ADV7162KS140

Overview

The ADV7162KS140 is a 96-bit pixel port Video RAM-DAC featuring triple 10-bit gamma-corrected DACs. It supports screen resolutions up to 1600 × 1280 at 85 Hz refresh rates. The device operates with a maximum clock frequency of 140 MHz and includes an on-board PLL, 64 × 64 hardware cursor generator, and color palette RAM. It utilizes a +5 V power supply and accepts TTL-compatible digital inputs while providing RS-343A/RS-170 compatible RGB analog outputs.

Feature Summary

• Integrates triple 10-bit DACs with gamma correction for true-color video generation
• Includes programmable pixel port supporting multiple data formats via multiplexing
• Features on-board user-definable cursor generator and color palette RAM
• Provides fully programmable on-board 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 '140' corresponds to the required 140 MHz operational frequency. Confirm package compatibility with the 160-lead Plastic Quad Flatpack (QFP) footprint. Ensure design accounts for the specified 0°C to +70°C operating temperature range and +5 V power requirements.

Selection Notes

Select this component when a 140 MHz pixel clock rate is sufficient for the target display resolution. Compare against the ADV7160 variant if thermal management capabilities are critical, as the ADV7162 uses a standard QFP package without an embedded heatsink. Verify that the system architecture supports the required 96-bit parallel pixel input interface.

Part Context

This part belongs to the ADV7160/ADV7162 family of high-performance Video RAM-DACs manufactured by Analog Devices. The series is designed for graphics subsystems in workstations and accelerators. The ADV7162 differs from the ADV7160 primarily in its packaging, utilizing a standard 160-lead QFP instead of a thermally enhanced version.

Replacement Considerations
