I’ve made a few things now using a RJ45 jack and a separate pulse transformer. Post as a guest Name. Email Required, but never shown. Now that it has become clear that you are using a Lantronix module , as opposed to a PHY chip , the easiest solution is to find a MagJack that has both CT pins broken out, for example: Connect the CT pin to the system power e. After all, they broke out the pins separately, presumably so they can swap phy’s on their modules while staying compatible with client’s hardware.

Now that it has become clear that you are using a Lantronix moduleas opposed to a PHY chipthe easiest solution is to find a MagJack that has both CT pins broken out, for example: Here’s a sample magjackk. In that case, I’d recommend that you either find a connector with both of those pins broken out, or contact Lantronix and ask them what to do.
To make the design smaller i’m looking to use a magjak or a RJ45 connector with the pulse transformer built in. We undertake no obligation to update or revise any forward looking statement.
Armandas 6, 1 23 I’ve no experience with this particular module and the documentation does not say much about those pins. The jack has the center tap pins tied together to a single pin.

Armandas As suggested by a comment i selected a mag jack that had both networo taps broken out individually.

On a different connector, you may find two CT pins, so you’ll need to use one cap for each pin. In light of the risks and uncertainties, there can be no assurance that any majack statement will in fact prove to be correct. Did you come to any solution?
For metwork information, contact Bel Magnetics at After all, they broke out the pins separately, presumably so they can swap phy’s on their modules while staying compatible with client’s hardware. Targeted applications include low profile devices, next generation servers and storage equipment, in addition to blade servers or network interface cards, laptop computers and maggjack cards.

I also mentioned in the comments that you could contact Lantronix support or see where those lines are connected on the module. The combination of profile and speed permits customers to put Netwotk ports in locations, not possible in previous versions.

Hans 6, 1 20 I would not risk such an issue and find another ethernet jack with separate CT pins, so you can support separate common mode levels for TX and RX. Home Questions Tags Users Unanswered.
