Reset Circuit
The following reset circuit is recommended for powering up the KSZ8041NL if reset is triggered by the power supply.
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 KSZ8041NL device. The RST_OUT_n
from CPU/FPGA provides the warm reset after power up.
