HSP43220JC-33

Overview

The HSP43220JC-33 is a high-performance analog-to-digital converter (ADC) from the Intersil HSP43220 series, designed for demanding signal processing applications. It features a sampling rate of 40 MSPS and an input bandwidth exceeding 150 MHz. The device integrates a sample-and-hold amplifier, a precision reference, and a digital decimation filter to provide high dynamic range performance. It operates on a single +5V supply and utilizes a PLCC-84 surface-mount package. Key electrical specifications include a typical spurious-free dynamic range (SFDR) of 70 dBc at 10 MHz input and a noise figure of approximately 68 dB. The component supports both binary and offset binary output codes.

Feature Summary

• Integrates a high-speed sample-and-hold amplifier with a built-in digital decimation filter for enhanced signal purity.
• Provides high dynamic range performance suitable for wideband communication systems.
• Features a compact PLCC-84 surface-mount package for efficient board space utilization.
• Operates from a single +5V power supply, simplifying system power design.

Applications

• Wideband communication receivers
• Digital radio frequency memory (DRFM) systems
• Test and measurement equipment
• Software-defined radio (SDR) front ends

Procurement Notes

Verify authenticity through authorized distributors or direct manufacturer channels due to potential availability issues. Confirm the specific suffix indicates the correct speed grade and package variant. Check for RoHS compliance status if required by current manufacturing standards. Ensure proper handling procedures are followed during procurement and storage to maintain component integrity.

Selection Notes

Select this model when a 40 MSPS sampling rate and >150 MHz analog bandwidth are required. Compare against the -25Z variant if a lower speed grade suffices for the application. Consider the PLCC-84 package constraints for PCB layout. Evaluate power consumption requirements against other ADCs in the same family if thermal management is critical.

Part Context

This component belongs to the HSP43220 family of high-speed ADCs from Intersil, now part of Renesas Electronics. The family is known for combining analog front-end capabilities with digital filtering to reduce system complexity. These devices were widely used in professional video and communications before being succeeded by newer generations.

Replacement Considerations

Check for official cross-reference documents from Renesas/Intersil. Potential substitutes may include newer members of the HSP4xxx series or compatible high-speed ADCs from other manufacturers, provided pinouts and electrical specs align. Verify that any replacement maintains the required 40 MSPS rate and SFDR performance.
