6.3. Configuration Pin Differences from Previous Device Families

Intel Agilex configuration pin behavior is different from earlier device families. Knowing about these differences and how these
pins behave can help you understand and debug configuration issues.

An external source you can supply to increase the configuration throughput to 250 MHz.
Using an external clock source Transceivers, the HPS, PCIe, and the High Bandwidth Memory
(HBM2) require you this external clock.

Refer to Setting Configuration Clock Source for instructions on setting the clock source and
frequency in the Intel Quartus Prime Pro Edition software.
No dedicated location. Now called
SEU_ERROR
No single dedicated pin location. No longer Open Drain. External pull-up Is not mandatory.
x8 mode has a dedicated clock input on
modes, use AVST_CLK.
AVST_CLK and AVSTx8_CLK must be continuous and cannot pause during configuration.
When using the internal oscillator in AS mode, the
based on selection. If you provide a 25 MHz, 100 MHz or 125 MHz clock to the
AS_CLK
pin, the can run up to 133 MHz.
OSC_CLK_1 AS_CLK
No longer Open Drain.
After the SDM samples this pin functions as per the configuration mode selected. Do
