4.2
The primary clock source for the MPC8343E can be one of two inputs, CLKIN or PCI_CLK, depending
on whether the device is configured in PCI host or PCI agent mode.
(CLKIN/PCI_CLK) AC timing specifications for the MPC8343E.

CLKIN/PCI_CLK jitter
Notes:
1. Caution: The system, core, USB, security, and TSEC must not exceed their respective maximum or minimum operating
2. Rise and fall times for CLKIN/PCI_CLK are measured at 0.4 and 2.7 V.
3. Timing is guaranteed by design and characterization.
4. This represents the total input jitter—short term and long term—and is guaranteed by design.
5. The CLKIN/PCI_CLK driver’s closed loop jitter bandwidth should be <500 kHz at –20 dB. The bandwidth must be set low to
frequencies.
allow cascade-connected PLL-based devices to track CLKIN drivers with the specified jitter.
