ADV7195KS

Overview

The ADV7195KS is a triple high-speed digital-to-analog encoder manufactured by Analog Devices Inc. It integrates three video D/A converters with TTL-compatible inputs, supporting 10-bit data input in 4:2:2 or 4:4:4 formats. The device operates at 27 MHz for progressive scan and up to 74.25 MHz for HDTV modes. DAC A provides an 11-bit output plus sync, while DAC B and C provide 11-bit outputs. It requires a single 3.3 V supply and features a 52-lead MQFP package.

Feature Summary

• Supports multiformat progressive scan and HDTV encoding standards including SMPTE-293M and ITU-R.BT1358.
• Includes programmable sharpness filter and adaptive filter control for luminance signal enhancement.
• Features an internal test pattern generator with color control capabilities.
• Provides gamma correction and Y/CrCb delay adjustment functions.

Applications

• Progressive Scan/HDTV Display Devices
• Digital Video Systems
• High Resolution Color Graphics

Procurement Notes

Verify the specific suffix KS against official documentation to confirm the commercial temperature range of 0°C to 70°C and the plastic quad flatpack package type. Ensure compatibility with required I2C interface settings and external reference voltage configurations before integration.

Selection Notes

Select this component when designing systems requiring simultaneous conversion of YCrCb or RGB data into analog video signals. Consider the 52-lead MQFP footprint and the need for external decoupling capacitors on the COMP pin and power supplies during layout.
