Reset Circuit Diagram
Micrel recommends the following discrete reset circuit, as shown in Figure 26, when powering up the KS8895MQ
device. For the application where the reset circuit signal comes from another device (e.g., CPU, FPGA, etc), Micrel
recommends the reset circuit, as shown in Figure 27.
Figure 26. Recommended Reset Circuit
Figure 27. Recommended Circuit for Interfacing with CPU/FPGA Reset
At POR, 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.
