ADV7177KSZ-REEL

Overview

The ADV7177KSZ-REEL is an integrated digital video encoder manufactured by Analog Devices Inc. It converts digital CCIR-601 4:2:2 YCrCb component video data into standard analog baseband television signals compatible with NTSC and PAL standards. The device features three high-quality 9-bit video DACs, a 32-bit direct digital synthesizer for color subcarrier generation, and programmable luma/chroma filters. It supports single-supply operation at 5 V or 3.3 V, operates within a commercial temperature range of 0°C to +70°C, and utilizes a 44-lead MQFP package.

Feature Summary

• Converts digital CCIR-601 4:2:2 component video data into analog composite, S-video, YUV, or RGB outputs.
• Includes on-chip voltage reference, timing generator, and OSD support for the ADV7177 variant.
• Features programmable multimode master/slave operation and I2C-compatible serial interface.
• Supports full video-level drive capability or low signal drive mode via external buffering.

Applications

• MPEG-1 and MPEG-2 video systems
• Digital satellite and cable set-top boxes
• Digital televisions and PC multimedia

Procurement Notes

Verify the specific suffix 'KSZ' against official documentation to confirm package type and operating temperature range. Confirm that the '-REEL' designation matches the required tape-and-reel packaging quantity. Ensure the source document explicitly lists this exact part number as available or discontinued before procurement planning.

Selection Notes

Select the ADV7177 if On-Screen Display (OSD) functionality is required. Choose the ADV7178 if Macrovision AntiTaping support is needed instead. Verify power supply requirements match the 5 V or 3.3 V specifications in the datasheet. Ensure the application requires 9-bit DAC resolution and 27 MHz clock input compatibility.

Part Context

This component belongs to the ADV7177/ADV7178 family of integrated digital video encoders. These devices are designed to replace older discrete encoding solutions by integrating multiple functions into a single chip. The family supports various video standards including NTSC-M and PAL-B/D/G/H/I/N/M.

Replacement Considerations

The ADV7170 and ADV7171 are functionally similar encoders from the same manufacturer but feature 10-bit DACs and different filter characteristics. Verify pinout compatibility and register programming differences when considering these alternatives.
