Clock Input Timing

4.1

DC Electrical Characteristics

Table 7 provides the clock input (CLKIN/PCI_SYNC_IN) 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. Table 8 provides the clock input

(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 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.
