PDSP16116 16 X 16 Bit Complex Multiplier Supersedes October 1996 version, DS3707 - 4.2 DS3707 - 5.3 October 1997 The PDSP16116 contains four 16316 array multipliers, two 32-bit adder/subtractors and all the control logic required to support Block Floating Point Arithmetic as used in FFT applications.

The PDSP16116A variant will multiply two complex (16116) bit words every 50ns and can be configured to output the complete complex (32132) bit result within a single cycle.

The data format is fract
