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.
Spread spectrum clocking is allowed with 1% input frequency down-spread
at maximum 60 KHz modulation rate regardless of input frequency.
The MPC8272 meets the timing requirements of PCI Specification Revision
2.2. Refer to
(Output Hold)” to determine if a specific clock configuration is compliant.
Note: TGATE is asserted on the rising edge of the clock; it is deasserted on the falling edge.
