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 state-machine-control to reduce the response delay time; no micro controller is used in this chip.The whole chip is covered by Test Scan Chain – even on the high speed (480MHz) modules, so that all the logic components could be fully tested before shipping.

Special Build-In-Self-Test mode is designed to exercise all high, full, and low speed Analog Front End (AFE) components.Low power consumption is achieved by using 0.18μm technology and comprehensive power/clock control mechanism. Most part of the chip will not be clocked unless needed.

SPECIFICATIONS:

  1. Fully compliant with Universal Serial Bus
  2. Upstream facing port supports High-Speed (480MHz) and Full-Speed
  3. (12MHz) modes.
  4. 4-downstream facing ports support: High-Speed (480MHz), Full-Speed (12MHz), and Low-Speed (1.5MHz) Modes.
  5. Integrated USB 2.0 Transceivers;
  6. Integrated upstream 1.5KΩ pull-up,downstream 15KΩ pull-down, and serial resisters
  7. Integrated 5V to 3.3V and 1.8V regulator.
  8. Integrated Power-On-Reset circuit;
  9. Integrated 12MHz Oscillator with feedback resister, and crystal load capacitance;
  10. Integrated 12MHz-to-480MHz Phase Lock Loop (PLL);
  11. Multiple Transaction Translators (MTT) –One TT for each downstream port;
  12. Alternate Interface 0 for Single-TT, and Alternate Interface 1 for Multiple-TT;
  13. Each TT could handle 64 periodic,Start-Split transactions, 32 periodic
  14. Automatic self-power status monitoring.
