Ethernet single chip things. (sound, data, ...)

[Ian Stirling]

I'd like to find a simple single chip, much like the USB-fifo chips
that are available, but on 100mbit ethernet.
Ideally, this would be able to do little more than listen for packets on
its address, and pass them to a FIFO for use locally.
It'd be nice if this could do DHCP to discover its IP address.
Even more ideal would be if it had an A/D to do 16 bit stereo sound.

I assume such doesn't exist.
What's the closest that's out there?

Not quite what you're looking for, but might be of interest -

Basically, cheap(ish) easily programmable low power multi-speaker
sound throughout the house.
There is the option of a hundred wires and soundcards/mixers, but
that gets bulky.

Thanks, will have a browse.

NetARMs (for easy development)...
Samsung's got processors with integrated MAC (and maybe PHY) also...
And there's probably lots of others. Google is your friend!

I take it you already have a LAN?

In case it needs extending: there's a review of MicroLink dLAN Audio in
Elektor this month. It does audio and ethernet over the mains wiring:

So, your CODEC is 1Mbps per audio channel? Good grief.

My point was, I think your math is off. 10Mb Ethernet could probably
handle 100 parallel channels of uncompressed audio...

uncompressed 44.1khz 16 bit stereo requires 1.4mbps. 10mb ethernet
could have a hard time carying 100 such streams.
