175f8b8ccc drtio/gth_ultrascale: generate multiplied RTIO clock from BUFG_GT (#792) 2019-01-03 20:14:18 +08:00
77126ce5b3 kasli: use hwrev 1.1 by default for DRTIO examples 2019-01-02 23:04:20 +08:00
ab9ca0ee0a kasli: use 150MHz for DRTIO by default (Sayma compatibility) 2019-01-02 23:03:57 +08:00
cc58318500 siphaser: autocalibrate skew using RX synchronizer
* removes the hardcoded, (poorly) manually determined skew value
* does not need si5324_clkout_fabric anymore (broken on Sayma RTM due to wrong IO voltage)

ba4bf6e59b kasli: don't pass rtio pll feedback through bufg
UG472: "The MMCM performance increases because the
feedback clock is not subjected to noise on the core supply since it
never passes through a block powered by this supply."
