Hi all,
I have looked at the Mistral DM814x & AM3874 Base Board documentation (gerber) and could not able to confirm the 1st and 2nd impedance requirements.
All my calculation are same for given stackup except the diff pairs on layer 5 and 6. (I am using SaturnPCB Toolkit. http://saturnpcb.com/pcb_toolkit.htm )
Diff pairs on layer 5 and 6 seems assymetrical stripline but my findings are not 90 and 100 ohm repectly for 1st and 2nd requirement.
Could some one help me how to calculate (confirm) 1st & 2nd impedance requirement with SaturnPCB Toolkit or any other free tool ?
The picture below shows impedance requirements and stackup.
Best Regards.
