USB HUB one expansion four SL2.1A, SL2.2S, FE.1.1S/USB to Ethernet (PHY) SR9900, RTL8152B

USB Hub, refers to a device that can expand one USB interface into multiple, and can use these interfaces at the same time. USB HUB can be divided into USB2.0 HUB, USB3.0 HUB and USB3.1 HUB according to the USB protocol. USB2.0 HUB supports USB2.0, the theoretical bandwidth is up to 480Mbps; USB3.0 HUB supports USB3.0, backward compatible with USB2.0/1.1, the theoretical bandwidth is up to 5Gbps; USB3.1 HUB supports USB3.1, backward compatible with USB3 .0/2.0/1.1, the theoretical bandwidth is up to 10Gbps. Hub is a hub that is often referred to. It uses a star topology to connect multiple USB interface devices.

USB Hub, can be connected to computer desk lamp, computer fan, MP3, U disk, voice recorder, digital camera, etc. It can expand one USB interface into multiple independent USB interfaces. USB to Ethernet is a highly integrated, ultra-low power, single-chip USB2.0 to 1000/100M Ethernet control circuit.

Adds low cost, small form factor, plug-and-play Fast Ethernet functionality to a wide range of applications including desktops, laptops, ultraportables, tablets, bays/port replicators/docks, game consoles , smart home and any embedded device with USB interface.

Internal integrated USB 2.0 transceiver, 1000/100M Ethernet module based on IEEE802.3 and IEEE802.3az-2010, and efficient memory control module. SR9900 is fully compatible with Microsoft's NDIS5, NDIS6 (IPv4, IPv6, TCP, UDP) Checksum feature. And supports IEEE802IP2 layer priority coding, and IEEE802.1Q virtual local network (VLAN).
