PCI9052 datasheet by PLX Technology

PCI9052 Frequently Asked Questions (FAQs)

• What is the maximum power consumption of the PCI9052?
  The maximum power consumption of the PCI9052 is 1.5W, with a typical power consumption of 1.2W.
• How do I configure the PCI9052 for 32-bit or 64-bit bus operation?
  The PCI9052 can be configured for 32-bit or 64-bit bus operation through the use of external resistors on the AD[31:0] pins. For 32-bit operation, tie AD[31:16] to VCC, and for 64-bit operation, tie AD[31:16] to GND.
• What is the maximum clock frequency supported by the PCI9052?
  The PCI9052 supports clock frequencies up to 66MHz.
• How do I implement a reset circuit for the PCI9052?
  A reset circuit can be implemented using a resistor and capacitor connected to the RST# pin. The recommended values are a 1kΩ resistor and a 10nF capacitor.
• What is the purpose of the PERST# pin on the PCI9052?
  The PERST# pin is an output that indicates when the PCI9052 is in a reset state. It can be used to reset other devices on the PCI bus.
