Description
The PDSP16515AC0 is an IC Chip that performs Forward or Inverse Fast Fourier Transforms on data sets containing up to 1024 points. This component is completely self-contained and has an internal RAM that can hold up to 1024 complex data points, which removes the memory transfer bottleneck. Its organization allows it to simultaneously input new data, transform data stored in the RAM, and output previous results. Inputs and outputs are synchronous to the 45MHz system clock used for internal operations. The PDSP16515AC0 is designed to be pin and functionally compatible with the PDSP16510A.
Specifications and features
- Data and coefficient input are both represented by 16 bits.
- Data is expanded internally to 18 bits and subject to Block Floating Point arithmetic for increased dynamic range.
- 500 MIP operation gives 87 microsecond transformation times for 1024 points.
- Up to 45MHz sampling rates with multiple devices.
- Up to 85dB noise rejection and a choice of internal window operators with no external ROM provide up to 67dB side lobe attenuation.
- The PDSP16515AC0 is available in either an 84-pin PGA or 132-pin surface mount package.
Application Scenarios
The PDSP16515AC0 is an integral component in Fourier Transform-based applications. It is specifically designed for use in digital signal processing, telecommunications, and audio applications that require a high degree of accuracy and dynamic range to meet today's demanding performance standards.
Comparison
Advantages- Completely self-contained, providing a memory transfer rate that exceeds that of other building block solutions
- Pin and functionally compatible with the PDSP16510A, allowing it to be used in existing circuits
- Expanded width internal RAM supports up to 1024 complex points, providing greater flexibility in the size of data sets that can be processed
- 18 bit internal data bus with block floating point arithmetic leads to increased dynamic range, greater accuracy, and an enhanced signal-to-noise ratio
- 500 MIP operation gives 87 microsecond transformation times for 1024 points, enabling fast and accurate signal processing
- Up to 45MHz sampling rates with multiple devices
- Up to 85dB noise rejection and a choice of internal window operators with no external ROM provide up to 67dB side lobe attenuation, leading to more accurate data processing and improved signal quality
Disadvantages- Not suitable for applications that do not require Fourier Transform processing
- Available in only two packaging options, which may not meet the needs of all applications
