CDC328ANSR

Specialty Logic Overview

The CDC328ANSR is a low-skew clock driver manufactured by Texas Instruments, designed to distribute one input signal to six outputs. It features selectable polarity for each output, allowing flexible signal inversion control. The device operates within a supply voltage range of 2.3V to 3.6V and supports maximum frequencies up to 400MHz. Packaged in a 16-pin SOIC (NS) format, it utilizes BICMOS technology to ensure minimal skew across all outputs, making it suitable for high-speed clock distribution networks requiring precise timing alignment.

Specialty Logic Feature Summary

• Distributes a single input clock signal to six independent outputs with minimum skew characteristics
• Provides selectable polarity for each output to accommodate varying logic requirements without external components
• Operates over an extended temperature range from -40°C to +85°C for robust industrial performance

Specialty Logic Applications

• High-speed clock distribution in data communication systems
• Timing synchronization in complex digital logic circuits
• Buffering clock signals for memory interfaces and processors

Specialty Logic Procurement Notes

Verify the specific suffix 'ANSR' confirms the active temperature range (-40°C to +85°C), tube packaging, and ANSI-compliant marking. Cross-reference the manufacturer's latest datasheet to confirm current production status and pinout compatibility with existing designs. Ensure the source document explicitly lists this part number as a distinct variant from standard CDC328A or CDC328DR versions.

Specialty Logic Selection Notes

Select this component when a single-source clock requires buffering into six paths with independent polarity control. It is appropriate for designs needing low skew propagation delay and operation within the 2.3V to 3.6V power domain. Consider the 16-pin SOIC package constraints for PCB layout and thermal management relative to higher-density alternatives.

Specialty Logic Part Context

This part belongs to the CDC328 series of clock drivers, which are engineered for low-skew applications. The series includes variants like CDC328A and CDC328DR, differing primarily in packaging, temperature ratings, and manufacturing revisions. The CDC328ANSR specifically denotes the tube-packaged version with extended industrial temperature capabilities.

Specialty Logic Replacement Considerations

Publicly confirmed substitutes include CDC328A and CDC328DR. Verify that alternative packages match the physical footprint and that temperature ranges meet system requirements. Check for any changes in electrical specifications such as skew values or drive strength between these variants.
