ADV7314KST - 216 MHz Video Encoder with Six 14-Bit DACs | Analog Devices
料号： ADV7314KST ✗ 停产ADV7314KST 概述
A video encoder is an interface IC that converts digital component video into one or more analog output signals. The ADV7314KST belongs to the broader DAC and video-encoding hierarchy: digital video data enters through parallel YCrCb inputs, internal encoding and DAC circuitry generate composite or component outputs, and the resulting analog signals drive downstream display or broadcast equipment. Its 14-bit DAC resolution provides a defined numerical output-resolution characteristic for professional video systems.
Key features include six 14-bit NSV video DACs, a 216 MHz operating specification, and parallel YCrCb input compatibility. The device supports both 4:2:2 and 4:4:4 high-definition input formats. Multiple listed television standards provide defined support for 525-line and 625-line systems, including SMPTE 293M, BTA EDTV2, ITU-R BT.1358, and ITU-R BT.1362. The 64-lead LQFP package supports surface-mount assembly and is identified as lead-free.
Technically, the ADV7314KST combines digital video processing with six high-speed, multiformat NSV digital-to-analog converters. This integration reduces the number of discrete DAC channels required in a multichannel analog-video design. The 216 MHz headline specification identifies the device as intended for high-speed video processing, while the six-DAC configuration allows multiple video outputs to be generated from one package. Exact output current, DAC noise, power-supply limits, temperature limits, and timing values are not present in the supplied verified records and should be confirmed in the manufacturer datasheet before design release.
Typical uses include professional broadcast video conversion, standard-definition television equipment, high-definition production electronics, video test and measurement systems, and digital-to-analog video processing modules. The 4:2:2 and 4:4:4 input support makes it relevant to systems handling subsampled and full-resolution chroma video. Six integrated DACs can reduce board area when the design requires six analog video channels rather than separate converter packages.
Designers should confirm the exact pin assignments, output-routing options, synchronization requirements, supply rails, decoupling recommendations, and analog-video output topology against the ADV7314 manufacturer datasheet. PCB layout should preserve controlled clock and digital-video signal paths while providing a low-impedance return for each DAC output. Because the supplied search results do not provide a verified price, stock quantity, complete pinout, or detailed electrical limits, those items should not be inferred from generic distributor listings.
This product page consolidates the verified multiformat 216 MHz specification, six 14-bit NSV DAC configuration, supported video standards, package information, source links, and same-family replacement guidance. It also distinguishes verified features from unavailable parameters and provides selection and comparison context that is not contained in the short distributor snippets.

典型应用
ADV7314KST 适用于 6 应用s: Professional Broadcast Video Conversion, 525-Line Television Equipment, 625-Line Television and Broadcast Systems, High-Definition Video Processing Modules, Video Test and Measurement Systems, Digital-to-Analog Video Processing.
Professional Broadcast Video Conversion
The ADV7314KST fits broadcast video conversion because it combines a 216 MHz multiformat encoder with six 14-bit NSV DAC outputs. Its parallel YCrCb interface accepts 4:2:2 and 4:4:4 high-definition data, while the listed SMPTE 293M, BTA EDTV2, ITU-R BT.1358, and ITU-R BT.1362 support covers defined 525-line and 625-line applications. Integrating six DAC channels on one device can reduce board area versus discrete converter designs. The key design trade-off is that exact output timing, synchronization, and analog-video routing must be verified from the manufacturer datasheet before studio equipment is released.
推荐
525-Line Television Equipment
The ADV7314KST supports SMPTE 293M 525p and BTA EDTV2 525p formats, making it applicable to legacy and professional 525-line television signal chains. Its six 14-bit NSV DACs can provide multiple analog video outputs while a parallel YCrCb source supplies digital component video. Using one multichannel encoder package may simplify synchronization and board allocation compared with several separate DAC assemblies. However, designers must confirm the selected output mode, sync behavior, clock source, and whether the target television standard requires additional filtering or conditioning not specified in the supplied search records.
