ADV7171KS

Overview

The ADV7171KS is a digital video encoder that converts CCIR-601 4:2:2 component data into analog baseband signals. It features four 10-bit DACs and operates on a single 5 V or 3.3 V supply. The device supports NTSC M, PAL M/N, PAL B/D/G/H/I, and PAL60 standards with an 80 dB video SNR. Input formats include 8-bit and 16-bit parallel data via a 27 MHz clock. It includes programmable luma/chroma filters, CGMS/WSS insertion, teletext support, and closed captioning. The part is housed in a 44-lead MQFP/TQFP package and functions within an industrial temperature range of −40°C to +85°C.

Feature Summary

• Integrates Super Sub-Alias Filter (SSAF) for high-resolution luminance processing
• Supports simultaneous composite, S-Video, YUV, and RGB EuroSCART outputs
• Includes on-chip color bar generation and voltage reference circuitry
• Features advanced power management with configurable sleep and low-power modes

Applications

• High-performance DVD playback systems
• Portable video equipment including digital still cameras
• Digital satellite and cable set-top boxes
• PC video and multimedia applications

Procurement Notes

Verify the specific suffix 'KS' against the manufacturer's ordering guide to confirm the exact package type and temperature grade. Ensure the design accommodates the required 27 MHz clock input and appropriate RSET resistor values for the target output current configuration.

Selection Notes

Select this component when a dedicated digital-to-analog video encoder is required for standard definition television signals. Consider the ADV7170 if Macrovision AntiTaping Rev 7.1 functionality is necessary, as it is exclusive to that variant. Verify compatibility with the host system's pixel port timing requirements.

Part Context

This device belongs to the ADV7170/ADV7171 family of integrated digital video encoders manufactured by Analog Devices. These components are designed to replace discrete encoding solutions by providing complete signal conversion and filtering capabilities in a single small form factor package suitable for space-constrained consumer electronics.
