ADV7390BCPZ - 10-Bit SD/HD Video Encoder | Analog Devices
MPN： ADV7390BCPZ ✗ 停產ADV7390BCPZ 概覽
A video encoder is an interface integrated circuit that translates digital pixel data into analog video waveforms. Within the broader signal-processing hierarchy, the ADV7390BCPZ combines digital-to-analog conversion, filtering, output-driver circuitry, and video-timing control. Its three converter channels support composite and S-Video output formats, allowing multiple standard-definition signals to be generated from one compact device.
The principal advantages are the 10-bit conversion resolution, integration of three video DACs, operation from 2.7 V or 3.3 V, and low-power chip-scale construction. The 5 mm by 5 mm LFCSP-VQ package reduces board area compared with discrete video-output circuitry. Its three-channel architecture also simplifies analog routing while preserving separate outputs for composite and Y-C video signals.
Analog Devices describes the device as a high-speed digital-to-analog video encoder suitable for SD and HD video encoding. The manufacturer datasheet contains configuration, register, timing, and electrical details needed for firmware and hardware implementation. Designers should use the register descriptions and timing diagrams when configuring output formats, blanking levels, sync generation, and power-control behavior.
Typical uses include DVD players, game consoles, media players, set-top equipment, video test systems, and industrial or professional video products that require standardized analog video outputs. The ADV7390BCPZ is particularly appropriate where multiple analog video channels, compact PCB area, and 10-bit output resolution are more important than support for new video-encoder designs.
The principal design consideration is package and power planning. The LFCSP-VQ footprint requires careful pad layout, thermal-via placement, and clean analog routing around the video outputs. Power-supply design must accommodate the specified 2.7 V or 3.3 V operating condition, while the application circuit should follow Analog Devices reference guidance for decoupling, grounding, and output-network implementation.
This product page combines the manufacturer specifications, sourcing information, interface guidance, and application-oriented design guidance for engineers evaluating the ADV7390BCPZ. Because Analog Devices marks the device as not recommended for new designs, it is best suited to maintaining existing SD or HD video products, repairing established equipment, or supporting a legacy platform with controlled lifecycle requirements.

典型應用
ADV7390BCPZ 適用於 6 應用s: DVD Player Video Output, Game Console Legacy Video Interface, Media Player Analog Output, Professional Video Test Equipment, Industrial Video Control Console, Video Security and Surveillance Retrofit.
DVD Player Video Output
The ADV7390BCPZ fits legacy DVD-player designs that generate composite CVBS or Y-C analog video from digital pixel data. Its three 10-bit DAC channels provide multiple analog outputs in one 5 mm by 5 mm package, reducing the converter count and board area needed for video generation. Use the manufacturer timing and reference-circuit guidance for sync, blanking, filtering, and output networks. Because the encoder is not recommended for new designs, it is most appropriate for maintaining an existing qualified platform rather than initiating an unrestricted consumer-product redesign.
推薦
Game Console Legacy Video Interface
The ADV7390BCPZ is appropriate for maintaining a legacy game-console or video-adapter platform that requires standardized composite and Y-C outputs. Three integrated 10-bit converter channels support the video DAC stage without requiring three separate converter packages, while operation from 2.7 V or 3.3 V supports common mixed-signal supply arrangements. Preserve the established firmware, timing, grounding, and output filtering to avoid picture-quality changes. Validate synchronization and compliance on the target display equipment before authorizing field deployment.
推薦
Media Player Analog Output
A media player with legacy composite or S-Video connectivity can use the ADV7390BCPZ to consolidate its analog video conversion into a compact, low-power circuit. The three 10-bit DAC channels suit multiple video outputs, and the 32-lead LFCSP-VQ footprint limits board occupancy in compact set-top or portable-media designs. Follow the Analog Devices application guidance for decoupling, reference grounding, and output termination. For new platforms, first evaluate whether a newer encoder better satisfies lifecycle and interface requirements.
推薦
Professional Video Test Equipment
The ADV7390BCPZ can serve as the video-output stage in legacy SD or HD video test and signal-generation equipment. Its three 10-bit DAC channels permit multiple analog outputs, while the low-power chip-scale package supports dense instrumentation layouts. The design must follow the manufacturer timing, register, and reference-circuit guidance to preserve intended video amplitude, synchronization, and spectral performance. Treat it as a maintenance-oriented choice because Analog Devices marks the device as not recommended for new designs.
推薦
Industrial Video Control Console
For an established industrial video-control console that transmits composite or Y-C signals, the ADV7390BCPZ provides a compact three-channel, 10-bit encoding solution. The 5 mm by 5 mm LFCSP-VQ package reduces board-area impact compared with discrete converter implementations, and the low-power architecture suits continuously operating equipment. Verify the specified supply range, thermal conditions, output timing, and interface isolation for each industrial deployment. Use the approved engineering change process to maintain production consistency.
推薦
Video Security and Surveillance Retrofit
The ADV7390BCPZ is suitable for retrofitting a legacy surveillance or video-distribution controller that requires composite video output from a digital video source. Its three integrated 10-bit converter channels can support the required analog output stages while conserving board area, and the low-power construction fits permanently installed equipment. Maintain the established clocking, register configuration, filtering, and grounding to prevent visible image degradation. Confirm operating-environment requirements and supply continuity before using the encoder in a new surveillance program.

主要差異化特點
- Three integrated 10-bit video DAC channels (對比ADV7390WBCPZ)
- Compact 32-lead video encoder package (對比ADV7391BCPZ)
- Purpose-defined ADV7390 legacy platform support (對比ADV7282WBCPZ-M)
設計說明
Use the 32-lead LFCSP-VQ land pattern and exposed-pad information in the manufacturer package drawing. Place input, output, and decoupling connections directly at the associated pins to minimize loop area. Confirm thermal-via geometry against the package dimensions because an incorrect via arrangement can impair heat transfer from the exposed pad and change the intended electrical behavior.
Route the three analog video outputs away from digital control signals and clocks, and follow the manufacturer reference-circuit topology for grounding and output filtering. Keep sensitive timing and register-control traces away from the video output paths. The analog output network should be copied from the validated application circuit because component selection and return paths can affect video quality.
Plan the supply rails around the specified 2.7 V or 3.3 V operating condition and the device-specific digital and analog requirements in the datasheet. Place the recommended bypass capacitors close to their power pins and observe the sequencing requirements for the analog and digital rails. Validate startup, shutdown, and current consumption across the complete firmware operating sequence rather than relying only on steady-state measurements.
Do not treat same-package alternatives as equivalent without checking pin descriptions, register compatibility, timing, output modes, and operating conditions. In particular, confirm the advanced features and lifecycle status of ADV7390WBCPZ and ADV7391BCPZ against the ADV7390 documentation. Preserve the established configuration when maintaining an existing design to avoid changing blanking, sync, filtering, or output behavior unintentionally.
