Reset Circuit
Figure 15 shows a reset circuit recommended for powering up the KSZ8051MLL if reset is triggered by the power supply.
Figure 15. Recommended Reset Circuit
Figure 16 represents a reset circuit 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 KSZ8051MLL device. The
RST_OUT_n from CPU/FPGA provides the warm reset after power up.
