11.2.8. Frequency of Operation
In most cases, the frequency and parameter combination is not optimal. If you are using a memory device that has tRCD = 15 ns and running the interface at 1200 MHz, you get the following results:
- For quarter-rate implementation (tCk = 3.33 ns):
tRCD convert to clock cycle = 15/3.33 = 4.5, rounded up to 5 clock cycles or 16.65 ns.
In most cases, the frequency and parameter combination is not optimal. If you are using a memory device that has tRCD = 13.09 ns and running the interface at 933 MHz, you get the following results:
- For quarter-rate implementation (tCk = 4.29 ns):
tRCD convert to clock cycle = 13.09/4.29 = 3.05, rounded up to 4 clock cycles or 17.16 ns.
