What is the default converter rate (clock frequency of the DAC/DAC)

For USRP N210
I am reading benchmark_tx/rx.py,
There is no option for me to input the converter rate, I is using the
default one.
Does anyone know what is the default value?
Thank you

I believe the N210 converters are fixed at 100 MHz clock. If you choose
16 bit words, then a minimum decimation of 4 takes place within the
FPGA. That yields 25 Msps (complex samples). If you choose 8 bit
samples you can go to 50 Msps.
