DP83867E: MDIO requires pullup resistor

Part Number: DP83867E

Hi

The MDIO of DP83867E requires external pullup resistor.

The IEEE specified this resistor value is 1.5kohm but the device datasheet says 2.2kohm can be acceptable.

What is the impact of this difference?

Regarding to the DP83867E, is 2.2kohm value better choice for pullup at MDIO?

BestRegards
