DP83867IS: DP83867IS datasheet IO_Impedance_ctrl

Part Number: DP83867IS


Hi Team,

DP83867IS datasheet mentioned about IO_IMPEDANCE_CTRL at Page 87.  Please clarify, is it relate to RX signal data and clock output impedance setting or for TX related or both.  And also share the exact formula to calculate the impedance value in the hexa decimal for given steps.

if for both rx and tx impedance control: how can match  proper impedance for rx signals and tx signals. tx signals are driving from controller and rx signals are driving from the Phy.
