GL850 datasheet下载

GL850 is a 4-port standard Universal Serial Bus (USB) hub controller complies with Universal Serial Bus Specification Revision 2.0. GL850 can be connected to an USB1.1 host/hub or an USB2.0 host/hub. When GL850 is connected to an USB1.1 host/hub, it works just like an USB1.1 hub; the upstream port will operate in full-speed (FS) and the downstream port can operate in full-speed or low-speed (LS). When GL850 is connected to an USB2.0 host/hub, it works as an USB2.0 hub; the upstream port will operate in high-speed (HS) and the downstream port can operate in high-speed, full-speed, or low-speed. The bandwidths of high speed, full speed, and low speed are 480 Mbps, 12 Mbps, and 1.5 Mbps respectively.
