Hi all looking for some help from everyone. Were getting ready to do our own custom daughterboards for the usrp n200. I have looked at the schematic and the two opamp ICs are easy enough to understand. But, there is some sort of programmable EPROM (24LC0258B) located on the rx daughterboard. I was wondering if someone could explain it's function and exactly what it does. Or at least let me know if it is proprietary and the info is not to be shared. Thank you all, Mike

To understand the d'boards, I recommend not only reading the schematics, but also the drivers. You'll find this kind of info there. M
