ADV7176AKS

Overview

The ADV7176AKS is a high-quality, 10-bit digital video encoder manufactured by Analog Devices Inc. It converts Digital CCIR-601 4:2:2 YCrCb component video data into standard analog baseband television signals for NTSC and PAL standards. The device features integral nonlinearity of less than 1 LSB at 10 bits and supports an 80 dB video signal-to-noise ratio. It operates with a single 27 MHz clock or alternative frequencies for square pixel operation. The encoder provides multiple output formats including composite (CVBS), S-Video (Y/C), YUV, and RGB via four 10-bit DACs. It accepts 8-bit or 16-bit parallel input data through a CCIR-656 compatible pixel port and includes a complete on-chip video timing generator.

Feature Summary

• Converts digital 4:2:2 YCrCb component video to analog NTSC/PAL baseband signals
• Supports simultaneous multi-standard video outputs including composite, S-Video, YUV, and RGB
• Integrates a 32-bit direct digital synthesizer for precise color subcarrier generation
• Includes a complete on-chip video timing generator with programmable master/slave modes

Applications

• MPEG-1 and MPEG-2 video systems
• Digital satellite and cable set-top boxes
• PC video and multimedia applications

Procurement Notes

Verify the specific suffix 'KS' corresponds to the 44-lead MQFP package and 0°C to 70°C temperature range as listed in the ordering guide. Confirm that the required revision level matches the current datasheet version to ensure compatibility with pin definitions and electrical specifications.

Selection Notes

Select this model when Macrovision anticopy protection is not required, as the ADV7175A variant provides this feature. Ensure the system design accommodates the 44-lead thermally enhanced MQFP package dimensions. Verify that the host processor can supply the necessary 27 MHz clock and interface with the 8-bit or 16-bit parallel pixel data ports.

Part Context

This component belongs to the ADV7175A/ADV7176A family of digital video encoders. The ADV7176A is functionally identical to the ADV7175A but lacks the integrated Macrovision antitaping Rev 7.01 algorithm. Both devices share the same pinout, thermal performance characteristics, and core video processing capabilities within the same product line.

Replacement Considerations

The ADV7175AKS is a functional substitute if Macrovision support is needed. Other members of the ADV717x series may offer different resolutions or interfaces but require verification of pin compatibility and register maps.
