PDSP16116 Datasheet 16 By 16 Bit Complex Multiplier

Manufacturer: Zarlink Semiconductor

Overview: www.DataSheet4U.com PDSP16116/A/MC 16 by 16 Bit Complex Multiplier PDSP16116/A/MC DS3858 ISSUE 3.0 June 2000 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 two's complement. The PDSP16116/A contains four 16 x 16 Array Multipliers, two 32 bit Adder/Subtractors and all the control logic required to support Block Floating Point Arithmetic as used in FFT applications. In combination with a PDSP16318, the PDSP16116A forms a two chip 10MHz Complex Multiplier Accumulator with 20 bit accumulator registers and output shifters. The PDSP16116 in combination with two PDSP16318s and two PDSP1601s forms a complete 10MHz Radix 2 DIT FFT Butterfly solution which fully supports Block Floating Point Arithmetic. The PDSP16116/A has an extremely high throughput that is suited to recursive algorithms as all calculations are performed with a single pipeline delay (two cycle fall-through).
