Hello MX users,

i have a question about the i.MX6 Routing, actually i have matched all Lines but i need a Informations about the Clock Length Calulation.

Whath of the following 2 calculation sheems is the Right:

1. With Termination Resistor Length

i get A Complete Length of 2120 mils per Clock Line ( CLK X + /-)

2. Without Termination Resistor Length

i get a Complete Length of 2450 mils per Clock Line ( CLK X + /-)

What is the right value? I need it for the Rule Adress = max Clock -200 mils...
