SN65LVDS104: SN65LVDS104 LVDS AC coupled

Dung Huynh

Part Number: SN65LVDS104

Tool/software:

For LVDS AC coupled, does SN65LVDS104 output require DC path (a resistor between P and N outputs)?

For LVDS AC coupled, does SN65LVDS104 input require external bias? if it does, what is the recommended external bias circuit?

Thank you.

Outputs can be left open and do not require a DC Path.

For the inputs, see How to Terminate LVDS Connections.

Hi Dung,

Clemens is correct. The driver (SN65LVDS104) does not require a DC path. Only the receiver will need a DC path. An external bias is needed on the receiver if the receiver does not have a wide common mode range. Please refer to the app note Clemens linked in his response for more details/examples.

Regards,

Matt
