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.
