16 X 12 BIT COMPLEX MULTIPLIER

The PDSP16112/PDSP16112A will multply a complex (16+16) bit word by a complex (12+12) bit coefficient word and produce a complex (17+17) bit rounded product. FEATURES ■ 20MHz Complex Number (16+16) x (12+12) Multplication ■ Pipeline Architecture ■ Power Dissipation only 500mW ■ TTL Compatible

16 by 16 Bit Complex Multiplier

The PDSP16116A will multiply two complex (16 + 16) bit words every 50ns and can be configured to output the complete complex (32 + 32) bit result within a single cycle. The data format is fractional twos complement. FEATURES ■ Complex Number (16 + 16) X (16 + 16) Multiplication ■ Full 32 bit Re

Complex Accumulator

The PDSP16318 contains two independent 20-bit Adder/Subtractors combined with accumulator registers and shift structures. The four port architecture permits full 10MHz throughout in FFT and filter applications. Two PDSP16318s combined with a single PDSP16112A Complex Multiplier provide a complete
