HSP43220VC-33

Overview

The HSP43220VC-33 is a high-performance digital filter component manufactured by Harris Corporation. It features a 16-bit architecture and utilizes MOS technology within a CPGA84 package. The device operates with a maximum clock frequency of 33 MHz, supporting an external data bus width of 16 bits and an output data bus width of 24 bits. It functions as a decimating digital filter designed for narrowband signal processing applications.

Feature Summary

• Implements linear phase characteristics suitable for precise signal filtering
• Integrates decimation capabilities to reduce sampling rates while maintaining signal integrity
• Utilizes ceramic metal-sealed cofired packaging for robust environmental stability

Applications

• Narrowband signal processing in communication systems
• Digital down-conversion stages in software-defined radio architectures
• High-speed data acquisition systems requiring precise frequency selection

Procurement Notes

Verify the specific suffix 'VC-33' against official Harris or Intersil documentation to confirm voltage and temperature ratings. Ensure compatibility with existing system power supplies and clock frequencies. Check for RoHS compliance status as original manufacturing records may indicate non-compliance with modern standards. Confirm package pinout alignment before integration.

Selection Notes

Select this component when a dedicated hardware solution for 16-bit decimation filtering is required at speeds up to 33 MHz. Consider the CPGA84 package constraints for PCB layout and thermal management. Evaluate if the fixed 24-bit output width meets downstream processing requirements without additional buffering.

Part Context

This part belongs to the HSP43220 series of digital filters, originally developed by Harris Semiconductor, which was later acquired by Intersil and subsequently Renesas Electronics. The series is characterized by its ability to perform complex digital filtering operations in analog front-end applications, bridging the gap between analog signals and digital processors.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in standard distributor catalogs. Legacy equivalents may require adapter boards due to package differences. Verify functional compatibility regarding clock speed and bus widths if considering alternative decimating filters from other manufacturers.
