Figure 17. Recommended Reset Circuit
The following reset circuit is recommended for applications where reset is driven by another device (e.g., CPU or FPGA).
At power-on-reset, R, C and D1 provide the necessary ramp rise time to reset the KSZ8041NLJ device. The RST_OUT_n
from CPU/FPGA provides the warm reset after power up.
