DESCRIPTION
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.
