ADV7179WBCPZ-REEL

Overview

The ADV7179WBCPZ-REEL is a chip-scale PAL/NTSC video encoder manufactured by Analog Devices Inc. It converts digital CCIR-601 4:2:2 8-bit component video data into standard analog baseband television signals. The device features high-quality 10-bit video DACs and an integrated super sub-alias filter (SSAF). It supports NTSC M, PAL N2, PAL B/D/G/H/I, PAL-M3, and PAL 60 standards with a single 27 MHz clock requirement for standard operation. The unit operates on a single 2.8 V or 3.3 V supply and includes advanced power management features. It is housed in a small 40-lead 6 mm × 6 mm LFCSP package and is qualified for automotive applications under AEC-Q100 standards.

• Integrates SSAF technology to provide studio-quality video playback with optimal horizontal line resolution.
• Supports programmable luma and chroma filters, including low-pass, notch, CIF, and QCIF configurations.
• Includes onboard color bar generation, closed captioning support, and teletext insertion ports.

Applications

• Portable video applications
• Mobile phones
• Digital still cameras

Procurement Notes

Verify the specific ordering suffix against official documentation to confirm packaging type and reel specifications. Ensure the component meets regional regulatory requirements such as RoHS compliance before integration. Confirm that the intended operating voltage aligns with the selected supply configuration for optimal performance.

Selection Notes

Select this encoder when interfacing with digital video sources requiring conversion to analog TV standards. Consider the available output combinations, such as simultaneous composite and S-video, based on system design needs. Evaluate the required temperature range and power consumption constraints to ensure compatibility with the target application environment.

Part Context

This component belongs to the ADV7174/ADV7179 family of integrated digital video encoders. It shares functional similarities with other devices in the series but differs in specific feature sets like Macrovision support. The REEL suffix indicates the specific tape-and-reel packaging format used for automated assembly processes.

Replacement Considerations

Consult official manufacturer documentation for confirmed substitute part numbers. Verify pinout compatibility and electrical specifications before considering alternative components from different manufacturers.

FAQ
