2.2.2.4. Memory Block Specifications

Table 114.  Memory Block Performance Specifications for Arria V GZ Devices

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 Intel® Quartus® Prime software to report timing for this and other memory block clocking schemes.

When you use the error detection cyclical redundancy check (CRC) feature, there is no degradation in FMAX.
