The circuit below is a guideline for interconnecting PCA’s EPE6367G with transceiver chip as a reference controller.

Further details of system design, such as chip pin-out, etc. can be obtained from the specific chip manufacturer.

Typical insertion loss of the isolation transformer/filter is 0.7dB. This parameter covers the entire spectrum of the encoded

signals in 10 Base-T protocols.

The phantom resistors shown around the RJ45 connector have been known to suppress unwanted radiation that unused

wires pick up from the immediate environment. Their placement and use are to be considered carefully before a design is

finalized.

It is recommended that there be a neat separation of ground planes in the layout. It is generally accepted practice to limit

the plane off at least 0.08 inches away from the chip side pins of EPE6367G. There need not be any ground plane beyond

this point.

For best results, PCB designer should design the outgoing traces preferably to be 50

Ω, balanced and well coupled to

achieve minimum radiation from these traces.
