MAX7432EUD-T

Overview

The MAX7432EUD-T is a standard definition video reconstruction filter and buffer manufactured by Analog Devices Inc. under the Maxim Integrated brand. It serves as a high-performance replacement for discrete filter solutions, designed to reconstruct analog video from digital data streams. The device operates on a single +5V supply and features a 6th-order lowpass filter with a cutoff frequency optimized for NTSC, PAL, and SDTV signals. It includes a single-pin bus interface for digital control of channel selection, high-frequency boost, bypassing, and output disable functions.

Feature Summary

• Integrates a 6th-order lowpass filter and buffer for CVBS, Y/C, and RGB outputs
• Features a single-pin bus interface for digital configuration of gain and mode
• Includes an input multiplexer and programmable high-frequency boost levels

Applications

• Set-top boxes
• DVD players
• Hard-disk recorders
• Camcorders

Procurement Notes

Verify the specific suffix 'T' against the official datasheet to confirm tape-and-reel packaging status. Confirm RoHS compliance details directly from the manufacturer's documentation. Ensure the component matches the exact MAX7432A variant specifications before integration into production designs.

Selection Notes

Select this component for applications requiring reconstruction of NTSC, PAL, or SDTV video signals from digital sources. It is suitable where space constraints favor an integrated solution over discrete components. Verify that the single +5V supply requirement aligns with the system power architecture.

Part Context

This part belongs to the MAX7428/MAX7430/MAX7432A family of video reconstruction filters. While the MAX7428 is a single-channel device and the MAX7430 is dual-channel, the MAX7432 provides the necessary filtering for standard definition video buffers in a TSSOP package.

Replacement Considerations

The MAX7428 and MAX7430 are related parts within the same family but differ in channel count and pinout. Direct substitution requires verifying pin compatibility and ensuring the application does not require the specific channel configuration of the alternative.
