Clock Input Timing
This section provides the clock input DC and AC electrical characteristics for the device.
4.1
DC Electrical Characteristics
Table 6 provides the clock input (CLKIN/PCI_SYNC_IN) DC timing specifications for the MPC8349EA.
4.2
AC Electrical Characteristics
The primary clock source for the MPC8349EA can be one of two inputs, CLKIN or PCI_CLK, depending
on whether the device is configured in PCI host or PCI agent mode. Table 7 provides the clock input
(CLKIN/PCI_CLK) AC timing specifications for the device.

Notes:
1. Caution: The system, core, USB, security, and TSEC must not exceed their respective maximum or minimum operating
frequencies.
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
allow cascade-connected PLL-based devices to track CLKIN drivers with the specified jitter.
6. Spread spectrum clocking is allowed with 1% input frequency down-spread at maximum 50 KHz modulation rate regardless
of input frequency.
