HSP50016JI-52

Overview

The HSP50016JI-52 is a single-chip Digital Down Converter (DDC) manufactured by Intersil. It integrates a synthesizer, quadrature mixer, and lowpass filter to perform down conversion, narrowband filtering, and decimation on sampled data streams up to 16 bits wide at rates of 75 MSPS. The device supports CW, frequency hopped, and linear FM signal formats. Internal processing includes a High Decimation Filter and fixed FIR filter with stopband attenuation exceeding 106dB. Output data can be configured in fixed point or single precision floating point formats.

Feature Summary

• Integrates digital synthesizer, quadrature mixer, and dual-channel lowpass filtering for baseband signal generation
• Supports complex modulation formats including CW, frequency hopping, and linear chirp signals
• Provides high-performance filtering with combined High Decimation and FIR stages for superior shape factor
• Offers flexible serial control interface compatible with standard microprocessor I/O ports

Applications

• Software Defined Radio (SDR) receiver front ends
• Digital communication system demodulation
• Signal processing for radar and electronic warfare systems
• Narrowband filtering applications requiring high dynamic range

Procurement Notes

Verify the complete part number including suffixes such as -52, which may indicate specific speed grades or package variants. Confirm RoHS compliance status and lead-free markings on the component marking. Ensure the supplier provides official datasheets from Intersil or Renesas to validate technical specifications against the original design requirements.

Selection Notes

Select this component when a single-chip solution for digital down conversion is required. It is suitable for applications needing high spurious-free dynamic range and precise frequency synthesis. Consider the 75 MSPS input rate limit and 16-bit data width constraints. Evaluate if the integrated filtering meets the necessary stopband attenuation requirements without external components.

Part Context

The HSP50016 series belongs to Intersil's family of high-performance analog and mixed-signal integrated circuits. These devices are designed for advanced signal processing tasks in communications and defense electronics. The HSP50016 specifically addresses the need for compact, high-speed digital down conversion solutions in modern receiver architectures.

Replacement Considerations

Public confirmed substitute part numbers include HSP50016GC-52 and HSP50016JC-52. Verify pinout compatibility and electrical parameter equivalence before substitution. Check for any differences in packaging or thermal characteristics that may impact board layout.
