RESET Initialization
4.2
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.
(CLKIN/PCI_CLK) AC timing specifications for the device.

Notes:
1. Caution: The system, core, USB, security, and 10/100/1000 Ethernet must not exceed their respective maximum or
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
minimum operating frequencies.
low to allow cascade-connected PLL-based devices to track CLKIN drivers with the specified jitter.
