2.6.2. OSC_CLK_1 Clock Input
OSC_CLK_1 Requirements
When you drive
OSC_CLK_1
input clock with an external clock source and enable
OSC_CLK_1
in the Intel Quartus Prime
software, the device loads the majority of the configuration bitstream at 250 MHz. Intel Agilex devices include an internal
oscillator in addition to
OSC_CLK_1
which runs the configuration process at a frequency between 170-230 MHz. Intel Agilex
devices always use this internal oscillator to load the first section of the bitstream, approximately 200 kilobyte (KB). The SDM
can use either clock source for the remainder of device configuration. If you use the internal oscillator, you can leave the
OSC_CLK_1
unconnected.
