What is the pull-up resistor guideline for the DDR4 alert_n signal? - What is the pull-up resistor guideline for the DDR4 alert_n signal?
Description The recommendation is to start with a 10k ohm pull-up resistor to 1.2V for the DDR4 alert_n signal, and then the resistor can be adjusted to a different value as long as it meets the FPGA I/O buffer VIL and VIH specifications (refer to the FPGA device datasheet under the I/O Standards specification). Perform a board signal integrity simulation to verify the optimal setting.
