LM98516CCMTX/NOPB

Analog Front End (AFE) Overview

The LM98516CCMTX/NOPB is a Texas Instruments analog frontend (AFE) designed for video signal processing. It integrates a high-speed analog-to-digital converter and digital copier functions within a single package. The device operates with a 3.3 V supply voltage and features a 10-bit resolution ADC. It supports input frequencies up to 140 MHz, enabling direct digitization of composite and S-video signals without external encoding. The component utilizes a 56-pin Thin Shrink Small Outline Package (TSSOP) with an exposed thermal pad for enhanced heat dissipation.

Analog Front End (AFE) Feature Summary

• Integrated 10-bit, 140 MHz analog-to-digital converter
• Built-in digital copier for signal duplication
• Direct digitization of composite and S-video inputs
• 3.3 V single-supply operation

Analog Front End (AFE) Applications

• Video capture cards and dongles
• Digital video recorders (DVRs)
• Set-top boxes requiring analog video input
• Medical imaging equipment with video interfaces

Analog Front End (AFE) Procurement Notes

Verify the specific suffix 'NOPB' confirms lead-free and RoHS compliance status against the manufacturer's current datasheet revision. Confirm the 'CCM' temperature grade matches application requirements. Check for end-of-life notices or obsolescence warnings from Texas Instruments before finalizing procurement plans.

Analog Front End (AFE) Selection Notes

Select this component when direct digitization of standard definition video signals is required without external encoder chips. Ensure the PCB layout accommodates the 56-pin TSSOP footprint and provides adequate thermal relief for the exposed pad. Verify that the system clock frequency aligns with the device's maximum sampling rate specifications.

Analog Front End (AFE) Part Context

This part belongs to the LM9851x family of video AFEs. It shares functional similarities with the LM98515 but may differ in pinout compatibility or specific timing parameters. The 'X' suffix indicates reel packaging, while 'NOPB' denotes non-plumbum (lead-free) construction.

Analog Front End (AFE) Replacement Considerations

The LM98515CCMT is a related variant within the same product family. Verify pin-to-pin compatibility and electrical parameter equivalence before substitution. Consult the official Texas Instruments comparison guide for detailed differences between these specific model numbers.
