 The FE1.1 is a highly integrated, high quality, high performance, low power consumption, yet low cost solution for USB 2.0 High Speed 4-Port Hub. It adopts Multiple Transaction Translator (MTT) architecture to explore the maximum possible throughput. Six, instead of two, non-periodic transaction buffers are used to minimize potential traffic jamming. The whole design is based on statemachine-control to reduce the response delay time; no micro controller is used in this chip.（点击即可咨询芯片详细信息）

FE1.1’s Features:

1.Fully compliant with Universal Serial Bus Specification Revision 2.0 (USB 2.0);

- Upstream facing port supports High- Speed (480MHz) and FullSpeed (12MHz) modes;

- 4 downstream facing ports support High-Speed (480MHz), Full-Speed (12MHz), and Low-Speed (1.5MHz) modes;

2.  Integrated USB 2.0 Transceivers;

3.  Integrated upstream 1.5KΩ pull-up, downstream 15KΩ pull-down, and serial resisters;

4.  Integrated 5V to 3.3V and 1.8V regulator.

5.  Integrated Power-On-Reset circuit;

6.  Integrated 12MHz Oscillator with feedback resister, and crystal load capacitance;
