ADV7179BCP

Overview

The ADV7179BCP 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 SSAF™ super sub-alias filter for studio-quality playback. It supports NTSC M, PAL N2, PAL B/D/G/H/I, PAL-M3, and PAL 60 standards using a single 27 MHz clock with ×2 oversampling. The encoder includes advanced power management, CGMS, WSS, and closed captioning support. It operates on a single 2.8 V or 3.3 V supply and is housed in a compact 40-lead 6 mm × 6 mm LFCSP package.

Feature Summary

• Converts digital YCrCb data to analog composite, S-video, or component outputs
• Integrates SSAF™ technology for enhanced horizontal line resolution
• Supports multiple global broadcast standards including NTSC and PAL variants
• Includes programmable luma and chroma filters for signal optimization

Applications

• Portable video applications
• Mobile phones
• Digital still cameras

Procurement Notes

Verify the specific revision level (Rev. D) against current manufacturing records. Confirm that the LFCSP-40 package matches the target PCB footprint. Ensure the design accommodates the exposed pad grounding requirements for thermal dissipation and noise reduction as specified in the datasheet outline dimensions.

Selection Notes

Select this component when a small form factor is required for mobile or portable devices. Choose the ADV7179 over the ADV7174 if Macrovision 7.1 anticopy protection is not needed. Verify that the system can provide the required 27 MHz reference clock or alternative square pixel clocks. Ensure the application utilizes the I2C-compatible serial interface for register configuration.

Part Context

This part belongs to the ADV7174/ADV7179 family of integrated digital video encoders. It shares the same physical package and core functionality with the ADV7174, differing primarily in the inclusion of Macrovision licensing features. The device is designed for low-power consumer electronics requiring high-fidelity video encoding from digital sources.

Replacement Considerations

The ADV7174BCP is a functional substitute within the same family. Verify that the absence of Macrovision 7.1 support in the ADV7174 meets the specific regulatory requirements of the end product.
