HSP43168JC-33Z

Overview

The HSP43168JC-33Z is a dual finite impulse response (FIR) filter manufactured by Renesas Electronics Corporation. It integrates two independent 8-tap FIR filters that can be configured as a single 16-tap filter. The device supports programmable decimation from 1 to 16 and provides on-board storage for 32 sets of coefficients. It processes 10-bit data and coefficients, supporting up to 256 FIR taps or 16x16 2-D kernels. The component operates within a temperature range of 0°C to +70°C and utilizes an 84-lead PLCC package.

Feature Summary

• Dual architecture with two independent 8-tap FIR cells configurable as a single 16-tap filter
• On-board storage for 32 user-programmable coefficient sets allowing asynchronous switching
• Programmable decimation factors up to 16 to extend effective filter tap counts
• Standard microprocessor interface for configuration and control

Applications

• Quadrature and complex filtering
• Image processing
• Polyphase filtering
• Adaptive filtering

Procurement Notes

Verify the specific ordering suffix Z indicates Pb-free packaging compliant with RoHS standards. Confirm the JC-33 designation corresponds to the 84-lead PLCC package variant. Check current availability status as this component may be discontinued or not recommended for new designs. Ensure compatibility with existing system voltage requirements before procurement.

Selection Notes

Select this component when dual independent filtering or extended single-filter capabilities are required. Verify that the 10-bit data width meets application precision needs. Ensure the host processor can interface with the standard microprocessor bus. Consider the 84-lead PLCC package constraints for PCB layout. Evaluate if the commercial temperature range suits the operational environment.

Part Context

This part belongs to the HSP43168 series of dual FIR filters originally developed by Intersil Corporation and later acquired by Renesas Electronics. The series is designed for high-performance digital signal processing applications requiring flexible filter configurations. The JC-33 variant specifically denotes the plastic leaded chip carrier package option within this product line.

Replacement Considerations

The datasheet explicitly states 'NO RECOMMENDED REPLACEMENT'. Engineers should verify pinout and functional compatibility if considering alternative dual FIR filters. Contact technical support for potential obsolescence management strategies.
