MAX11509UUD+T

Video Processing Overview

The MAX11509UUD+T is a three-channel video filter IC in a 14-pin TSSOP package. It provides selectable -3dB bandwidths of 10MHz (SD), 17MHz (PS), 34MHz (HD), and 60MHz (BP). The device features +6dB gain output buffers driving a 150Ω load with a 2Vp-p signal. It operates from a single +5V supply within the 0°C to +85°C temperature range.

Video Processing Feature Summary

• Integrated transparent input clamps for AC- or DC-coupled signals
• +0.8dB peaking passband response to compensate for DAC rolloff
• Selectable bias circuitry for bipolar video signal connections
• Shutdown mode reduces current consumption to 1µA

Video Processing Applications

• Cable and Satellite STB Receivers
• HDTV
• DVD Players
• Personal Video Recorders
• DVRs

Video Processing Procurement Notes

Verify the specific suffix against official documentation, as ordering codes may indicate variations in packaging or environmental compliance. Confirm lead times and availability directly with authorized distributors or the manufacturer. Ensure the component meets RoHS standards if required by your design specifications.

Video Processing Selection Notes

Select this part when system performance requires compensation for DAC rolloff via its specific +0.8dB peaking characteristic. It is suitable for designs needing integrated filtering and buffering without external coupling capacitors. Verify that the 14-pin TSSOP footprint aligns with your PCB layout constraints.

Video Processing Part Context

This component belongs to the Maxim Integrated MAX11508/MAX11509 family of low-cost, multi-standard video filters. While functionally similar to the MAX11508, it is distinguished by its frequency response profile designed to counteract system rolloff effects.

Video Processing FAQ

How does the MAX11509 differ from the MAX11508?

The MAX11509 includes a +0.8dB peaking passband response in SD, PS, and HD modes to compensate for DAC rolloff, whereas the MAX11508 maintains a flat passband.

What is the purpose of the BIAS control input?

The BIAS input enables voltage bias on two channels, allowing simple connection to bipolar video signals like C, Pb, and Pr when forced low.
