PRODUCTION DATA
The REF0_PCIE and REF1_PCIE terminals connect to an external resistor to set the drive current for the PCI Express TX driver. The recommended resistor value is 14,532 Ω with 1% tolerance.
A 14,532- Ω resistor is a custom value. To eliminate the need for a custom resistor, two series resistors are recommended: a 14,300- Ω , 1% resistor and a 232- Ω , 1% resistor. Trace lengths must be kept short to minimize noise coupling into the reference resistor terminals.
