HSP43220GC-15

Overview

The HSP43220GC-15 is a monolithic digital filter manufactured by Harris Corporation, designed for high-performance signal processing applications. It integrates a 16-bit MOS architecture within a CPGA84 package, featuring an external data bus width of 16 bits and an output data bus width of 24 bits. The device operates on a single 5 V power supply and supports a maximum clock frequency of 15 MHz, corresponding to its speed grade suffix. It functions as a decimating digital filter with linear phase characteristics, suitable for narrowband applications requiring precise signal filtering capabilities.

Feature Summary

• Integrates a 16-bit MOS digital filter architecture for high-resolution signal processing
• Provides linear phase response suitable for narrowband signal applications
• Features decimation functionality to reduce sampling rates while maintaining signal integrity

Applications

• Narrowband signal filtering in communication systems
• Decimation filtering in digital receiver architectures
• Signal processing in embedded control environments

Procurement Notes

Verify the manufacturer origin carefully, as the HSP43220 series was originally developed by Harris Semiconductor, which was subsequently acquired by Intersil and later Renesas Electronics. Ensure that the specific GC-15 suffix corresponds to the required 15 MHz speed grade and ceramic PGA84 package configuration when sourcing replacements or verifying component authenticity against original datasheets.

Selection Notes

Select this component when a fixed-function 16-bit digital filter with decimation capability is required. The choice depends on the need for a dedicated hardware solution rather than programmable logic, specifically for applications demanding linear phase response at clock frequencies up to 15 MHz. Verify compatibility with the 5 V supply voltage and the CPGA84 footprint during PCB design.

Part Context

The HSP43220 series represents a family of monolithic digital filters from Harris Semiconductor. These devices combine analog-to-digital conversion concepts with digital filtering techniques on a single chip. The HSP43220GC-15 is part of this lineage, offering a specialized solution for decimating filtered outputs in high-speed data acquisition and communication front-ends.

Replacement Considerations

Check for equivalents from Renesas Electronics or Intersil, as they inherited the product line. Verify pinout and electrical specifications match exactly, particularly the 15 MHz clock limit and 5 V operation.
