SIU AC Characteristics
Table 11 lists SIU input characteristics.
NOTE: CLKIN Jitter and Duty Cycle
The CLKIN input to the MPC8272 should not exceed +/– 150 psec. This
represents total input jitter—the combination of short term (peak-to-peak)
and long term (cumulative). The duty cycle of CLKIN should not exceed the
ratio of 40:60.
NOTE: Spread Spectrum Clocking
Spread spectrum clocking is allowed with 1% input frequency down-spread
at maximum 60 KHz modulation rate regardless of input frequency.
NOTE: PCI AC Timing
The MPC8272 meets the timing requirements of PCI Specification Revision
2.2. Refer to Section 7, “Clock Configuration Modes,” and “Note: Tval
(Output Hold)” to determine if a specific clock configuration is compliant.
