Any progress on this? I’d love to use a 10 MHz GPS disciplined oscillator to make a 10 MHz RF SYS REFCLK or SYSREF, along with a nice round sampling rate.
With the LMK, is it possible to use a 10 MHz Ext. Ref. Clk if it’s plugged in, and the 160MHz VCXO OSC IN otherwise? Or do you need to explicitly load one or the other configuration?
As a starting point, is there a repository for the original .tcs files that can be opened in the TICS Pro for RFSoC 4x2’s? For example, the .tcs files that generated LMK04828_500.0.txt and LMX2594_500.0.txt in RFSoC-MTS/boards/RFSoC4x2/xrfclk at main · Xilinx/RFSoC-MTS · GitHub ?
To integrate with and compare to our other astronomy and instrumentation, round numbers and powers of 2 are nice. I’d love 4 GSPS or 5 GSPS. Even the Gen1 4096 MSPS makes nice FFT spectral bins that are 1 MHz wide and a RAM capture that is a microsecond long (or twice these or half of these or whatever). The obsession with 7.68, 122.88, 245.76, 491.52, and 3932.16 MHz seems to stem from the 300 Hz/baud Bell 103 modem from 1962. This factor of 3 seems to have seeped into all comms rates ever since.
Thanks,
Jason
