ADV7179KCPZ - 10-Bit PAL/NTSC Video Encoder | Analog Devices
MPN: ADV7179KCPZ ✗ Cuối đờiADV7179KCPZ Tóm tắt
A video encoder is an interface and signal-conversion IC positioned between digital video sources and analog display systems. It accepts digital luminance and chrominance data, applies the timing and encoding required for composite video, and produces analog television outputs. In the product hierarchy, the ADV7179KCPZ is an analog video encoder, interface IC, signal-conversion IC, and semiconductor.
The principal features include ITU-R BT.601/BT.656 YCrCb input support, conversion to PAL or NTSC video, three integrated 10-bit DACs, and 2-wire serial control. The two available slave addresses allow the host processor to distinguish or access the ADV7174 and ADV7179 operating modes. Analog Devices identifies the encoder for digital-camera, mobile-phone, and portable-video applications.
Internally, the encoder accepts digital YCrCb component data derived from a digital video source and generates analog baseband television signals compatible with worldwide television standards. Integrating three DACs reduces the number of external video-output conversion stages required in a compact design. The 40-pin exposed-pad LFCSP also supports improved heat dissipation when its exposed pad and PCB land pattern are implemented correctly.
Typical uses include composite-video output for security cameras, camera modules, portable media equipment, and mobile-phone accessories. It can also be evaluated in industrial imaging and legacy video-conversion equipment when the system must generate PAL or NTSC output from a digital YCrCb source. The I2C-compatible control path simplifies configuration in designs that already include a digital video controller.
Designers should verify the exact pin names, exposed-pad connection, analog output impedance, external network requirements, and supply sequencing against the manufacturer datasheet before layout release. Because the ADV7179 family is marked “NOT RECOMMENDED FOR NEW DESIGNS,” long-life products should normally use a currently recommended encoder unless an existing platform requires its established function and interface.
This page combines the exact package and product identifiers, lifecycle position, functional characteristics, application guidance, and verified sourcing context for the ADV7179KCPZ. It also distinguishes confirmed device facts from specifications that require the manufacturer datasheet before schematic or PCB sign-off.

Ứng dụng tiêu biểu
ADV7179KCPZ phù hợp cho 6 Áp dụngs: Security Camera Composite Video, Digital Camera Module, Mobile Phone Video Accessory, Portable Video Equipment, Industrial Imaging Interface, Legacy Video Conversion.
Security Camera Composite Video
The ADV7179KCPZ fits legacy analog CCTV designs that receive digital YCrCb video from an imaging pipeline but must transmit composite PAL or NTSC output to a monitor, recorder, or controller. Its three integrated 10-bit DACs reduce the number of separate output-conversion stages, while the 2-wire serial interface permits configuration from the camera’s main processor. The 40-lead LFCSP-VQ package also permits compact board placement when the exposed-pad layout follows the manufacturer recommendations. Because the family is not recommended for new designs, this application is most appropriate for an established product or a controlled reuse of an existing platform.
Digital Camera Module
In a digital camera module, the ADV7179KCPZ can provide an analog PAL or NTSC output when a downstream display or capture product requires legacy television signaling rather than a digital video interface. The encoder accepts CCIR-601 4:2:2 8-bit YCrCb data and supports ITU-R BT.601/BT.656 timing, which allows it to operate downstream of a digital imaging and color-processing block. Its three 10-bit DACs support analog generation within one IC, while the two-slave-address control arrangement simplifies mode management. System designers should verify analog output network requirements and thermal performance in the final enclosure.
Mobile Phone Video Accessory
The ADV7179KCPZ can be evaluated in a mobile-phone or accessory design that must convert a digital video stream into PAL or NTSC for an external display, docking product, or capture accessory. Its digital input and I2C-compatible control path suit systems already processing YCrCb video data, and the three integrated 10-bit DACs provide a compact analog-output path. The commercial temperature grade and package size support space-conscious portable electronics when operating conditions remain within the datasheet limits. Because the device is not recommended for new designs, a new platform should compare it with a currently supported encoder before committing to the architecture.
Portable Video Equipment
Portable video equipment can use the ADV7179KCPZ when it needs a compact conversion from digital YCrCb component data to a PAL or NTSC composite-video output. The integrated three-DAC arrangement avoids implementing three separate 10-bit output converters, and the 2-wire serial control interface permits compact integration with a portable media controller. Its 40-lead, 6 mm × 6 mm LFCSP-VQ package supports surface-mount assembly but requires a correctly designed exposed-pad land pattern. Engineers should confirm startup behavior, output-network values, and synchronization at the intended line rate using the manufacturer application information.
Industrial Imaging Interface
The ADV7179KCPZ is applicable to industrial imaging systems that retain an analog PAL or NTSC output for legacy monitors, machine-vision displays, or service interfaces. The encoder accepts digital CCIR-601 4:2:2 YCrCr component video and converts it into standard analog baseband television signals through three 10-bit DACs. Its I2C-compatible 2-wire interface allows the system controller to select and configure the operating mode. For equipment expected to remain in service for many years, check lifecycle availability and consider a currently recommended encoder because the ADV7179 family is not recommended for new designs.
Legacy Video Conversion
The ADV7179KCPZ can bridge a modern digital video pipeline to a legacy PAL or NTSC display in equipment upgrade and format-conversion projects. Accepting ITU-R BT.601/BT.656 YCrCb data allows the encoder to sit after a digital scaler or frame-processing stage, while three integrated 10-bit DACs produce the required analog channels. The 2-wire serial interface simplifies configuration and can coexist with the host processor’s other control functions. The design should verify whether the target requires composite video, S-Video, or another output arrangement by consulting the complete pin and application information.

Ghi chú thiết kế
Implement the exposed pad and its thermal-via pattern exactly as shown in the manufacturer package drawing and land-pattern guidance. The ADV7179KCPZ uses a 40-lead 6 mm × 6 mm LFCSP-VQ package, so a generic 40-pin QFN footprint must not be assumed to match. Confirm pad dimensions, pin numbering, solder-mask policy, and exposed-pad connection from the package drawing before releasing the PCB artwork.
Route digital video inputs and the 2-wire control interface away from the analog video outputs, especially when the encoder drives external composite-video networks. Use the shortest practical digital connections, provide continuous reference planes, and place any required input or output network components close to their associated pins. Verify timing margins against the applicable ITU-R BT.601/BT.656 interface conditions rather than relying only on nominal clock frequency.
Treat the exposed pad as part of the thermal and electrical design. Estimated: if the encoder dissipates 1 W and the assembled package-to-ambient thermal resistance is 40 C/W, the estimated junction-temperature rise is 40 C above ambient; substitute the actual board-level thermal resistance and measured dissipation for your construction. Provide copper and thermal vias under the exposed pad when the manufacturer layout recommendation supports them, then verify temperature rise in the final enclosure.
