Yes, the USRP2 only has one DDC in the FPGA code.

I guess I was just curious why there is only one DDC in the FPGA, and if
it's possible in future that more than one will be made available.
It wouldn't be hard at all to put a second one in there, along with a
second DUC. Everything is set up to hold it, and there is enough space.
We just haven't had a need yet, since the USRP2 only holds one
daughterboard. If, however, you want to RX or transmit 2 different
signals on the same daughterboard, or are using a BasicRX/TX with dual
independent real signals at IF, then it would make sense.