推荐
625-Line Television and Broadcast Systems
The ADV7314KST is suitable for 625-line systems because its verified standard list includes ITU-R BT.1358 and ITU-R BT.1362 at 625p. The 216 MHz operating specification provides the core high-speed video capability, while six 14-bit DACs support multichannel analog output generation from one 64-lead LQFP. Parallel YCrCb 4:2:2 or 4:4:4 input selection should be matched to the upstream frame store or video processor. Engineers must still validate blanking intervals, sync polarity, output amplitude, and channel mapping against the current manufacturer documentation.
推荐
High-Definition Video Processing Modules
The ADV7314KST fits modular HD video processing where parallel YCrCb data enters in either 4:2:2 or 4:4:4 form and analog outputs are required downstream. Its six 14-bit NSV DAC channels allow a compact module to cover multiple video outputs without using six separate DAC packages. The architecture is particularly relevant to production monitors, video routers, frame converters, and signal-generation equipment. A key engineering consideration is routing high-speed digital inputs away from sensitive analog outputs, while providing local decoupling and controlled return paths for predictable DAC behavior.
推荐
Video Test and Measurement Systems
The ADV7314KST can be used in video test equipment that requires a controlled multiformat encoder with six analog output channels. Its 216 MHz specification and support for SMPTE 293M, BTA EDTV2, ITU-R BT.1358, and ITU-R BT.1362 make it relevant to waveform generation, video-route testing, and broadcast-format conversion. Six integrated 14-bit NSV DACs may simplify multi-output test fixtures, but the test system must provide a stable reference clock and correct timing configuration. Confirm allowable sync patterns, output enable behavior, and calibrated output levels before integrating it into automated compliance equipment.
推荐
Digital-to-Analog Video Processing
The ADV7314KST is specifically suited to digital-to-analog video conversion because it combines digital encoding stages with six NSV DACs rated at 14-bit resolution. A parallel YCrCb source can feed the supported 4:2:2 or 4:4:4 input path, avoiding a separate DAC bank when six channels are required. The 64-lead LQFP provides a surface-mount implementation suitable for multichannel boards. The performance trade-off is integration density rather than universal input compatibility: source timing, chroma interpretation, and DAC-output configuration must match the original design, so direct substitution requires a full pin and functional comparison.

设计说明
Keep the 216 MHz digital-video interface and clock paths away from the six DAC output regions. Use a continuous ground reference, avoid routing YCrCb data beneath analog outputs, and provide a low-impedance return for every output channel. The supplied records do not contain the manufacturer's recommended layout artwork, so obtain the complete datasheet and evaluation-board guidance before finalizing trace spacing, return paths, and analog-output isolation.
Treat clock, sync, and parallel YCrCb inputs as a coordinated high-speed interface. Match routing to the device's documented clock topology, keep clock and data skew within the manufacturer limits, and use a suitable source termination strategy where required. The verified data confirms 216 MHz operation and parallel YCrCb input but does not provide edge-rate, impedance, or skew limits, so those values must be obtained from the authoritative datasheet rather than estimated.
Do not assume that a 64-lead package makes every related encoder a direct substitute. ADV7321KSTZ and ADV7324KSTZ use different characterized input-port architectures, ADV7311KST has lower DAC resolution, and BH6900KUT uses a TQFP package description. Before replacing ADV7314KST, compare every power, ground, clock, synchronization, digital-input, and DAC-output pin, then confirm supported timing and video standards.
Determine the ADV7314KST's actual supply rails, supply-current profile, and allowed decoupling from the manufacturer datasheet before laying out the power network. Six high-speed DACs may require careful partitioning of analog and digital supply return paths, but no verified rail values or current limits were supplied. Avoid deriving capacitor values or power budgets from generic encoder data; use the device-specific recommended operating circuit and thermal information.
合规信息
The verified JAK Electronics result identifies ADV7314KST as lead-free and names the MS-026BCD 64-lead LQFP package. No explicit RoHS, REACH, halogen-free, conflict-minerals, or automotive-qualification statement was supplied.
