HSP43168VC-45

Overview

The HSP43168VC-45 is a high-speed, monolithic active filter manufactured by Harris Corporation (now Renesas/Intersil). It integrates dual digital filters within a single package to provide simultaneous low-pass and high-pass filtering capabilities. The device operates with a maximum clock frequency of 45 MHz and supports a wide dynamic range. Designed for commercial temperature ranges from 0°C to +70°C, it utilizes a 100-pin Plastic Quad Flat Package (PQFP) for surface mount installation. This component serves as a versatile solution for complex signal processing tasks requiring precise analog filtering in mixed-signal systems.

Feature Summary

• Dual integrated digital filter architecture enabling simultaneous low-pass and high-pass operations
• High-speed performance supporting clock frequencies up to 45 MHz
• Monolithic design combining multiple filtering functions into a single compact package

Applications

• Wireless communication base station signal processing
• Software-defined radio front-end filtering
• Medical imaging system data acquisition

Procurement Notes

Verify the current lifecycle status before procurement planning, as this component may be classified as obsolete or end-of-life by the manufacturer. Confirm that the 100-pin PQFP footprint matches the target PCB layout requirements. Ensure that the commercial temperature rating of 0°C to +70°C aligns with the operational environment specifications. Validate compatibility with existing clocking and power supply architectures.

Selection Notes

Select this component when a single-chip solution for dual-channel filtering is required to minimize board space and component count. Consider the 45 MHz clock limit when designing for higher bandwidth applications. Evaluate the 100-pin package density against available routing resources on the printed circuit board. Compare power consumption characteristics against alternative discrete filter solutions for efficiency requirements.

Part Context

This part belongs to the HSP43168 series of high-performance active filters developed by Harris Semiconductor. The series was designed to address the growing demand for integrated signal conditioning in telecommunications equipment. The specific suffix indicates the speed grade and package type within the product family.

Replacement Considerations

Check for direct pin-compatible replacements within the HSP43168 series that may offer updated manufacturing availability. Verify if newer generations of active filters from Renesas or Intersil provide equivalent functionality with improved specifications.
