Matt 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...

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.

All of our new products going forward will require UHD, like DBSRX2, TVRX2, USRP N200, USRP N210, USRP E100, USRP E110. Matt
