Application Information
Decoupling Capacitors
Decoupling capacitors of 0.01μF or 0.1μF must be connected
between each VDD pin and the PCB ground plane and placed
as close to the VDD pin as possible.
PI6C557-05 must be isolated from system power supply noise to
perform optimally.
Crystal
Use a 25MHz fundamental mode parallel resonant crystal with
less than 30PPM of error across temperature.
Current Source (Iref) Reference Resistor - RR
If board target trace impedance is 50-Ohm,
then RR = 475-Ohm providing an IREF of 2.32 mA. The output
current (IOH) is 6*IREF.
Output Termination
The PCI-Express differential clock outputs of the PI6C557-05
are open source drivers and require an external series resistor
and a resistor to ground. These resistor values and their allow-
able locations are shown in detail in the PCI-Express Layout
Guidelines section.
The PI6C557-05 can be configured for LVDS compatible voltage
levels. See the LVDS Compatible Layout Guidelines section.
