AM335x DDR3 Track Impedances

Hi,

This will be a similar question posted in the below E2E.
http://e2e.ti.com/support/dsp/c6000_multi-core_dsps/f/639/t/120284.aspx#451726

In case of AM335x DDR3, what are the track impedances for single ended & differential signals.

Will the below statement applicable for AM335x's DDR3 interface?

"The differential signals should be 100ohm differential.  
The impedance of the single ended tracks should be matched but they can 
all be implemented at a value higher then 50 ohms"

Regards.
