The primary potential issue with dual-stripline trace layers is crosstalk.
Characterization of crosstalk between signal layers is a must, unless you
are routing the traces orthogonally. Routing the two layers in the same
direction introduces huge broadside crosstalk problems, and if you do the
math you will find that you can route less traces per linear inch on two
parallel broadside layers, than if you introduced a ground plane between
them ... and ... that the total area is also less to maintain crosstalk
control
Good luck.

you may have to route high speed traces orthogonaly. have SERDES on outer
layer and can have ddr on inner layer.

That's up to how well you implement it! There is nothing wrong with the
technology in and of itself, but the problem areas are typically
transitions
to/from parts and routing near objects that affect the local impedance.
Will
this be an over/under or side by side approach? There are pluses and
minuses
to each.

Hi
I am planning to design a PCB board using Dual Stipline. The board has
several high speed interfaces like DDR , PCIe ,USB3.0 .
Will there be any product issues if we use Dual Stripline
Thanks & Regards
