Figure 32. Recommended Reset Circuit
The reset circuit in Figure 33 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
KSZ8893MQL/MBL device. The RST_OUT_n from CPU/FPGA provides the warm reset after power up.
