1.0 Introduction
1.1 Description
AU6254 is a fully compliant with the USB 2.0 hub specification and is designed to work with USB host as a high-speed hub. Its built-in TT (Transaction Translator) allows system to benefit combinational performance under the unbalanced traffic condition. AU6254 supports four USB downstream ports and one upstream port. Each downstream port could be a device of high-speed, full-speed or low-speed traffic, while the upstream port supports both high-speed and full-speed traffic. For each downstream port it has individual power switch control built-in as over-current sensing control. In addition to the application as a stand-alone hub, AU6254 is also very suitable for using in notebook and motherboard design to provide additional USB port. All these product advantages should be attributed to its compliance to standards, performance and low power consumption.

1.2 Features
* * * * * * * * * * * * * * * Fully compliant with USB Hub Specification version 2.0 and is also backward compatible with USB Hub specification 1.1. Single chip USB 2.0 hub controller. Supports four bus-powered/self-powered downstream ports. Supports automatic switching between bus- and self-powered modes. Cost effective design using one transaction translator for all downstream ports. Two-color LED controls available for each downstream port to indicate the status of each device port. Extra low power consumption. On chip internal pull-up and meets USB bus power regain emend pull down resistors for all data line. Built-in USB 2.0 transceiver. Supports individual and gang modes of power management. Built-in power switch control for over current sensing control. Built-in 1.8V regulator for core logic. Embedded in PLL (Phase Lock Loop) circuit for 12MHz operation precision Supports external EEPROM interface for customized PID and VID Available in two different form factors: 48-pin LQFP package and 64-pin LQFP package.

3.0 Pin Assignment
Depending on the occasion of various applications, there are two different form factors of AU6254 is available to choose from. One is in 48-pin LQFP package, while the other is in 64-pin LQFP package. With more control pins available, 64-pin package offers extra features, such as individual powered, in additional to the features found in 48-pin package. The figure printed below shows the signal names of 48-pin and the table in the page after describes each pin in detail. Figure 3.1 Pin Assignment Diagram

5.5 Crystal Oscillator Circuit Setup for Characterization
The following setup was used to measure the open loop voltage gain for crystal oscillator circuits. The feedback resistor serves to bias the circuit at its quiescent operating point and the AC coupling capacitor, Cs, is much larger than C1 and C2.
