ADV7174WBCPZ

Overview

The ADV7174WBCPZ is a chip-scale PAL/NTSC video encoder that converts digital CCIR-601 4:2:2 8-bit component video data into standard analog baseband television signals. It features high-quality 10-bit video DACs and an integrated SSAF™ super sub-alias filter for studio-quality playback. The device supports NTSC M, PAL N2, PAL B/D/G/H/I, PAL-M3, and PAL 60 standards with a single 27 MHz clock requirement. It includes Macrovision 7.1 copy protection, CGMS, and WSS signaling capabilities. Power consumption is optimized through advanced management circuits supporting normal, low power, and sleep modes.

Feature Summary

• Converts digital YCrCb data to analog composite, S-video, or component outputs
• Integrates SSAF™ technology for extended luminance frequency response
• Supports programmable luma and chroma filters for various resolutions
• Includes on-chip timing generator and real-time control synchronization

Applications

• Portable video applications
• Mobile phones
• Digital still cameras

Procurement Notes

Verify the specific suffix 'WB' against official Analog Devices documentation to confirm automotive qualification status and temperature range specifications. Ensure the ordering information matches the exact package type and revision level required for the design. Cross-reference the datasheet revision history for any updates to electrical characteristics or pin functions before finalizing procurement.

Selection Notes

Select this component when designing systems requiring conversion of digital video streams to analog TV signals in compact form factors. Consider the 40-lead LFCSP package size for space-constrained mobile devices. Evaluate power requirements against the available supply voltage options of 2.8 V or 3.3 V. Verify compatibility with the host processor's I2C interface for register configuration and control.

Part Context

This part belongs to the ADV7174/ADV7179 family of video encoders manufactured by Analog Devices. The ADV7174 variant specifically includes Macrovision 7.1 support, whereas the ADV7179 does not. Both share identical core functionality regarding video encoding, filtering, and output generation within the same small footprint package.

Replacement Considerations

The ADV7179 serves as a functional alternative if Macrovision copy protection is not required. Check for newer generations in the ADV7xxx series for updated performance metrics or additional features.
