SN75LVPE5421: SN75LVPE5421

Hi Michael,

SN75LVPE5421 is protocol agnostic and is typically used for AC-coupled interfaces such as PCI Express, UPI, CCIX, NVLink, DisplayPort, SAS, SATA, and XFI. 
The device can be implemented similarly to a PCIe application, only difference is that the RX detection functionality can be turned off for non-PCIe protocols. Please refer to Section 7 of the data sheet for further application information.

Please also note the SN75LVPE5412, which is a companion de-multiplexer device - if you are interested as well.

Best,
David

We are running sFPDP signals at 25Gbps. Can we use SN75LVPE5421 for mux the sFPDP signals? 

Hi Michael,

I am not familiar with the electrical spec of sFPDP. Could you help to share this information or point me towards a specification?

Best,
David

Hi Michael,

Thank you for sharing this reference.

It is still not quite clear what the electrical specs are like for this specification based on their provided data sheet.

My primary concern is what type of signaling this protocol uses. This device is typically used with PCIe transmitters, where source differential launch amplitude between 800-1200mVpp. Do you know if this information is available from the vendor?

Best,
David

it is AC coupled.
