MAX11507CEE+

Video Processing Overview

The MAX11507CEE+ is a six-channel video filter and buffer integrated circuit designed for standard-definition (SD) and high-definition (HD) video applications. It features three dedicated SD channels with fixed 9MHz bandwidth and three selectable SD/HD channels offering 9MHz or 33MHz bandwidth via the FSEL pin. Each channel includes a transparent input clamp supporting AC- or DC-coupled signals and an output buffer providing +6dB gain to drive 150Ω loads directly. The device operates from a single +5V supply within the commercial temperature range of 0°C to +70°C.

Video Processing Feature Summary

• Six-channel architecture comprising three fixed SD filters and three selectable SD/HD filters
• Integrated +6dB output buffers capable of driving standard 150Ω video loads without external coupling capacitors
• Transparent input clamps enabling compatibility with both AC- and DC-coupled signal sources
• High-frequency boost passband response on SD-only channels to compensate for system roll-off

Video Processing Applications

• Cable and Satellite Set-Top Box Receivers
• Digital Video Recorders (DVRs)
• DVD Players
• Personal Video Recorders (PVRs)

Video Processing Procurement Notes

Verify the component matches the specific MAX11507 variant, which distinguishes itself from the MAX11506 through its high-frequency boost characteristic on SD channels. Confirm the package type is the 16-pin QSOP and that the suffix indicates lead-free construction. Ensure the operating temperature grade aligns with commercial requirements. Cross-reference the datasheet revision to confirm electrical characteristics remain consistent with current manufacturing standards.

Video Processing Selection Notes

Select this component when system design requires compensation for high-frequency attenuation in SD video paths. The MAX11507 is appropriate for mixed SD/HD environments where flexible bandwidth selection is necessary for HD channels. Consider the internal offset voltages and gain settings when designing signal chains. Verify that the single +5V supply constraint fits the power budget. Evaluate PCB layout requirements for bypassing and thermal dissipation in the QSOP package.

Video Processing Part Context

This device belongs to the MAX11506/MAX11507 family of low-cost, multi-channel video filters. While sharing identical hardware structure and pinouts, the MAX11507 differs functionally by incorporating a 0.8dB peaking response on its SD-only channels. This variation addresses specific system-level frequency roll-off issues not present in the flat-response MAX11506. Both parts utilize BiCMOS process technology and serve as anti-aliasing and smoothing filters in digital video processing chains.

Video Processing Replacement Considerations

The MAX11506CEE+ serves as a direct pin-compatible alternative if high-frequency boosting is unnecessary. Verify that the target application does not require the specific 0.8dB peaking characteristic provided by the MAX11507. Ensure any substitute maintains the same 16-pin QSOP footprint and +5V supply operation.
