SR9900USB to network port

• This project is used to verify the solution verification board design of Lichuang Mall Ethernet chip/SR9900 ( product number: C403645 )
• This project can also be used to verify the verification board design of the Lichuang Mall Ethernet chip/RTL8152B-VB-CG ( product number: C361050 ) solution
• This project is  a sample project for the Solicitation Order for Lichuang EDA open source hardware platform  solution verification module .

In order to reduce the thickness of my current laptop, the Ethernet interface on it has a spring-loaded cover. The network cable often gets stuck, and I have to open the cover while unplugging the network cable. If this continues, one day I will break it.

SR9900 and RTL8152B are two usb2.0 to network port chips with basically the same pins. The speed of usb2.0 can theoretically reach more than 400mbps, which is completely sufficient for the mobile ultra-fast (ji) 200M broadband at my home. The method of using USB to connect the network cable is great. .

Datashit said that SR9900 needs to use the SR9900Efuse mass production tool to mass-produce the MAC address and SPI program-Windows system driver of the SR9900 network card device. Find the information in the Lichuang community and upload it here.

I saw that there are only a few pieces of SR9900 left in Lichuang Mall , and the one used is RTL8152B .

Now I want to see if it can be combined with the one-to-four USB 2.0 HUB chip SL2.1A from Lichuang Mall .
