The USB repeater controller chip supporting one upstream and one downstream ports. The USB repeater controller connects to an upstream hub or Host/Root Hub or another repeater via upstream port and the downstream port connect to external downstream USB devices. The USB repeater controller re-transmits the USB differential signal between upstream port and downstream port in both directions . The USB repeater controller supports the 12 Mb/s full-speed as well as 1.5 Mb/s low-speed USB transitions .
