• Integrates triple 10-bit true-color DACs with gamma correction capabilities
• Includes programmable 96-bit pixel port supporting multiple data formats
• Features onboard color palette RAM and user-definable hardware cursor
• Provides fully programmable on-board PLL for clock generation

Applications

• Windows Accelerators
• High Resolution True Color Graphics
• Professional Color Prepress Imaging
• Digital TV (HDTV, Digital Video)

Procurement Notes

Verify the specific speed grade suffix matches the required clock frequency. Confirm package type corresponds to the thermal enhancement requirements. Ensure environmental specifications align with the operational temperature range. Check for any specific ordering constraints or documentation updates from the manufacturer before finalizing procurement.

Selection Notes

Select this component for high-performance graphics workstations requiring direct true-color output. Consider the 220 MHz speed grade for maximum resolution and refresh rates. Evaluate the need for onboard palette RAM and cursor generation to simplify system design. Ensure compatibility with RS-343A/RS-170 video standards for analog outputs.

Part Context

This part belongs to the ADV7160/ADV7162 family of Video RAM-DACs manufactured by Analog Devices. The ADV7160 variant features a thermally enhanced QFP package, while the ADV7162 uses a standard plastic QFP. Both share identical functional specifications but differ in packaging and thermal characteristics.

Replacement Considerations

The ADV7160KS170 and ADV7160KS140 are confirmed substitutes within the same family, offering lower clock speeds of 170 MHz and 140 MHz respectively. These parts maintain identical functionality and pinouts but operate at reduced maximum frequencies.
