the manufacturer datasheet and applicable product requirements.
推荐
Video Recording Equipment
The ADV7320KSTZ is useful in analog-output recording and signal-conversion equipment that accepts a digital video stream and distributes it through composite, S-Video, or component channels. Six integrated 12-bit NSV DACs avoid a bank of discrete converters, while the 216 MHz architecture supports demanding multiformat operation. The design should account for analog-output settling, source clock relationship, and synchronization between recording and monitoring paths. High-speed video traces need continuous references and controlled impedance, and supply bypass components should be positioned directly at the relevant package pins. This arrangement is appropriate when product differentiation comes from flexible analog-output support rather than maximum channel count.
推荐
Video Test and Measurement
The ADV7320KSTZ can support video generation and format-conversion test equipment because it combines multiformat digital input handling with six high-speed analog DAC outputs. The 216 MHz rate and 12-bit converter resolution allow a test instrument to produce several legacy video standards from one digital source. A practical implementation should expose programmable operating modes, monitor generated outputs, and maintain deterministic timing between the digital source and encoder. Use controlled-impedance output layouts and provide clean references for analog measurement circuitry. This application is especially suitable when engineers need CVBS, S-Video, YPbPr, or RGB generation without assembling a bank of independent DAC modules.
推荐
Digital-to-Analog Video Interface Cards
The ADV7320KSTZ is well suited to interface cards that bridge digital video processors to legacy analog connectors. Its support for parallel YCrCb and 10-bit RGB 4:4:4 inputs allows the card to accept several common internal formats, while six 12-bit NSV DACs serve multiple analog outputs. This integration simplifies channel replication in rack-mounted playback, conversion, and processing equipment. The board layout should separate each analog output return path, minimize vias in sensitive video routes, and isolate converter supplies from digital switching activity. Before release, confirm the selected connector impedance, channel assignment, synchronization method, and supported output combination in the manufacturer documentation.

设计说明
Treat the six analog outputs as high-speed video paths rather than general-purpose low-frequency analog nets. Route each output over a continuous ground reference, avoid long stubs and unnecessary vias, and follow the manufacturer package and layout recommendations. Where connectors are used, keep the analog output section physically separated from switching regulators, clock circuitry, and high-current digital returns to reduce crosstalk and ground-noise coupling into the video outputs.
Use the supply voltage and decoupling arrangement specified in the Analog Devices datasheet. Place required bypass capacitors immediately at the associated power pins, provide adequate return vias, and isolate sensitive analog sections from noisy switching nodes where the reference layout permits. The available product summary confirms TTL-compatible video inputs but does not state the supply range, so supply voltage and capacitor values must be selected from the manufacturer document rather than inferred from the 216 MHz clock rate.
Preserve the timing relationship between the digital pixel data, synchronization signals, and encoder clock. Review setup and hold requirements for the selected 4:2:2, 4:4:4 YCrCb, or 10-bit RGB mode, and avoid adding unnecessary logic or stubs between the source and encoder. Because the part supports several video standards, a design intended for one SMPTE mode should not assume that timing and output settings from another mode are interchangeable.
Do not treat family similarity as proof of interchangeability. Before replacing the ADV7320KSTZ, compare the complete pin list, supply requirements, exposed-pad connection, digital timing, configuration interface, DAC channel mapping, synchronization inputs, and reset behavior. The ADV7322KSTZ has the strongest package-and-terminal consistency in the available cross-reference material, but production substitution still requires manufacturer-datasheet review and board-level validation.
