Can you tell us, please, at least which chipset from MAXIM it is?<br>
Thanks<br>

Hi CD930,<br>
Sure dont release the PCB, but you could give us suggestions on
improving the RONJA design to 100 Mbps.<br>
You could point us in the right direction, like the modulation
technique to use, coding technique, or LED used ,or lasers, other
pitfalls you encountered ?<br>
Would you like to support a "free" cause ?<br>
<br>
Regards,<br>
Deepak<br>

Vladimir.<br>
Sorry, this development was for one firm from our city.<br>
I must not publish circuit PCB :(<br>
But....some ideas i am here publish along the years.<br>
<br>
In future looking on 1Gpbs..... avalanche photodiode with 200V dc :)))<br>
roung again toy gadget.<br>
