FE1.1 — USB 2.0 4-Port MTT Hub Controller

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.

MTT 架構

The chip adopts Multiple Transaction Translator (MTT) architecture to explore the maximum possible throughput. Six 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

品質保證

The whole chip is covered by Test Scan Chain – even on high-speed (480MHz) modules. Built-In-Self-Test mode exercises all high-, full-, and low-speed Analog Front End (AFE) components at the packaging and testing stages.

低功耗

Achieved by using 0.18μm technology and comprehensive power/clock control. Most part of the chip will not be clocked unless needed.
