7.5.1 Strap Configuration

The DP83867 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. The functional pin name is indicated in parentheses.

The strap pins supported are 4-level straps, which are described in greater detail below.

Note:

Because strap pins may have alternate functions after reset is deasserted, they should not be connected directly to VDD or GND.

Configuration of the device may be done through the 4-level strap pins or through the management register interface. A pullup resistor and a pulldown resistor of suggested values may be used to set the voltage ratio of the 4-level strap pin input and the supply to select one of the possible selected modes.

The MAC interface pins must support I/O voltages of 3.3V, 2.5V, and 1.8V. As the strap inputs are implemented on these pins, the straps must also support operation at 3.3V, 2.5V, and 1.8V supplies.

For more information about configuring 4-level straps, see the Configuring Ethernet Devices with 4-Level Straps application report (SNLA258).

For SGMII Mode 4 strap, TI recommends using Rhi = 4kΩ and Rlo = 10kΩ on RX_D0 and RX_D1 , RX_D2 and RX_D3.

All straps have a 9kΩ ±25% internal pulldown resistor. The voltage at strap pins should be between the Vmin and Vmax mentioned in the Target Voltage column in Table 7-5. Strap resistors with 1% tolerance are recommended.

The following tables describes the DP83867 configuration straps:

(1) Strap modes 1 and 2 are not applicable for RX_CTRL. The RX_CTRL strap must be configured for strap mode 3 or strap mode 4. If the RX_CTRL pin cannot be strapped to mode 3 or mode 4, bit[7] of Configuration Register 4 (address 0x0031) must be cleared to 0. Autoneg Disable should always be set to 0 when using gigabit Ethernet.
(2) Only Mode 1 and 3 are valid for GPIO_0. Mode 2 and 4 are not applicable and should not be used.
Note:

RX_D1 is not a strap input, but this pin must be populated with the same strap resistors chosen for RX_D0. RX_D0 and RX_D1 form an SGMII differential pair. The dummy straps on RX_D1 are required to provide a balanced load for this SGMII differential pair.

Note:

RX_D3 is not a strap input, but this pin must be populated with the same strap resistors chosen for RX_D2. RX_D2 and RX_D3 form an SGMII differential pair. The dummy straps on RX_D3 are required to provide a balanced load for this SGMII differential pair.
