Re: [Discuss-gnuradio] Clock rate change on x300

[Mitchell, Paul]

I’m fine using one of the supported rates.  That’s totally fine.  I would just like to know how to check the clock rate and swap between the two for experimentation purposes.  Is there a terminal string I can run in Linux to do this?

Hi Paul,

What rate do you want to adjust it to and for what purpose? The X300
supports a master clock rate of 200 MS/s and 184.32 MS/s. The built in
DSP can convert to an integer divisor sample rate of one of those two.
Adding support for another rate would require either a lot of software
work or implementing a rational resampler in the FPGA in which case you
would need a Vivado license.
