4-Port USB 2.0 HUB Controller IC FE1.1 (QFP48)

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.
