RGMII Routing Constraints (Reduced Gigabit Media Independent Interface):
The RGMII signals must be length-matched by TX and RX groups.
That is, the TX group should be matched within 0.25 inch (6.35 mm),
and the RX group should be matched within 0.25 inch (6.35 mm).
Total length should not exceed 1.75 inch (44.5 mm).
There is no requirement to match the TX and RX groups
because their clocks are not related.

Cl=Cs+[C1xC2]/[C1+C2]
if C1=C2 =>
C1,2=2[Cl-Cs] !!!
Cl is load capacitance of the cristal.
CS is the stray capacitance on the
printed circuit board,
typically a value of 5pf can be used
for calculation
