Working Principles

The LTC2858IDD-2#PBF operates based on the principles of differential signaling. It uses two complementary signals, one inverted and one non-inverted, to transmit data. This technique provides excellent noise immunity, as any common-mode noise is rejected by the receiver.

When enabled, the driver amplifies the input signal and transmits it differentially through the Y and Z pins. The receiver then detects the differential signal and outputs the received data through the RO pin.
