KSZ8999I Frequently Asked Questions (FAQ)
-
The recommended PCB layout for the KSZ8999I involves placing the device near the RJ-45 connector, using a solid ground plane, and keeping the analog and digital signal traces separate to minimize noise and EMI.
-
The KSZ8999I can be configured for half-duplex or full-duplex operation by setting the appropriate registers. For half-duplex, set the HDX pin high and the FDX pin low. For full-duplex, set the HDX pin low and the FDX pin high.
-
The KSZ8999I supports cable lengths up to 100 meters, as specified in the IEEE 802.3u standard.
-
The KSZ8999I has a built-in power management feature that can be controlled through the PMEDEN pin. By setting this pin high, the device enters a low-power mode, reducing power consumption.
-
The KSZ8999I has a maximum junction temperature of 150°C. To ensure reliable operation, the device should be mounted on a PCB with a thermal pad and heat sink, and the ambient temperature should be kept below 70°C.
