Figure 4
Clock, CKE and Command/Address Timings
Setup and Hold Timing for CKE is equal to CMD and ADDR Setup and Hold Timing. The DLL ensures the
alignment of DQs and CLK. Therefore the preferred operation mode for high frequencies is DLL on. The DLL
frequency range is from 600 MHz down to 250 MHz.
