Summary0000867: About DDR layout option
DescriptionBranched from 0000840: [SWAN] Schematic, PCB, new items.

Dear Sean
You mentioned as below(0003633) with attached file.
"Hi SB,
 Please find attached for the picture of the DDR layout option captured from Synaptics FAE email."
I found there are some different with FAE's comment and real application.
1. FAE Comment: 6Layer PCB and DDR3L
2. Real application: 6Layer PCB and DDR4
In DDR4 application, is it acceptable with top and bottom layout?

Best regards

Lonnie Kim

Hi Lonnie

We are now using 4pcs DDR4 on the same side design instead of the design mentioned in the email you see in attachment.

Sean
