Maximum Frequency
FMAX With all registers used 891 775 645 644 MHz
FMAX_PATDET With pattern detector 794 687 571 562 MHz
FMAX_MULT_NOMREG Two register multiply without MREG 635 544 456 440 MHz
FMAX_MULT_NOMREG_PATDET Two register multiply without MREG with pattern detect 577 492 410 395 MHz
FMAX_PREADD_NOADREG Without ADREG 655 565 468 453 MHz
FMAX_NOPIPELINEREG Without pipeline registers (MREG, ADREG) 483 410 338 323 MHz
FMAX_NOPIPELINEREG_PATDET Without pipeline registers (MREG, ADREG) with pattern detect 448 379 314 299 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.
