PDSP16318/A Complex Accumulator
| Product Status - Obsolete |
|
The PDSP16318/A contains two independent 20-bit Adder/Subtractors combined with accumulator registers and shift structures. The four port architecture permits full 20 MHz throughout in FFT and filter applications. Two PDSP16318As combined with a single PDSP16112A Complex Multiplier provide a complete arithmetic solution for a Radix 2 DIT FFT Butterfly. A new complex Butterfly result can be generated every 50 ns allowing 1 K complex FFTs to be executed in 256 ms.
