Product Summary
The PDSP16318ACO is an independent 20-bit Adder/ Subtractor combined with accumulator registers and shift structures. The four port architecture permits full 20MHz throughout in FFT and filter applications. The PDSP16318ACO combined with a single Complex Multiplier provide a complete arithmetic solution for a Radix 2 DIT FFT Butterfly. A new complex Butterfly result can be generated every 50ns allowing 1K complex FFTs to be executed in 256μs. applications are (1)High speed Complex FFT or DFTs; (2)Complex Finite Impulse Response (FIR)Filtering; (3)Complex Conjugation; (4)Complex Correlation/Convolution.
