Clocking

VCO divider must be set properly so that the core VCO frequency is in the

range of 800–1800 MHz.

core_clk : csb_clk Ratio

VCO Divider1

1 Core VCO frequency = core frequency

× VCO divider. The VCO divider must be set properly so that the core VCO frequency

is in the range of 800–1800 MHz.
