LON® technology makes possible a new generation of
smart, low-cost products that communicate with one
another and that can be linked together to serve applications in consumer electronics, factory automation, vehicle
controls, commercial building controls, home automation,
and other industries. The PE-65848 and PE-65948
transformers are designed specifically for use with
Echelon’s NEURON® 3120TM and NEURON® 3150TM chips in
1.25 Mbps, twisted pair bus applications. The transformers
provide DC isolation and common mode noise rejection.
Their characteristics have been optimized to assure the
proper pulse waveform is transmitted onto the twisted pair
cable when used in conjunction with the recommended
circuitry. The transformers provide 1500 Vrms high voltage isolation for one minute, but are not intended for use
as a hazardous voltage safety barrier. Order PE-65848T
for optional tape and reel packaging (250 pieces per reel).
When using PE-65948, centertaps can be created by connecting winding ends together on the PCB.
