MAX9524ATC+

Video Processing Overview

The MAX9524ATC+ is a standard-definition video filter amplifier featuring an integrated lowpass reconstruction filter and a sync-tip clamp input. It provides a fixed voltage gain of 2V/V with a ±1dB passband flatness up to 9MHz and 52dB attenuation at 27MHz. The device operates from a single 2.7V to 3.6V supply, drawing approximately 4.25mA quiescent current. It includes two SPST analog switches for signal routing and supports both DC-coupled (75Ω) and AC-coupled (150Ω) outputs. The component is specified over the -40°C to +125°C automotive temperature range.

Video Processing Feature Summary

• Integrated sync-tip clamp input designed for external video sources with unknown DC bias levels
• Built-in reconstruction filter optimized for standard-definition composite and luma signals
• Dual single-pole single-throw analog switches for multiplexing audio, video, or digital signals
• Fixed 2V/V gain output stage capable of driving standard video loads

Video Processing Applications

• Security/CCTV Cameras
• Mobile Phones/Cell Phones
• Digital Still Cameras (DSC)
• Camcorders (DVC)
• Portable Media Players (PMP)

Video Processing Procurement Notes

Verify the specific ordering suffix ATC+ corresponds to the AC clamp input variant and lead-free TQFN package. Confirm that the exposed paddle connection requirements are met in the PCB layout design. Ensure the supply voltage remains within the 2.7V to 3.6V operational limits during system testing.

Video Processing Selection Notes

Select this component when the video source requires AC coupling due to undefined DC bias levels. The internal sync-tip clamp eliminates the need for external biasing circuits. Choose this part over the MAX9517 if the application involves external composite video inputs rather than direct DAC connections.

Video Processing Part Context

This device belongs to the MAX9517/MAX9524 family of standard-definition video filter amplifiers manufactured by Maxim Integrated. While sharing identical filter characteristics and switch functionality, the MAX9524 differs from the MAX9517 by incorporating a sync-tip clamp input instead of a DC buffer, making it suitable for external signal interfacing.

Video Processing Replacement Considerations

The MAX9517ATC+ serves as a functional substitute if the application utilizes DC-coupled video sources without unknown bias levels. Both parts share identical pinouts, package dimensions, and electrical performance metrics excluding the input stage configuration.

Video Processing FAQ

How does the MAX9524 handle external video signals with unknown DC bias?

The MAX9524 features an internal sync-tip clamp that automatically sets the correct DC level for incoming composite or luma signals, allowing them to be AC-coupled via a capacitor.

What is the maximum bandwidth of the integrated reconstruction filter?

The filter provides ±1dB passband flatness up to 9MHz, which covers the requirements for standard-definition video formats including NTSC and PAL.
