Description
AI
The SN65HVD61 is designed to meet the requirements for the driver and receiver circuitry of the ControlNet coaxial-based physical layer.
These devices are single-channel circuits with one transceiver for single node operation or distributed stand-alone applications.
The pull-or-pull transmitter circuit is designed to sink current from a center-tapped transformer, providing galvanic isolation from the shared bus.
These devices incorporate a differential receiver (RX) with the 120 mV sensitivity needed by ControlNet industrial applications.
A secondary receiver (CD) detects the presence of a valid positive differential signal.
The third signal receiver function (SIG) provides a scaled analog output which is proportional to the differential voltage between XF1 and XF3. This output can be used for diagnostic purposes.
