FE2.1
Overview
The FE2.1 is a highly integrated, high quality, high performance, low power consumption, yet low overall cost solution for USB 2.0 High Speed 7-Port Hub. It adopts Multiple Transaction Translator (MTT) architecture to explore the maximum possible throughput.
- Low power consumption □ 155 mA when seven downstream facing ports enabled in High-Speed mode; □ 66 mA when one downstream facing port enabled in High-Speed mode;
- Fully compliant with Universal Serial Bus Specification Revision 2.0 (USB 2.0); □ Upstream facing port supports HighSpeed (480MHz) and Full-Speed (12MHz) modes; □ 7 downstream facing ports support High-Speed (480MHz), Full-Speed (12MHz), and Low-Speed (1.5MHz) modes;
- Integrated USB 2.0 Transceivers;
- Integrated upstream 1.5KΩ pull-up, downstream 15KΩ pull-down, and serial resisters;
- Integrated 5V to 3.3V and 1.8V regulator.
- Integrated Power-On-Reset circuit;
- Integrated 12MHz Oscillator with feedback resister and crystal load capacitor;
- Integrated 12MHz-to-480MHz Phase Lock Loop (PLL);
- Multiple Transa
