MAX11508UUD+

Video Processing Overview

The MAX11508UUD+ is a low-cost, three-channel video filter with an integrated output buffer. It supports HD, progressive-scan (PS), SD, and bypass modes. The device operates from a single +5V supply within the commercial temperature range of 0°C to +85°C. It features selectable -3dB bandwidths: 9MHz for SD, 16MHz for PS, 33MHz for HD, and 60MHz for bypass. The output buffers provide +6dB gain, driving a standard 150Ω load with a full 2VP-P signal. Inputs support transparent clamping for AC or DC coupling.

Video Processing Feature Summary

• Three channels of integrated 6th-order lowpass filters with selectable frequency bands
• Integrated output buffers providing +6dB gain for direct drive of standard video loads
• Transparent input clamps enabling flexible AC- or DC-coupled signal connections
• Low-power shutdown mode reducing typical current consumption to 1µA

Video Processing Applications

• Cable and Satellite Set-Top Box Receivers
• High-Definition Television Systems
• Digital Video Disc Players
• Personal Video Recorders and DVRs

Video Processing Procurement Notes

Verify the component matches the specific MAX11508 variant rather than the MAX11509, as they differ in passband response characteristics. Confirm the package type is the 14-pin TSSOP and that the suffix indicates lead-free compliance. Ensure the operating environment falls within the specified commercial temperature range of 0°C to +85°C before finalizing procurement.

Video Processing Selection Notes

Select the MAX11508UUD+ when a flat passband response is required for video filtering applications. This variant differs from the MAX11509 by lacking high-frequency peaking, making it suitable for systems where system rolloff compensation is unnecessary. Verify that the single +5V supply voltage aligns with the target design constraints and that the 14-pin TSSOP footprint fits the PCB layout requirements.

Video Processing Part Context

This component belongs to the Maxim Integrated MAX11508/MAX11509 family of low-cost video filters. These devices are designed to process analog video signals for various display and recording equipment. The series integrates multiple filter stages and output drivers into a compact surface-mount package, simplifying the design of multi-channel video processing circuits.

Video Processing Replacement Considerations

The MAX11509UUD+ serves as a functional substitute within the same family. While electrically similar regarding power and pinout, the MAX11509 includes +0.8dB peaking in its passband response to compensate for DAC rolloff, unlike the flat response of the MAX11508.
