ADV7162KS220

Overview

The ADV7162KS220 is a 96-bit pixel port Video RAM-DAC featuring triple 10-bit gamma-correcting D/A converters. It supports screen resolutions up to 1600 × 1280 at 85 Hz refresh rates with 24-bit true-color data. The device includes a fully programmable on-board PLL, a 64 × 64 hardware cursor generator, and three 256 × 10 color palette RAMs. It operates at a maximum clock frequency of 220 MHz using +5 V CMOS monolithic construction.

Feature Summary

• Integrates triple 10-bit DACs with 2% maximum color matching for high-fidelity video output.
• Includes user-definable 64 × 64 hardware cursor generation with overlay capabilities.
• Supports multiplexed pixel input ports for various data formats including 24-bit, 16-bit, and 8-bit modes.
• Features RS-343A/RS-170 compatible RGB analog outputs with tri-level sync functionality.

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 (e.g., KS220) against the manufacturer's current ordering information to ensure compatibility with system timing requirements. Confirm package configuration details as the ADV7162 utilizes a standard 160-pin plastic QFP distinct from the thermally enhanced variant. Check for any product change notices regarding assembly relocation or testing transfers that may affect component sourcing.

Selection Notes

Select this component when designing graphics subsystems requiring direct true-color operation without external glue logic. Ensure the design accommodates the 160-lead QFP footprint and provides adequate thermal management if utilizing the power-enhanced variant. Verify that the host processor interface matches the TTL-compatible MPU port specifications for reliable register access and control.

Part Context

This part belongs to the ADV7160/ADV7162 family of video RAM-DACs designed for high-performance workstation graphics. While the ADV7160 features a thermally enhanced package, the ADV7162 uses a standard plastic quad flatpack. Both share identical functional specifications, differing primarily in physical packaging and thermal characteristics for integration into dense circuit boards.
