HSP43220JC-25

Overview

The HSP43220JC-25 is a high-performance active filter with an integrated anneal decimating digital filter, manufactured by Intersil (now Renesas). It operates at a clock frequency of 25 MHz and features a 16-bit data path. The device is housed in an 84-pin PLCC package and is designed for applications requiring precise signal processing. It supports a supply voltage of 5V and functions within a commercial temperature range of 0°C to +70°C.

Feature Summary

• Integrates analog filtering with digital decimation capabilities
• Supports 16-bit data processing architecture
• Operates with a 25 MHz clock input

Applications

• Digital signal processing systems
• Communication equipment requiring band-limiting
• Test and measurement instrumentation

Procurement Notes

This component is listed as obsolete or end-of-life by the manufacturer. Sourcing requires verification of authenticity from authorized distributors or surplus dealers. Buyers should confirm the specific suffix 'Z' indicates RoHS compliance status and verify the manufacturing date code to ensure component integrity before integration into new designs.

Selection Notes

Engineers selecting this part must account for its discontinued status and limited availability. Design reviews should assess whether newer generations of mixed-signal filters from Renesas offer pin-compatible or functionally equivalent alternatives. Verification of the 84-pin PLCC footprint compatibility is essential for existing PCB layouts.

Part Context

The HSP43220 series represents a family of high-speed analog-to-digital interface components developed by Harris Semiconductor and later acquired by Intersil. These devices were prominent in the 1990s for video and RF applications. The JC-25 variant specifically denotes the commercial temperature grade and 25 MHz speed bin within this legacy product line.

Replacement Considerations

No direct public substitute part numbers are confirmed for this obsolete model. Engineers should consult Renesas current portfolios for modern sigma-delta converters or programmable gain amplifiers that meet similar bandwidth and resolution requirements.
