FE2.1 USB 2.0 HIGH SPEED 7-PORT HUB CONTROLLER

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. 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.

To guarantee high quality, the whole chip is covered by Test Scan Chain – include even 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 in the packaging and testing stages as well.

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.
