3.2.8. AS_CLK
The Intel Agilex® 7 device drives AS_CLK to the serial flash device. An internal oscillator or the external clock that drives the OSC_CLK_1 pin generates AS_CLK. Using an external clock source allows the AS_CLK to run at a higher frequency. If you provide a 25 MHz, 100 MHz, or 125 MHz clock to the OSC_CLK_1 pin, the AS_CLK can run up to 166 MHz.
Set the maximum required frequency for the AS_CLK pin in the Intel® Quartus® Prime software as described in Active Serial Configuration Software Settings. The AS_CLK pin runs at or below your selected frequency.
Configuration Clock Source | AS_CLK Frequency (MHz) |
---|---|
Internal oscillator | 25 58 77 115 |
OSC_CLK_1 (25/100/125 MHz) | 25 50 71.5 100 125 166 |
Note: The configuration fails if the firmware receives bitstream with an invalid AS_CLK setting. For firmware in Intel® Quartus® Prime software version before 21.1, if AS_CLK is set incorrectly, the firmware defaults the AS_CLK frequency to 50 MHz to complete the AS x4 configuration.
