JAJSLL2B April 2021 – November 2021 DP83561-SP
PRODUCTION DATA
The DP83561-SP uses many of the functional pins as strap options to place the device into specific modes of operation. The values of these pins are sampled at power up or hard reset. During software resets, the strap options are internally reloaded from the values sampled at power up or hard reset. The strap option pin assignments are defined below.
Configuration of the device may be done through strap pins or through the management register interface. A pullup resistor and/or a pulldown resistor of suggested values may be used to set the voltage ratio of the strap pin input and the supply to select one of the possible selected modes.
The MAC interface pins must support I/O voltages of 3.3 V, 2.5 V, and 1.8 V. As the strap inputs are implemented on these pins, the straps must also support operation at 3.3-V, 2.5-V, and 1.8-V supplies depending on what voltage was selected for I/O. RX_D0 and RX_D1 pins are 4 level strap pins. All other strap pins have two levels.
