Hi,
The impedance is correct. I can review the layout once it is completed.
Thanks

Hi David
Could you help with check the schematic.
customer change RGZ to RSB and try to place 2 DP159.
Hi Gareth,
I reviewed your schematic and it looks good for the most part.
Some recommendations based on what I could see in your schematic:
On your Pin 19 of DP159, I would recommend one 100 nF cap on the pin and 4.7 pF, 10 pF and one bulky caps on each power node.
I saw a CM choke and ESD implemented on the 2nd page of your schematic for one DP159 but not for the DP159 on the last page.
I would suggest implementing the CM choke and ESD for both DP159 signal paths.
Thanks,
Zach
