RTL8201CL datasheet by Realtek Semiconductor

RTL8201CL Frequently Asked Questions (FAQs)

• What is the recommended operating temperature range for the RTL8201CL?
  The recommended operating temperature range for the RTL8201CL is 0°C to 70°C (commercial temperature range) and -40°C to 85°C (industrial temperature range).
• How do I configure the RTL8201CL for half-duplex or full-duplex operation?
  The RTL8201CL can be configured for half-duplex or full-duplex operation through the DUPLEX pin. Connecting the DUPLEX pin to VCC configures the device for full-duplex operation, while connecting it to GND configures it for half-duplex operation.
• What is the maximum transmission distance supported by the RTL8201CL?
  The maximum transmission distance supported by the RTL8201CL is 100 meters (328 feet) over Category 5e cable, assuming a 100BASE-TX connection.
• How do I implement power management in the RTL8201CL?
  The RTL8201CL has a built-in power management feature that can be controlled through the PWON pin. Asserting the PWON pin low puts the device in power-down mode, while de-asserting it returns the device to normal operation.
• What is the maximum clock frequency supported by the RTL8201CL?
  The RTL8201CL supports a maximum clock frequency of 25 MHz.
