Preliminary Electrical Characteristics
5.7.2
When the SDRAM controller is configured for DDR SDRAM, the following timing numbers must be followed to properly latch
or drive data onto the memory bus. All timing numbers are relative to the four DQS byte lanes. The following timing numbers
are subject to change at anytime, and are only provided to aid in early board design.

The frequency of operation is either 2x or 4x the FB_CLK frequency of operation. FlexBus and SDRAM clock operate at the
same frequency as the internal bus clock.
SD_CLK is one SDRAM clock in (ns).
Pulse width high plus pulse width low cannot exceed min and max clock period.
Command output valid should be 1/2 the memory bus clock (SD_CLK) plus some minor adjustments for process, temperature,
and voltage variations.
This specification relates to the required input setup time of today’s DDR memories. The device’s output setup should be larger
than the input setup of the DDR memories. If it is not larger, then the input setup on the memory will be in violation.
SD_D[31:24] is relative to SD_DQS3, SD_D[23:16] is relative to SD_DQS2, SD_D[15:8] is relative to SD_DQS1, and
SD_D[7:0] is relative SD_DQS0.
The first data beat will be valid before the first rising edge of DQS and after the DQS write preamble. The remaining data beats
will be valid for each subsequent DQS edge.
This specification relates to the required hold time of today’s DDR memories. SD_D[31:24] is relative to SD_DQS3,
SD_D[23:16] is relative to SD_DQS2, SD_D[15:8] is relative to SD_DQS1, and SD_D[7:0] is relative SD_DQS0.
