DP83TC813R-Q1: RGMII delay setting

Part Number: DP83TC813R-Q1

Tool/software:

Hi Melissa,

My customer have three questions about RGMII delay:

1. When setting the delay in RGMII TX Spec, the measurement point is thought to be Told(shift) / Tsetup(shift).
However, only Tsetup(align) / Told(align) was found in the datasheet. Could you tell me Told(shift)/Tsetup(shift) value?

2. When setting delay in RGMII RX Spec, the measurement point is thought to be Tskew (shift).
Only Tskew(align) / Tsetup(shift) was found in the datasheet. Please let me know about Tskew (shift) value.

3. Is Tsetup(shift) in the datasheet different from Tsetup(shift) in TX?

Regards,

Youhei MIYAOKA
