PCI2040PGE datasheet by Texas Instruments

PCI2040PGE Frequently Asked Questions (FAQs)

• What is the recommended operating temperature range for the PCI2040PGE?
  The recommended operating temperature range for the PCI2040PGE is -40°C to 85°C.
• How do I configure the PCI2040PGE for 3.3V or 5V operation?
  The PCI2040PGE can be configured for 3.3V or 5V operation by connecting the VCC pin to the desired voltage supply. Additionally, the I/O voltage (VIO) pin should be connected to the same voltage supply as the VCC pin.
• What is the maximum clock frequency supported by the PCI2040PGE?
  The maximum clock frequency supported by the PCI2040PGE is 66 MHz.
• How do I implement a reset circuit for the PCI2040PGE?
  A reset circuit can be implemented using a resistor and capacitor connected to the RESET# pin. The recommended values are a 1 kΩ resistor and a 0.1 μF capacitor.
• What is the purpose of the PERST# pin on the PCI2040PGE?
  The PERST# pin is an active-low reset input that resets the PCI interface. It is typically connected to a power-on reset circuit or a manual reset switch.
