Input specifications are measured from the 50% level of the signal to the 50% level of the rising edge of CLKIN. Timings are

CLKIN jitter and duty cycle. The CLKIN input to the MPC8280 should not exceed +/– 150 psec of jitter
(peak-to-peak). This represents total input jitter—the combination of short term (cycle-to-cycle) and long
term (cumulative). The duty cycle of CLKIN should not exceed the ratio of 40:60. The rise/file time of
CLKIN should adhere to the typical SDRAM device AC clock requirement of 1 V/ns to meet SDRAM AC
specs.
Spread spectrum clocking. Is allowed with 1% input frequency down-spread at maximum 60 KHz
modulation rate regardless of input frequency.
PCI AC timing. The MPC8280 meets the timing requirements of PCI Specification Revision 2.2. Refer to
Sections 7.2 and 7.3 and “Note: Tval (Output Hold)” to determine if a specific clock configuration is
compliant.
Activating data pipelining (setting BRx[DR] in the memory controller) improves the AC timing.
