2.6. Configuration Clocks
2.6.1. OSC_CLK_1 Clock Input
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 Stratix 10 devices include an internal
oscillator in addition to OSC_CLK_1 which run the configuration process at a frequency
between 170-230 MHz. Intel Stratix 10 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, can you leave the OSC_CLK_1 unconnected.
Note: Device configuration may fail under the following conditions when you select the
OSC_CLK_1 as the clock source for configuration:
•
You fail to drive the OSC_CLK_1 pin.
•
You drive the OSC_CLK_1 pin at an incorrect frequency. Select one of the following
input reference clock frequencies to drive the OSC_CLK_1 pin:
— 25
— 100
— 125
The Intel Stratix 10 device multiplies the OSC_CLK_1 source clock frequency to
generate a 250 MHz clock for configuration. Using an OSC_CLK_1 source enables the
fastest possible configuration. Refer to Setting Configuration Clock Source for
instructions on completing this task.
