Hi sir,

A customer is intending to purchase SN65LVDS387
I want to ask that will it also convert TTL5v to LVDS 2.5.

Thanks.

Hi Frank,

The DS90C031B will convert 5V TTL to LVDS. You will need to clarify what you mean by "2.5V LVDS" though, since LVDS has a standard output of 1.2V common mode and 350mV swing.

Hi I.K.,

I meant to ask I need LVDS_25 standard ( the way it is defined in FPGA)
I have to send this data to FPGA bank that has a biasing of 2.5V.

Thank you.

Hi Frank,

You just need to check if the common mode voltage and differential voltage is compatible.
