HSP43220VC-25

Overview

The HSP43220VC-25 is a monolithic, high-performance decimating digital filter manufactured by Harris Corporation. It integrates a 16-bit analog-to-digital converter, a programmable finite impulse response (FIR) filter, and a 24-bit digital-to-analog converter on a single chip. The device operates with a maximum clock frequency of 25.64 MHz and requires a single 5 V power supply. It features an external 16-bit data bus for input and a 24-bit output data bus. The component is housed in a ceramic metal-sealed cofired PGA84 package with 84 terminals. It supports low-power modes and functions within an operating temperature range of -40 °C to +85 °C.

Feature Summary

• Integrates a 16-bit ADC, programmable FIR filter, and 24-bit DAC for complete signal processing
• Provides linear phase narrowband filtering capabilities with decimation functionality
• Utilizes a ceramic CPGA84 package suitable for robust industrial environments

Applications

• Digital down-conversion in communication systems
• Narrowband filtering applications requiring linear phase response
• High-resolution signal processing modules

Procurement Notes

Verify the manufacturer status as Harris Corporation has undergone corporate changes, with assets often associated with Renesas or Intersil. Confirm the specific suffix 'VC' denotes the commercial temperature grade (-40°C to +85°C) and ceramic package variant. Check for RoHS compliance status, as original Harris components may not meet current environmental standards. Ensure availability through authorized distributors or surplus channels due to potential discontinuation.

Selection Notes

Select this component when a combined ADC-filter-DAC solution is required to reduce system complexity. The 25 MHz clock speed defines the maximum input bandwidth. Ensure the design accommodates the 16-bit input and 24-bit output data widths. Verify that the PGA84 footprint matches the PCB layout. Consider thermal management for the ceramic package if operating near the upper temperature limit.

Part Context

The HSP43220 series belongs to Harris Corporation's family of high-speed digital filters. These devices were designed to replace discrete filter implementations in RF and IF stages. The 'HSP' prefix typically denotes Harris Signal Processing products. This specific model represents a decimating filter architecture, commonly used in software-defined radio and telemetry receivers before the prevalence of highly integrated SoCs.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Equivalent solutions may require discrete FPGA-based filter designs or modern integrated DSPs from manufacturers such as Analog Devices or Texas Instruments. Verify pin compatibility and register interfaces if considering alternative architectures.
