DESIGN GUIDELINES
Release 1.3 - January 29, 2002
65/87
This is preliminary information on a new product now in development or undergoing evaluation. Details are subject to change without notice.
6.3.4. PCI BUS
The PCI bus is always active and the following
control signals must be pulled-up to 3.3V or 5V
through 2K2 resistors even if this bus is not
connected to an external device: FRAME#,
TRDY#, IRDY#, STOP#, DEVSEL#, LOCK#,
SERR#, PCI_REQ#[2:0].
PCI_CLKO must be connected to PCI_CLKI
through a 10 to 33 Ohms resistor.
Figure 6-7
shows a typical implementation.
For more information on layout constraints, go to
the
place and route recommendations
section.
In the case of higher clock load it is recommended
to use a zero-delay clock buffer as described in
Figure 6-8
. This approach is also recommended

according to the PCI section of the

Specifications
