HSP43168JC-45S5001

Overview

The HSP43168JC-45S5001 is a dual finite impulse response (FIR) filter manufactured by Harris Corporation, part of the HSP43168 series. It integrates two independent 8-tap FIR filters that can be configured as a single 16-tap unit. The device supports programmable decimation ratios up to 16 and includes on-board storage for 32 sets of coefficients. It processes 10-bit data and coefficients via a standard microprocessor interface. The component operates within a commercial temperature range of 0°C to +70°C and is housed in a 100-pin plastic quad flat package (PQFP).

Feature Summary

• Dual independent 8-tap FIR filter architecture configurable as a single 16-tap filter.
• On-board storage capacity for 32 programmable coefficient sets.
• Programmable decimation functionality supporting ratios from 1 to 16.
• Standard microprocessor interface for control and data transfer.

Applications

• Quadrature and complex filtering applications.
• Image processing systems requiring convolution or correlation.
• Polyphase filtering structures.
• Adaptive filtering implementations.

Procurement Notes

Verify the specific suffix S5001 against official manufacturer documentation to confirm pinout and electrical characteristics. Confirm end-of-life status with the supplier prior to procurement. Ensure compatibility with existing board layouts and thermal management requirements for the PQFP package.

Selection Notes

Select this component when dual-channel FIR processing or high-speed decimation is required. Verify that the 10-bit resolution meets system accuracy needs. Ensure the host processor supports the required interface protocol. Check availability due to potential obsolescence of older Harris/Intersil components.

Part Context

This component belongs to the HSP43168 family of dual FIR filters produced by Harris Corporation and later Intersil/Renesas. The 'JC' designation typically indicates commercial temperature range and lead-free packaging. The '45' suffix denotes the clock speed capability. This series was widely used in telecommunications and signal processing hardware before being phased out.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided source material. Consult current Renesas or Intersil catalogs for modern replacements. Verify functional equivalence regarding tap count, decimation capabilities, and interface compatibility before substitution.
