General Description
The FE1.1s 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 Single Transaction Translator (STT) architecture to be more cost effective. 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 – 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 on the packaging and testing stages as well.
Low power consumption is achieved by using 0.18ÎĽm technology and comprehensive power/clock control mechanism. Most part of the chip will not be clocked unless needed.
