Maximum Frequency
FMAX With all registers used 775 645 600 MHz
FMAX_PATDET With pattern detector 687 571 524 MHz
FMAX_MULT_NOMREG Two register multiply without MREG 544 456 413 MHz
FMAX_MULT_NOMREG_PATDET Two register multiply without MREG with pattern detect 492 410 371 MHz
FMAX_PREADD_NOADREG Without ADREG 565 468 423 MHz
FMAX_NOPIPELINEREG Without pipeline registers (MREG, ADREG) 410 338 304 MHz
FMAX_NOPIPELINEREG_PATDET Without pipeline registers (MREG, ADREG) with pattern detect 379 314 280 MHz
  1. For devices operating at the lower power VCCINT = 0.72V voltages, DSP cascades that cross the clock region center might operate below the specified FMAX.
