PDSP16515MA规格书详情
The PDSP16515A performs Forward or Inverse Fast Fourier Transforms on complex or real data sets containing up to 1024 points. Data and coefficient input are both represented by 16 bits. Data is expanded internally to 18 bits and subject to Block Floating Point arithmetic to preserve a greater dynamic range. An internal RAM is provided which can hold up to 1024 complex data points. This removes the memory transfer bottleneck, inherent in building block solutions. Its organisation allows the PDSP16515A to
simultaneously input new data, transform data stored in the RAM, and to output previous results. No external buffering is needed for transforms containing up to 256 points, and the PDSP16515A can be directly connected to an A/D converter to perform continuous transforms. The user can choose to overlap data blocks by either 0, 50, or 75. Inputs and outputs are synchronous to the 45MHz system clock used for internal operations.
Features
● Completely self contained FFT Processor
● Pin and functionally compatible with the PDSP16510A
● Expanded width internal RAM supports up to 1024 complex points
● 18 bit internal data bus with 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
● A choice of internal window operators with no
external ROM provide up to 67dB side lobe
attenuation.
● 84 pin PGA or 132 pin surface mount package
