ADV7177KSZ

Overview

The ADV7177KSZ is a digital video encoder that converts CCIR-601 YCrCb data into analog PAL/NTSC signals. It features three 9-bit DACs with integral nonlinearity of ±1 LSB and supports 5 V or 3.3 V operation. The device accepts 8-bit or 16-bit parallel inputs at 27 MHz, generating composite, S-video, or component outputs. It includes an on-chip voltage reference, OSD support, and closed captioning capabilities within a 44-lead MQFP package.

Feature Summary

• Converts digital CCIR-601 4:2:2 video to analog baseband TV signals
• Includes three 9-bit DACs for high-quality video output
• Supports NTSC-M, PAL-M/N, and PAL-B/D/G/H/I standards
• Features programmable luma filters and color subcarrier synthesis

Applications

• MPEG-1 and MPEG-2 video systems
• Digital satellite and cable set-top boxes
• DVD players and digital TVs
• Video games and PC multimedia devices

Procurement Notes

Verify the specific ordering suffix KSZ against the manufacturer's current datasheet to confirm package type and temperature range. Confirm availability status as discontinued parts may require alternative sourcing strategies.

Selection Notes

Select this model when OSD functionality is required, distinguishing it from the ADV7178 which lacks OSD but includes Macrovision. Ensure the system design accommodates the 44-lead MQFP thermal requirements and provides the necessary 27 MHz clock source.

Part Context

This component belongs to the ADV7177/ADV7178 family of integrated digital video encoders manufactured by Analog Devices. These devices are designed to interface directly with digital video processors, providing a bridge between digital component video formats and standard analog television broadcast signals.

Replacement Considerations

The ADV7178KSZ is a functional substitute lacking OSD support. Verify if Macrovision anticopy features are required; if so, the ADV7178 is preferred. Check for newer generation replacements in the ADV71xx series if long-term supply is a concern.
