Description
The PDSP16515A is an electronic component model in the product category of IC Chips. It is designed to perform Forward or Inverse Fast Fourier Transforms on complex or real data sets containing up to 1024 points. The data and coefficient input are both represented by 16 bits, which are internally expanded to 18 bits for greater dynamic range. The PDSP16515A features an internal RAM that can hold up to 1024 complex data points, eliminating the need for external buffering. It can simultaneously input new data, transform data stored in the RAM, and output previous results. The inputs and outputs are synchronous to the 45MHz system clock used for internal operations.
