50 Mbps full-duplex transceiver for long-haul industrial links
The built-in 70 mV receiver hysteresis cleans up reflections and ground offsets on long cable runs without external Schmitt-trigger components. The full-duplex architecture supports simultaneous transmit and receive on a four-wire bus, typical in point-to-point encoder feedback and multi-drop PLC backplanes.
70 mV hysteresis — why it matters on a noisy bus
The 70 mV receiver hysteresis is the difference between the rising and falling input thresholds. On a 50 Mbps link, cable reflections and ground shifts can inject noise that crosses a zero-hysteresis threshold multiple times per bit, causing bit errors or receiver chatter.
