LM98722CCMT

Analog Front End (AFE) Overview

The LM98722CCMT is a three-channel analog front-end (AFE) integrated circuit manufactured by Texas Instruments. It features three independent 16-bit analog-to-digital converters (ADCs) operating at a sampling rate of up to 45 MSPS. The device integrates a CCD/CIS sensor timing generator and spread spectrum clock generation capabilities. It supports both LVDS and CMOS output interfaces for high-speed data transmission. The component is designed for applications requiring precise image signal acquisition and processing.

Analog Front End (AFE) Feature Summary

• Three-channel architecture with 16-bit resolution and 45 MSPS sampling rate per channel
• Integrated CCD/CIS sensor timing generator for synchronized control
• Spread spectrum clock generation to reduce electromagnetic interference (EMI)
• Dual output interface options supporting both LVDS and CMOS standards

Analog Front End (AFE) Applications

• Medical imaging systems utilizing CCD or CIS sensors
• Industrial machine vision equipment
• Scientific instrumentation requiring multi-channel data acquisition

Analog Front End (AFE) Part Context

The LM98722CCMT belongs to the LM98722 family of analog front-ends from Texas Instruments, originally developed under National Semiconductor. This specific package variant (CCMT) denotes a TSSOP form factor. The device serves as a bridge between optical sensors and digital processing units, consolidating ADC and timing functions into a single chip to simplify system design.

Analog Front End (AFE) Replacement Considerations

The LM98722CCMT/NOPB is the lead-free version of this component. Designers should verify pin compatibility and electrical specifications when substituting between these variants. No other direct cross-model replacements are documented in public sources.
