LM98722CCMTX/NOPB

Analog Front End (AFE) Overview

The LM98722CCMTX/NOPB is a three-channel analog front-end (AFE) designed for high-speed video applications. It integrates three 16-bit analog-to-digital converters (ADCs) operating at a sampling rate of 45 MSPS. The device features LVDS and CMOS output interfaces to facilitate digital signal transmission. Manufactured by Texas Instruments, this component serves as an image sensor interface solution. The specific package variant is the CCMTX suffix, which denotes a tape and reel packaging format. This AFE is engineered to provide precise digitization for multi-channel video signals.

Analog Front End (AFE) Feature Summary

• Three-channel architecture with integrated 16-bit ADCs
• Maximum sampling rate of 45 MSPS per channel
• Supports both LVDS and CMOS digital output formats
• Designed for direct interfacing with image sensors

Analog Front End (AFE) Applications

• Digital copier systems requiring multi-channel image capture
• High-resolution color scanner interfaces
• Video digitization modules in imaging equipment

Analog Front End (AFE) Procurement Notes

Verify the current lifecycle status before procurement, as availability may be limited due to end-of-life indications. Confirm that the CCMTX suffix matches the required tape and reel quantity specifications for the manufacturing line. Ensure compatibility with existing system voltage levels and clocking requirements specified in the official datasheet prior to ordering.

Analog Front End (AFE) Selection Notes

Select this component when a three-channel, 16-bit resolution is required for simultaneous video signal acquisition. Compare against the LM98714 if a digital copier-specific interface is needed instead of general-purpose AFE functionality. Verify that the 45 MSPS bandwidth meets the Nyquist criteria for the target video frequency spectrum. Check pinout compatibility if replacing legacy National Semiconductor parts.

Analog Front End (AFE) Part Context

This part belongs to the LM9872x family of analog front-ends from Texas Instruments, continuing the lineage of National Semiconductor imaging interfaces. It is functionally related to the LM98714 but offers distinct interface capabilities. The NOPB suffix indicates compliance with RoHS standards and absence of lead-based materials. It is often used in conjunction with serializers like the DS90CR218A for long-distance digital video transmission.

Analog Front End (AFE) Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Designers should consult the manufacturer's obsolescence management page for potential last-time buys or recommended upgrades within the same product family.
