To clarify, you don't have to program the FPGA to *set* the high clock
rates, but to make any use of them you have to.

Hi all,
Does this apply to the B210 too?
That is correct, handling data at a rate much higher than 8 MS/s will
require moving DSP into the FPGA. UHD comes with a variety of example
RFNoC blocks. The fosphor block for instance produces
of the E310.
Thanks in advanced!

Hello Laura,
The ADCs and DACs do support running at 61.44 MS/s. However the ARM processor
is not able to handle data traffic at that rate so some of the processing must

Hello Laura,
The ADCs and DACs do support running at 61.44 MS/s. However the ARM
processor is not able to handle data traffic at that rate so some of the
processing must be done in the FPGA. Depending on the application about 10
MS/s is an achievable rate.
Both 12 MS/s and 8 MS/s are not integer
Oh, in addition -- there's a single "radio clock" which is picked based on
the transmit and receive sample rates. This means that, while you have
nearly infinite flexibility as to the sample rate used for just RX or just
TX, when you are using both simultaneously their rates will be tied to each
8MS/s is about what you can stream *through the host processor* on E310.
Full-rate streaming is supported just fine through the FPGA fabric. If you
need to do faster rate streaming on the E310, you need to do the processing
in the FPGA.

Happy Friday,
What is the max sample rate for the Ettus e310?
When I ssh in and perform the benchmark_test, I get the following:
$/usr/lib/uhd/examples/benchmark_rate --rx_rate 12e6 --tx_rate 12e6
.
. [other stuff here]
.
UHD Warning:
The hardware does not support the requested TX
