4.1
DC Electrical Characteristics
This table provides the clock input (CLKIN/PCI_CLK) DC timing specifications for the device.
4.2
AC Electrical Characteristics
The primary clock source for the device can be one of two inputs, CLKIN or PCI_CLK, depending on
whether the device is configured in PCI host or PCI agent mode. This table provides the clock input
(CLKIN/PCI_CLK) AC timing specifications for the device.

Notes:
1. Caution: The system, core and security block must not exceed their respective maximum or minimum operating
frequencies.
2. Rise and fall times for CLKIN/PCI_CLK are measured at 0.4 V 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 is allowed up to 1% down-spread on CLKIN/PCI_CLK up to 60 KHz.
