Electrical and Thermal Characteristics
Table 10 lists SIU output characteristics.
NOTE
Activating data pipelining (setting BRx[DR] in the memory controller)
improves the AC timing. When data pipelining is activated, sp12 can be
used for data bus setup even when ECC or PARITY are used. Also, sp33a
can be used as the AC specification for DP signals.
Table 10. AC Characteristics for SIU Outputs1
1 Output specifications are measured from the 50% level of the rising edge of CLKIN to the 50% level of the signal.
Timings are measured at the pin.
