ADV7390WBCPZ - 10-Bit SD/HD Video Encoder | Analog Devices
Артикул: ADV7390WBCPZ ✗ Снят с производстваADV7390WBCPZ Обзор
A video encoder is a mixed-signal semiconductor that translates digital pixels into standard-definition analog video waveforms. Within the signal-chain hierarchy, the ADV7390 belongs to the video-processing IC class and ultimately to the broader data-converter and signal-processing IC category. Its integrated DAC architecture combines digital timing generation, clock recovery, color processing, and analog output stages to reduce the component count required for composite-video output.
Three 2.7 V or 3.3 V video DACs provide the core analog outputs. The encoder supports composite and S-Video operating modes, while a 16-times or 4-times oversampling PLL supports internal clock generation from the digital video interface. Power-management controls support low-power operation, and the device includes cable-detection capability. The family documentation also identifies synchronization controls for reset, horizontal sync, and vertical sync.
The ADV7390 architecture is organized around a video timing generator, an 11-bit internal DAC datapath, a three-channel output multiplexer, and a reference and cable-detect section. Although the device is marketed as a 10-bit video encoder, the internal DAC structure includes an 11-bit stage, allowing the encoder to generate composite CVBS and S-Video outputs with reduced intermediate digital processing.
Typical deployments include DVD players, game consoles, media players, industrial video equipment, and legacy analog-video conversion products. The small 5 mm by 5 mm LFCSP package supports compact consumer-electronics layouts, although careful decoupling and thermal design remain necessary around the analog output circuitry.
When designing a new product, confirm that the ADV7390 is appropriate for the target channel standard and system lifecycle because Analog Devices marks it as not recommended for new designs. Existing equipment can still benefit from its three-DAC integration, but new platforms should evaluate current encoder families when long-term supply is a priority.
This page combines manufacturer documentation, lifecycle information, drop-in family alternatives, package guidance, and application-oriented engineering notes to support board-level sourcing and design decisions.

Типичное применение
ADV7390WBCPZ подходит для 6 применениеs: DVD Player Video Output, Game Console Composite Video, Media Player Video Conversion, Industrial Video Conversion Retrofit, Analog Video Test Equipment, Legacy Consumer Equipment Repair.
DVD Player Video Output
The ADV7390WBCPZ fits legacy DVD-player designs that require composite CVBS and S-Video Y-C outputs from a digital video interface. Its three integrated DACs avoid the need for three separate output converters, while the internal video timing generator and 16x or 4x oversampling PLL simplify clock and synchronization arrangements. The 32-lead 5 mm by 5 mm LFCSP also supports compact consumer-electronics layouts. Before redesigning an existing DVD board, verify that the target player uses a supported standard-definition mode and that the original firmware configuration can be reproduced with the selected encoder family member.
Рекомендуется
Game Console Composite Video
The ADV7390WBCPZ can support legacy game-console accessories that provide composite video or S-Video from a digital graphics pipeline. Its three DAC channels allow the same encoder to serve multiple analog output modes, while the low-power chip-scale architecture suits space-constrained console electronics. Integration reduces analog output component count, but the timing and filtering configuration must match the target graphics standard. Use the manufacturer family data sheet to confirm synchronization behavior, clock requirements, and output mapping before placing the device into a new accessory design.
Рекомендуется
Media Player Video Conversion
The ADV7390WBCPZ is appropriate for legacy media-player electronics that must convert digital video into composite or S-Video for televisions, projectors, and recording accessories. Its three integrated DACs and internal timing block reduce the board area associated with discrete output conversion. The principal design trade-off is lifecycle: because Analog Devices marks the encoder as not recommended for new designs, repair and expansion programs are better candidates than newly launched products. For new hardware, compare the required output standard and production volume against currently recommended encoder families.
Рекомендуется
Industrial Video Conversion Retrofit
The ADV7390WBCPZ can be used in industrial video-retrofit equipment that bridges a digital video source to legacy composite or S-Video monitors. Its integrated DACs and timing generator support a compact multi-output analog interface, which is useful where three separate video DACs would increase cost and board space. The design must still account for analog-output routing, reference stability, cable detection, and synchronization. Because this is a not-recommended-for-new-designs component, use it primarily where replacing the original encoder minimizes recertification and software-validation effort.
Рекомендуется
Analog Video Test Equipment
The ADV7390WBCPZ is suitable for legacy video-generation test equipment because it combines three DAC outputs with digital timing and PLL functions on one chip. This allows an instrument to produce composite and S-Video test patterns from a digital source without a large collection of discrete output stages. Stable external clocking, reference design, and DAC-output calibration are central to accurate signal generation. Evaluate each family member for the exact standards, test-pattern capability, and calibration requirements rather than relying only on package compatibility.
Рекомендуется
Legacy Consumer Equipment Repair
The ADV7390WBCPZ is particularly relevant to repair lines for DVD players, game consoles, and media players that use the original 32-lead encoder. Matching the package, pin arrangement, and supported output modes reduces mechanical and schematic changes during board repair. Its not-recommended-for-new-designs status should be handled as a continuity-planning consideration: confirm date codes, traceability, and lifecycle support for the volume being repaired. The automotive-oriented ADV7390BCBZ-A-RL may serve related programs when its qualification documentation meets the end-product requirement.

Заметки по проектированию
Place the analog-supply decoupling capacitors immediately beside their associated supply pins and keep the three DAC output routes short and symmetric. The family data sheet identifies separate analog, core, and digital I/O supply domains; route each decoupling return directly to the appropriate ground reference. Keep the external reference and cable-detect components away from digital timing nets to reduce conversion of switching noise into visible analog artifacts.
Treat the CLKIN, RESET, HSYNC, and VSYNC connections as timing-critical interfaces even though the device is an analog-output encoder. Route clock signals away from the DAC outputs and reference network, maintain a continuous ground reference beneath the LFCSP, and confirm pull-up or pull-down values against the manufacturer pin-description table. A stable clock reference is essential because the internal 16x or 4x oversampling PLL reconstructs the sampling timing used by the video DACs.
Do not treat the ADV7390, ADV7391, ADV7392, and ADV7393 packages as interchangeable merely because they use the same 32-LFCSP footprint. Match the supported video standard, DAC-output assignment, register map, synchronization behavior, and software configuration before substitution. Also account for the product's not-recommended-for-new-designs lifecycle status when planning production continuity or a repair program.
Use the manufacturer's evaluation-board layout as the starting point for component placement and analog routing. Preserve the recommended spacing around the exposed pad and thermal-via pattern, and follow the reference-layout guidance for the 5 mm by 5 mm LFCSP. Digital input routing should approach the encoder from the logic side while the three video DAC outputs leave toward the connector region, minimizing overlap between high-speed digital edges and sensitive analog outputs.
Информация о соответствии
Compliance attributes were not stated in the manufacturer or distributor information for this ordering code. The ADV7390BCBZ-A-RL ordering code is associated with an automotive-oriented family option, but AEC-Q100 qualification status should be confirmed from its automotive product documentation before use in a vehicle application.
