For theLogiCORE IPJESD204, in theGUI it only allows 1, 2.5, 3.125, and 6.25 GBit/s and reference clocks 1/10 or 1/20 of the line rate.
Is it possible to use the IP for different line rates and reference clocks?
The LogiCORE IP JESD204 v1.1 core should work at any line rate from 1G to 3.125 (6.25G in B).In the LogiCORE IP JESD204 v1.1User Guide (UG774), Table 6-1 states the following:
"Other reference clock options may be available but the GTX transceiver parameter settings require to be generated using the transceiver wizard."
However, manual generation of the GTX wrapper using the GTX Wizard is required for speeds not included on the JESD204 GUI. A coarse methodology would be as follows:
