Reset Circuit
The reset circuit in Figure is recommended for powering up the KSZ8873MLL/FLL/RLL if reset is triggered only by the
power supply.
Figure 33. Recommended Reset Circuit
The reset circuit in Figure 34 is recommended for applications where reset is driven by another device (e.g., CPU, FPGA,
etc),. At power-on-reset, R, C and D1 provide the necessary ramp rise time to reset the KSZ8873MLL/FLL/RLL device.
The RST_OUT_n from CPU/FPGA provides the warm reset after power up.
