ADV7162KSZ140

Overview

The ADV7162KSZ140 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 an 85 Hz refresh rate and operates with clock speeds of 220 MHz, 170 MHz, or 140 MHz. The device includes a fully programmable on-board PLL, a 64 × 64 hardware cursor generator, and three color overlay palette RAM. It utilizes a standard MPU I/O interface and provides RS-343A/RS-170 compatible RGB analog outputs.

Feature Summary

• Integrates triple 10-bit DACs with gamma correction for true-color video generation
• Includes user-definable hardware cursor and multiple color palette RAM banks
• Supports multiplexed pixel input ports for various data formats
• Features an on-board programmable PLL for clock synchronization

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., KSZ140) against the manufacturer's ordering information to confirm the exact clock frequency rating. Ensure the package type matches the required thermal and pin configuration. Confirm RoHS compliance status and operating temperature range requirements prior to procurement.

Selection Notes

Select this component for high-performance graphics workstations requiring direct true-color output. Consider the ADV7160 if a thermally enhanced QFP package is preferred over the standard plastic QFP. Evaluate system timing constraints against the specified pipeline delays and multiplexing rates.

Part Context

This part belongs to the ADV7160/ADV7162 family of video RAM-DACs designed for high-resolution graphics subsystems. The ADV7162 variant specifically utilizes a standard 160-lead plastic quad flatpack (QFP) package, distinguishing it from the thermally enhanced version.
