Working Principles

LTC2851MPMS8#TRPBF operates based on the principles of differential signaling. It uses a driver to convert digital signals into balanced differential voltages, which are then transmitted over twisted-pair cables. The receiver at the other end of the communication line converts the differential voltages back into digital signals.

The differential signaling technique provides excellent noise rejection, allowing reliable data transmission even in electrically noisy environments. The built-in fail-safe biasing ensures that the bus remains in a known state during idle conditions.
