Designing an Ethernet Switch

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. Yours, Robert Lacoste

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"...
