HSP43168VC-40

Overview

The HSP43168VC-40 is a dual finite impulse response (FIR) filter manufactured by Harris Corporation. It integrates two independent 8-tap FIR filters, which can be configured as a single 16-tap unit. The device supports programmable decimation ratios up to 16x and includes on-board storage for 32 sets of coefficients. It utilizes a standard microprocessor interface for control and data transfer. The component operates within a commercial temperature range of 0°C to +70°C and is housed in a 100-pin PQFP package.

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 up to 16
• Standard microprocessor interface for configuration and data access

Applications

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

Procurement Notes

Verify the manufacturer origin carefully, as production rights transferred from Harris to Intersil and subsequently to Renesas. Confirm the specific suffix indicates the -40°C minimum operating temperature variant. Check for RoHS compliance status and lead-free availability, as these attributes vary across different manufacturing eras and distributors. Ensure the package type matches the required PCB footprint.

Selection Notes

Select this component when dual-channel digital filtering with programmable tap counts is required. Consider the 10-bit data width and coefficient precision for signal integrity needs. Evaluate the need for on-board coefficient storage versus external memory constraints. Verify that the standard microprocessor interface compatibility aligns with the host system's bus architecture.

Part Context

The HSP43168 belongs to a family of high-performance digital filters originally developed by Harris Semiconductor. Following corporate acquisitions, the product line was managed by Intersil and later Renesas Electronics. This specific part represents a specialized analog-mixed signal IC designed for high-speed digital signal processing tasks in communication and imaging systems.

Replacement Considerations

Direct replacements may include the HSP43168GM-25/883 or variants from Renesas under the same series. Verify pinout compatibility and electrical specifications before substitution. Cross-reference datasheets to ensure equivalent decimation capabilities and interface standards.
