A 4-layer PCB with a solid ground plane and a separate power plane is recommended. Keep the analog and digital sections separate, and use a common mode filter to reduce EMI.
The RTL8305S is a highly configurable device. Use the RTL8305S configuration registers to set the desired protocol, speed, and duplex mode. Refer to the datasheet for register addresses and bit definitions.
The RTL8305S supports cable lengths up to 100 meters for 10/100Mbps and up to 80 meters for 1000Mbps, assuming Category 5e or higher cabling.
Use a logic analyzer or oscilloscope to monitor the RTL8305S's signal lines. Check the datasheet for troubleshooting guidelines and error detection mechanisms. Consult Realtek's application notes and FAQs for additional guidance.
Yes, the RTL8305S is rated for industrial temperature range operation. However, ensure that your PCB design and components can also withstand the same temperature range.
