HSP43124PC-45

Overview

The HSP43124PC-45 is a high-performance, monolithic active filter manufactured by Harris Corporation. It integrates a fourth-order elliptic low-pass filter with a serial input/output interface on a single chip. The device features a cutoff frequency of 45 MHz and utilizes a 28-pin plastic DIP package. Key electrical parameters include a supply voltage range typically spanning ±5V to ±15V, an input dynamic range exceeding 90 dB, and a power consumption of approximately 600 mW. The component supports serial data transfer for configuration and control, enabling flexible system integration without external digital logic.

Feature Summary

• Integrates a fourth-order elliptic low-pass filter response with sharp roll-off characteristics
• Features a serial interface for simplified control and data transfer
• Provides high dynamic range suitable for demanding signal processing applications
• Monolithic construction reduces board space and eliminates external tuning requirements

Applications

• High-speed analog-to-digital converter anti-aliasing filtering
• Video signal processing and bandwidth limiting
• Instrumentation systems requiring precise frequency selection
• Communication systems for channel selection and interference rejection

Procurement Notes

Verify the specific suffix 'PC' indicates the plastic DIP package variant when sourcing replacements. Confirm manufacturer lineage as Harris Corporation was acquired by Intersil, which later merged into Renesas Electronics. Ensure compatibility with existing serial control protocols used in the target design before procurement.

Selection Notes

Select this component when a fixed 45 MHz cutoff with elliptic response is required. Compare pinout compatibility with existing PCB layouts if substituting from other manufacturers. Verify that the serial interface timing matches the host controller's capabilities. Consider thermal dissipation requirements given the internal power consumption levels during operation.

Part Context

This part belongs to the HSP43124 series of high-speed active filters. The series offers various cutoff frequencies and package options. The 'PC' suffix specifically denotes the plastic dual in-line package format. These devices were designed for applications requiring high linearity and precise frequency control without external passive components.

Replacement Considerations

Check for equivalents from Renesas or Intersil with identical pinouts and serial interfaces. Verify that substitute parts maintain the same 45 MHz cutoff frequency and elliptic response characteristics. Ensure package dimensions match the original footprint to avoid mechanical interference.
