Description

The FE1.1s is a highly integrated, high quality, and high performance solution for USB 2.0 4-port hub. With its tiny footprint and extremely low power consumption, it is the best choice for embedded application as well as standalone hub.

The high quality of FE1.1s is guaranteed by Design- For-Testing with comprehensive scan chains and Built-In-Self-Test modes which could exercise all High, Full, and Low Speed analog front end (AFE) components on the packaging and testing stages.

FE1.1s could be optionally configured to support Charging Downstream Ports as defined by USB-IF Battery Charging Specification. With this feature enabled, an USB hub could be easily transformed into a charging station – USB Charging Hub for Universal Charging Solution compliant battery based portable devices.
