Working Principles

The SN65LVDT348D operates based on the LVDS signaling standard, which uses differential voltage levels to transmit data. It receives parallel data inputs and converts them into serial LVDS signals for transmission. On the receiving end, it converts the received LVDS signals back into parallel data.

The transceiver incorporates fail-safe biasing, which ensures that the outputs are in a known state when the inputs are not being driven. This feature enhances the reliability of the communication link.
