SN65HVD61

SLLS770A – JANUARY 2007 – REVISED FEBRUARY 2007

ControlNet™ TRANSCEIVER

The third signal receiver function (SIG) provides a

scaled analog output which is proportional to the

• Compatible With the ControlNet Standard

differential voltage between XF1 and XF3. This

• I/O Operates From 2.5-V to 5-V Supply

output can be used for diagnostic purposes.

• Receiver thresholds within –120mV to 120mV

FUNCTIONAL DIAGRAM

• Receiver hysteresis >50mV

• Low Power Standby Mode

• Thermal Shutdown Protection

• Power-Up/Down Glitch-free Bus Inputs and

Outputs

• Short-Circuit Protection on Outputs

• RoHS Compliant

• ControlNet Vendor ID 806

• Industrial Networks

• Programmable Controllers

• Industrial Drives

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.
