KSZ8895MQ/RQ/FMQ
Reset Circuit Diagram
Micrel recommends the following discrete reset circuit as shown in Figure 22 when powering up the KS8895MQ device.
For the application where the reset circuit signal comes from another device (e.g., CPU, FPGA, etc), we recommend
the reset circuit as shown in Figure 23.
Figure 33. Recommended Reset Circuit
Figure 34. Recommended Circuit for Interfacing with CPU/FPGA Reset
At power-on-reset, R, C, and D1 provide the necessary ramp rise time to reset the Micrel device. The reset out
RST_OUT_n from CPU/FPGA provides the warm reset after power up.
