Notes to Table 33:
(1) To achieve the maximum memory block performance, use a memory block clock that comes through global clock routing from an on-chip PLL
set to 50% output duty cycle. Use the Quartus II software to report timing for this and other memory block clocking schemes.
(2) When you use the error detection cyclical redundancy check (CRC) feature, there is no degradation in FMAX
.
(3) The FMAX specification is only achievable with Fitter options, MLAB Implementation In 16-Bit Deep Mode enabled.
