FE1.1S
USB 2.0 HIGH SPEED 4-PORT HUB CONTROLLER
_______________________Data Sheet_______________________
INTRODUCTION
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
0.1m technology and comprehensive
power/clock control mechanism. Most part of the
chip will not be clocked unless needed.
FEATURES
Fully compliant with Universal Serial Bus
Specification Revision 2.0 (USB 2.0);
Upstream facing port supports High-
Speed (480MHz) and Full-Speed
(12MHz) modes;
4 downstream facing ports support
High-Speed (480MHz), Full-Speed
(12MHz), and Low-Speed (1.5MHz)
modes;
Integrated USB 2.0 Transceivers;
Integrated upstream 1.5KΩ pull-up,
downstream 15KΩ pull-down, and serial
resisters;
Integrated 5V to 3.3V and 1.8V regulator.
Integrated Power-On-Reset circuit;
Integrated 12MHz Oscillator with feedback
resister, and crystal load capacitance;
Integrated 12MHz-to-480MHz Phase Lock
Loop (PLL);
Single Transaction Translator (STT) –
One TT for all downstream ports;
The TT could handle 64 periodic Start-
Split transactions, 32 periodic
Complete-Split transactions, and 6
none-periodic transactions;
Automatic self-power status monitoring;
Automatic re-enumeration when Self-
