Freescale Semiconductor
AC Electrical Characteristics
Table 12 lists SIU output characteristics.
NOTE
Activating data pipelining (setting BRx[DR] in the memory controller) improves
the AC timing.
Table 12. AC Characteristics for SIU Outputs 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.
