For the application where the reset circuit signal comes from another device (e.g., CPU, FPGA, etc), the following reset circuit
is recommended.
VCC
R 10K
D1
KSZ8001
CPU/FPGA
RST#
RST_OUT_n
D2
C 10uF
D1, D2: 1N4148
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
from CPU/FPGA provides warm reset after power up. It is also recommend to power up VDD core voltage earlier
than VDDIO voltage. At worst case, the both VDD core and VDDIO voltages should come up at the same time.
