HSP43168JC-45

Overview

The HSP43168JC-45 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 from 1 to 16 and includes on-board storage for 32 sets of coefficients. It processes 10-bit data and coefficients, enabling complex filtering, quadrature operations, and 2-D convolution. The component operates within a commercial temperature range of 0°C to +70°C and utilizes a standard microprocessor interface.

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
• Supports programmable decimation up to 16x with programmable output rounding
• Standard microprocessor interface for configuration and control

Applications

• Quadrature and complex signal filtering
• Image processing and polyphase filtering
• Adaptive filtering systems

Procurement Notes

Verify manufacturer authenticity as Harris Corporation was acquired by Intersil, which later became part of Renesas Electronics. Confirm the specific suffix 'JC' denotes the commercial temperature grade and package variant. Check current availability status as this component may be discontinued or superseded by newer generations in the HSP43168 family.

Selection Notes

Select this component when dual independent FIR filtering or combined 16-tap processing is required. Ensure the design accommodates the 10-bit data width and 16x maximum decimation ratio. Verify that the standard microprocessor interface matches the system's control bus requirements and that the commercial temperature range meets environmental specifications.

Part Context

The HSP43168JC-45 belongs to the HSP43168 family of high-speed digital filters originally developed by Harris Semiconductor. This series was widely used in communications and radar applications requiring flexible digital signal processing capabilities. The 'JC' suffix typically indicates the commercial operating temperature range and specific package type, distinguishing it from military or extended temperature variants.

Replacement Considerations

Direct replacements include the HSP43168VC-45Z and other HSP43168 variants from Renesas/Intersil. Verify pin compatibility and software register mapping before substitution. Newer integrated DSP solutions may offer higher tap counts but require architectural redesign.
