ADV7173KST-REEL

Overview

The ADV7173KST-REEL is a digital PAL/NTSC video encoder manufactured by Analog Devices Inc. It converts digital CCIR-601 4:2:2 YCrCb data into analog baseband television signals using six 10-bit DACs. The device supports multiple output formats including composite, S-Video, and YUV. It operates on a single 5 V or 3.3 V supply with normal mode currents of up to 90 mA at 5 V and 40 mA at 3.3 V. Sleep mode current is 0.1 µA. The component features an I²C interface, accepts a 27 MHz clock, and functions within a temperature range of 0°C to +70°C in a 48-lead LQFP package.

Feature Summary

• Integrates Super Sub-Alias Filter (SSAF) for high-resolution luminance response
• Supports PC'98-compliant auto-detect and shutdown for power optimization
• Includes programmable color controls for hue, brightness, contrast, and saturation
• Generates CGMS and WSS signaling data internally

Applications

• High performance DVD playback systems
• Portable video equipment such as digital still cameras and laptop PCs
• Digital satellite and cable set-top boxes

Procurement Notes

Verify the specific reel packaging configuration against the manufacturer's latest documentation before procurement. Confirm that the KST suffix corresponds to the required 48-lead LQFP plastic thin quad flatpack variant. Ensure compatibility with the intended operating voltage and temperature range specifications.

Selection Notes

Select this model when a complete digital-to-analog conversion solution is required for standard definition video. The ADV7173 lacks Macrovision anti-copy capabilities found in the ADV7172; verify if copy protection is necessary for the application. Consider the available DAC output configurations and current drive requirements when designing the external load circuitry.

Part Context

This component belongs to the ADV7172/ADV7173 family of integrated digital video encoders. Functionally identical to the ADV7172 except for the absence of Macrovision support. Designed for converting digital component video data into various analog TV signal standards compatible with global display devices.

Replacement Considerations

The ADV7172KST serves as a functional substitute if Macrovision anti-copy generation is required. Verify pinout and register compatibility between the ADV7173 and ADV7172 variants prior to implementation.
