ADCS9888CVH-170/NOPB

Overview

The ADCS9888CVH-170/NOPB is a high-performance Analog Front End (AFE) designed for digital video applications. It integrates three independent channels, each featuring an 8-bit resolution analog-to-digital converter. The device supports sampling rates up to 170 MSPS and operates with both digital and analog power supplies at 3.3V. Packaged in a 128-MQFP or 128-PQFP format, it delivers low-noise signal processing capabilities suitable for consumer circuit requirements.

Feature Summary

• Integrates three independent analog front-end channels within a single component
• Provides 8-bit resolution data acquisition for accurate signal processing
• Supports high-speed sampling rates optimized for digital video resolutions

Applications

• Digital video signal processing systems
• Consumer electronic circuits requiring analog front ends
• Low-noise signal acquisition applications

Procurement Notes

Verify the manufacturer designation carefully, as this component was originally developed by National Semiconductor and is now supported under Texas Instruments. Confirm that the specific suffix 'NOPB' indicates lead-free compliance and RoHS adherence. Ensure the package type matches the required 128-pin configuration for your PCB layout. Cross-reference the datasheet version to confirm the 170 MSPS speed grade, as other variants exist.

Selection Notes

Select this component when a multi-channel AFE solution is required for video applications. It is appropriate for designs needing integrated 8-bit conversion without external multiplexing. Consider the 128-pin footprint constraints during layout. Evaluate if the 3.3V supply voltage aligns with the system architecture. This part is suitable for applications prioritizing channel integration over higher bit-depth precision.

Part Context

This component belongs to the ADCS9888 family of video analog front ends. Variants such as the -205 and -140 models offer different sampling rate specifications while maintaining similar architectural features. The series is designed to simplify the design of digital video capture systems by combining multiple functions into a single package. It represents a specialized solution for high-speed video signal conditioning.

Replacement Considerations

Direct substitutes include the ADCS9888CVH-205/NOPB and ADCS9888CVH-140/NOPB. These parts share the same package and pinout but differ in maximum sampling frequency. Verify that the system timing requirements are compatible with the alternative sampling rates before substitution.
