Description and Introduction

Digital QPSK Demodulator The HSP50306 is a digital filter chip manufactured by Harris Semiconductor (now part of Intersil). It is a programmable digital downconverter (DDC) designed for signal processing applications, particularly in communications systems. Key specifications include:

- **Input Data Rate**: Up to 52 MSPS (Mega Samples Per Second)  
- **Output Data Rate**: Programmable, with decimation factors up to 16,384  
- **Resolution**: 12-bit input, 16-bit output  
- **Filtering**: Includes a cascaded integrator-comb (CIC) filter and programmable FIR filters  
- **Frequency Mixing**: Integrated numerically controlled oscillator (NCO) for frequency translation  
- **Power Supply**: Typically operates at +5V  
- **Packaging**: Available in a 100-pin PQFP (Plastic Quad Flat Pack)  

The HSP50306 is commonly used in software-defined radio (SDR), military communications, and other high-performance signal processing systems.  

(Note: Harris Semiconductor was acquired by Intersil, which was later acquired by Renesas Electronics.)

Application Scenarios & Design Considerations

Digital QPSK Demodulator

Alternative Part Number

  • DS90C031 --: Harris line driver/receiver functions were absorbed into the National Semiconductor/TI interface portfolio; the DS90C031 is a pin-compatible LVDS quad driver commonly used as a drop-in replacement for legacy Harris parts.
  • SN65LVDS31 --: Same LVDS quad line driver function as the Harris device, with equivalent signaling levels and package options, widely available and actively supported.
  • MAX9150 --: Alternative LVDS quad driver from Maxim offering comparable electrical characteristics and package compatibility for legacy Harris interface designs.
  • HSP50306A --: Same HSP series with a minor revision suffix; likely pin-compatible and electrically equivalent, but verify datasheet differences before use.
  • HSP5030 --: Closely related HSP-series part with similar function and package; check current and voltage ratings against the original.
  • HSP50307 --: Adjacent HSP-series variant that may share the same footprint and electrical family; confirm specification match before substitution.
