Evaluation Board for the
5 kV rms Signal and
Power Isolated RS-485 Transceivers with ±15 kV ESD Protection
FEATURES
5 kV rms power and signal isolated RS-485/RS-422 transceiver
Convenient connections for power and signal through screw
terminal blocks
Configurable as half duplex or full duplex
5 V or 3.3 V operation
Easily configurable through jumper connections
Test points for measuring all signals
Layout optimized for emissions according to the
The evaluation board is easily configured through jumper
connections. The board can be used in half-duplex or full-
duplex configurations and has a 120 Ω termination resistor
fitted on the receiver input. The evaluation board can be used
with either the
16 Mbps part or the
500 kbps part. The driver and receiver are enabled and disabled
by jumper connections. Test points are included on the power
and signal lines on both sides of the isolation barrier.
RADIATED EMISSIONS
The
evaluation board is designed to
reduce emissions generated by the high frequency switching
elements used by the
isoPower®
technology to transfer power
through its transformer. The layout of the evaluation board
was generated using the guidelines provided in the
Recommendations for Control of Radiated
Emissions with
isoPower
Devices.
