Maximum Frequency
FMAX UltraRAM maximum frequency with OREG_B = True 600 575 500 495 481 MHz
FMAX_ECC_NOPIPELINE UltraRAM maximum frequency with OREG_B = False and EN_ECC_RD_B = True 400 386 312 303 303 MHz
FMAX_NOPIPELINE UltraRAM maximum frequency with OREG_B = False and EN_ECC_RD_B = False 500 478 404 389 389 MHz
TPW 1 Minimum pulse width 700 730 800 832 832 ps
TRSTPW Asynchronous reset minimum pulse width. One cycle required 1 clock cycle
  1. The MMCM and PLL DUTY_CYCLE attribute should be set to 50% to meet the pulse-width requirements at the higher frequencies.
