Part Number: DP83867IR

DP83867IRRGZ is about to be replaced by DP83867IRPAP. Should I change the setting of strap to the following? How do I set the Clock Skew? Also, what should I do with Force MDI/X, Half-Duplex Enable, RGMII Disable, AMDIX Disable, Speed Optimization Enable, Clock Out Disable, and Fast Link Detect, which are only available with DP 83867 IRPAP?Are there any other changes required in the host software?

(strap settings)
PHY _ ADD: 1100 - > 01100
ANEG _ SEL: 0 - > 00
Autoneg Disable: 0 → 0
RGMII Clock Skew TX: 000 →?
RGMII Clock Skew RX: 000 →?

Hello,

For RGMII Clock Skew settings, I suggest you look in registers 0x0086 and 0x0032.

Looking at the modifications above to the strap settings, I think the setup will work once the values in registers 0x0086 and 0x0032 are tweaked for the best performance with your design.

Kind Regards,

Joe
