Yes, there is a bus NOC100 with a dedicated clock tree in the HW (with 3 muxes and one divider), which makes possible to take different PLL as a source then WCORE have, divide the rate from it and even switch for a while to alternative stable PLL (on the 2nd mux to SPLL (after a divider)) to wait for main PLL rate change stability delay. Max rate is limited to 100MHz for this NOC100 bus.
