I know for a commercial product this would be considered a hack, but why
not
use the new 36 bit SRAM and ignore the extra bits?
or conversely use the new chip and create a riser card for it?
just a thought…

Hello:
Why is the USRP2 is going End-Of-Life (EOL) in March 2011? My
understanding is that one of the parts will soon become unavailable.
Which part is it?
The SRAM
I’m just curious, but wouldn’t it have been easier to just design
around the obsoleted part, or find a drop-in replacement, rather than
design an all-new USRP N210?
If there was a drop in replacement, we’d be using it. The replacement
part is 36 bits wide instead of 18, which necessitates an FPGA with more
pins.
That said, the N210 looks really nice. Will it support the raw
Ethernet interface currently used in the USRP2, or will it require
the new UHD interface?
It requires the UHD. All of our new products going forward will require
UHD, like DBSRX2, TVRX2, USRP N200, USRP N210, USRP E100, USRP E110.
