ADV7305AKST - 6-Channel 14-Bit Video Encoder | Analog Devices
MPN： ADV7305AKST ✗ 停產ADV7305AKST 概覽
A video encoder is a signal-conversion integrated circuit that accepts digital video data and produces analog video outputs suitable for downstream display, broadcast, or video-processing equipment. In the broader signal-chain hierarchy, the ADV7305AKST combines a video encoder with digital-to-analog conversion, placing it between digital video sources and analog video outputs.
The principal features of the ADV7305AKST are its multiformat SD and progressive-scan or HDTV support, six integrated 14-bit DAC channels, and 14-bit video encoding capability. The six DACs allow a design to produce multiple analog video outputs without requiring separate external converter packages. The part also supports both analog and digital supply rails identified as 2.5 V.
The device is intended for DVD, SD, and HD video equipment, including multiformat video generation systems. Its integrated six-channel DAC architecture simplifies analog-output implementation by keeping encoding and conversion within one package. The 64-LQFP package is intended for surface-mount assembly and provides a clearly defined board-level footprint for equipment with multiple video outputs.
Typical applications include SD video encoding, progressive-scan video generation, HDTV signal generation, DVD-related video systems, and professional or industrial video equipment requiring several analog outputs. The ADV7305AKST is particularly relevant when the source subsystem already produces digital video and the destination equipment expects multiple analog video signals.
PCB implementation should account for the device's multi-output analog architecture and the need to route video signals away from sensitive digital paths. Use the manufacturer's pin-description table when assigning connector and routing-related pins, and follow the analog and digital grounding recommendations in the ADV7305AKST datasheet. Power decoupling should follow the datasheet's recommended network for both 2.5 V analog and digital supplies.
This page organizes the ADV7305AKST's encoder and DAC functions, package information, application roles, and design considerations into a practical engineering reference. It also distinguishes verified device facts from optional same-footprint selection criteria, helping engineers assess replacements without confusing shared packaging with guaranteed electrical equivalence.

典型應用
ADV7305AKST 適用於 6 應用s: SD Video Encoding, Progressive-Scan Video Generation, HDTV Video Output, DVD Video Equipment, Professional Video Test Equipment, Industrial Video Processing.
SD Video Encoding
The ADV7305AKST fits SD video-generation equipment because the Analog Devices device supports multiformat SD encoding and provides six 14-bit DAC output channels. It can convert a digital video source into analog video signals while reducing the number of separate converter packages required on the board. The 2.5 V analog and 2.5 V digital supplies should be decoupled according to the manufacturer application circuit. Confirm the required SD pixel format, synchronization method, output connector and timing limits in the datasheet before implementation.
Progressive-Scan Video Generation
The ADV7305AKST is appropriate for progressive-scan video systems that need multiformat encoding and several analog outputs from one device. Its 14-bit encoder and six 14-bit DACs provide a unified path from digital video processing to analog signal generation. This consolidation can simplify board partitioning compared with using separate output converters. The layout should preserve signal integrity by following the recommended analog grounding, supply-return and output-routing arrangements in the manufacturer datasheet.
HDTV Video Output
The ADV7305AKST supports HDTV video encoding, making it relevant to HD video generators, broadcast equipment and professional monitoring systems that require analog outputs. Six integrated 14-bit DAC channels allow multiple video destinations to be supported without adding six discrete converter packages. Engineering validation should cover the required HD timing format, synchronization interfaces, output amplitude specifications and connector loading. Use the datasheet timing and application diagrams to determine the final output network and routing.
DVD Video Equipment
DVD and related multimedia equipment can use the ADV7305AKST where multiformat SD or HD video generation and multiple analog outputs are required. The six 14-bit DACs integrate directly with the encoder function, providing a compact path to analog video connectors. The 64-lead LQFP also offers a defined surface-mount footprint for production equipment. Designers should verify the DVD-related source format, supported synchronization signals and output circuitry against the manufacturer documentation before finalizing the architecture.
Professional Video Test Equipment
The ADV7305AKST is suited to professional video test and signal-generation equipment that must create several analog outputs from a digital video source. Its six-channel 14-bit DAC architecture enables multi-output test configurations within one device, while multiformat SD, progressive-scan and HDTV support broadens instrument coverage. Signal integrity remains the central implementation concern: keep analog outputs controlled, separate sensitive returns from digital activity and follow the manufacturer's recommended decoupling and grounding arrangements.
Industrial Video Processing
Industrial imaging and video-processing equipment can employ the ADV7305AKST when a system includes digital video generation and needs multiple analog outputs for monitors, recorders or downstream processors. The six integrated 14-bit DACs reduce the number of discrete output-conversion components and keep the signal chain compact. Industrial implementations should still validate operating-temperature limits, EMC requirements and long-term availability against the current manufacturer documentation. For production use, confirm lifecycle status and obtain a quotation for the exact ordering code and required quantities.

設計說明
Use the manufacturer pin-description table and application schematic to assign all 64 LQFP terminals before layout. The ADV7305AKST combines a 14-bit video encoder, six 14-bit DAC channels, 2.5 V analog and digital supplies, and numerous control or synchronization signals. Keep analog and digital return paths disciplined, and avoid treating the package as a generic video encoder because the six analog outputs materially change routing and grounding requirements.
Route the six analog video outputs as controlled transmission paths and keep them away from digital video, clock and switching-current nodes. Apply the output-network values and termination arrangement specified by the Analog Devices datasheet for the intended video format. The 14-bit DAC resolution does not guarantee acceptable picture quality if noise, impedance discontinuities or return-current paths corrupt the analog signal.
Provide separate 2.5 V analog and 2.5 V digital rails as specified for the ADV7305AKST. Place the required bypass capacitors close to their associated supply pins and follow the manufacturer decoupling and layout diagrams exactly. Check capacitor voltage ratings, tolerance and effective capacitance at the operating frequency, and route high-current return paths away from sensitive analog-output references to reduce supply-induced video artifacts.
