Hello all,



Bothhand has stopped the production of the FB2022.

After checking with Realtek, it seems -fortunately- there are no plans to
stop production of the RTL8019AS. But. we don't have an alternative for the
FB2022 yet.



Does anyone have a good alternative for this device?



Thanks for your help.



Best regards,



Johan van der Stoel

Herald,

Realtek will work with any Ethernet 1:1 transformer.
Can you consider reworking PCB for SMT trafo?
Most popular are like this one

Pulse H1260

And many many others.

Cheers
Peter.

FL1012 works nicely with the RTL8019AS

Hi!

You might also like to check with Würth as they expanded their product
range there recently. If you need a good contact, wait till next week,
when I am back in the office.

Best regards, Ulrich

The RTL8019AS won't use a 1:1 transformer.
It is something like 1:1,41 or so.
That's also the reason why you can't connect the RTL directly to
a switch.
With 1:1 you can just use coupling capacitors for onboard connections.

There had been many transformers on the market when NE2000 cards
had been popular.
Compatible transformers also had been used in many 10MBit/s Hubs
at this time.

A few compaible (also Pinwise) that comes to mind are:
YCL 20F001N
LANKom LF-161C
GROUP-TEK BTF-22
GTS FC-22

But I don't know if any of them is still on the market.
I've had a more complete list, but can't find it right now.
I stopped searching myself and just sourced Bothhand from Egnite.

I don't have samples for 10 MBit here, but Würth has a quite good
support and at least some SMT transformers for 10 MBit. They are called
WE-LAN xxx

Our contacts are:

Michael.Zey (at) we-online (dot) de
Norbert.Wieczorek (at) we-online (dot) de

Bye,

Ole
