PRODUCTION DATA
Refer to the PDF data sheet for device specific package drawings
The DP83867IRPAP can be set to respond to any of 32 possible PHY addresses via strap pins. DP83867IRRGZ/CRRGZ support 16 addresses. The information is latched into the device at a device power up or hardware reset. Each DP83867 or port sharing an MDIO bus in a system must have a unique physical address. The DP83867IRPAP supports PHY address strapping values 0 (<00000>) through 31 (<11111>). DP83867IRRGZ/CRRGZ support PHY addresses from 0(<0000>) to 16(<1111>).
For further detail relating to the latch-in timing requirements of the PHY Address pins, as well as the other hardware configuration pins, refer to Section 7.5.5.
Based on the default strap configuration of PHY_ADD[4:0], the DP83867 PHY address will initialize to 0x00 without any external strap configuration.
Refer to Figure 7-15 for an example of a PHY address connection to external components. In this example, the pins are configured as follows: RX_D4 = Strap Mode 4, RX_D2 = Strap Mode 3, and RX_D0 = Strap Mode 2. Therefore, the PHY address strapping results in address 11001 (19h).
