Designing an Ethernet Switch

[GG]

Hi,

Need to design an Ethernet Switch (industrial temp) that can handle up
to 16 ports and am looking at companies, so far have Broadcom, Micrel
and Zarlink. Broadcom has a good device that will do the job however
I'm concerned with the support they can provide, how is Zarlink and
Micrel in terms of supporting their customers? Anybody used any of the
Micrel or Zarlink parts and what type support and how good are the
parts? Any other companies apart from the ones listed above?

Thanks for the help.

Well, if Broadcom does one that does the job in a way you can understand it
then you can rest assured that the rest of the lazy arsed barstards couldn't
be bothered so it's not as if their application engineers would be able to
sort it out for you. Ov course you can use this to your advantage whilst
dialling up BinBong LahLah and Po to drive their prices down but you might
have to have their application engineers come around and drink a few beers
wiv you.

Anyway.... and I'm not sure about this..... but don't you just stuff
something up a router using 192.168.1.2 thru 192.168.1.17 in some part of
the packet addressed to 192.168.1.1 in another part and it all gets
sorted?.... apart from that stuff about DHPC and MAC addresses but that is
cool as well?

Broadcom has a line of switches and a set of libraries (available with
a licensing agreement) that will drive them under a number of operating
systems. Their configuration interface is a little wacky, but the library
can hide that from you.

IC+ also make some Ethernet switch chips and I understand they
have a significant market share. I am only sort of familiar with their
5 port 10/100 chip, but they do have others and they are OK to talk to.

Not sure if they have 16-ports devices but you can have also a look at
Infineon : We've used their ADM6969 "Samurai" switches in a project without
any problem.

Need to design an Ethernet Switch ... how is Zarlink and
Micrel in terms of supporting their customers? Anybody used any of the

parts?

I've used the Micrel/Kendin parts (KS8993/5), though not over the full
industrial temp range. Support is practically non- existent once they
realise you aren't going to buy 10e6 units a month, but the parts are
cheap enough and easy to use. Follow the reference circuit reasonably
well, and they just work.

If you need the management port, there are small but really annoying
differences between the two parts that held the software up for a while,
but otherwise no real sweat.

My expericence with Broadcom is rather unpleasant (NDA, software support
almost inexistent, especially for Linux hey !!) I'd rather choose RealTek
for this kind of project, they have comprehensive solutions around
telecom and Ethernet technologies.

Thank for a pointer, their ADM6969G chip looks like what the doctor ordered
for my application ) 8 10/100 ports plus 1 gigabit port and full
documentation available without NDA or some other handicaps. And it is not
in one of those super-tiny BGA packages...

I'm having trouble finding the data sheets for the Infineon ADM6969G
chip, can someone please send me the link. Thanks.

Just go to Infineon site, then "Wired communication customer premises
equipment," then "Broadband CPE," then "more..." and here it it is in
"Switch"...
