PCI9054-AC50PI datasheet by PLX Technology

PCI9054-AC50PI Frequently Asked Questions (FAQs)

• What is the maximum power consumption of the PCI9054-AC50PI?
  The maximum power consumption of the PCI9054-AC50PI is 2.5W, with a typical power consumption of 1.5W.
• How do I configure the PCI9054-AC50PI for 64-bit or 32-bit operation?
  The PCI9054-AC50PI can be configured for 64-bit or 32-bit operation through the use of external resistors on the AD[31:0] pins. For 64-bit operation, the resistors should be connected to VCC, and for 32-bit operation, they should be connected to GND.
• What is the maximum clock frequency supported by the PCI9054-AC50PI?
  The PCI9054-AC50PI supports clock frequencies up to 66MHz.
• How do I implement a reset circuit for the PCI9054-AC50PI?
  A reset circuit can be implemented using a resistor-capacitor (RC) network connected to the RST# pin. The recommended values are R = 1kΩ and C = 100nF.
• What is the purpose of the PERST# pin on the PCI9054-AC50PI?
  The PERST# pin is an output that indicates when the PCI Express link is up and running. It can be used to reset other components on the board.
