Notes to Table 1–36:
(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) This is only applicable to the Stratix IV E and GX devices.
(3) When you use the error detection CRC feature, there is no degradation in F_MAX.
