1. Introduction
1.1 Description
AU9228 is a highly integrated single chip USB KVM controller offering users the
possibility of sharing keyboard, mouse and monitor among up to four PCs. Not like
traditional PS2 KVM devices, AU9228 uses USB as its upstream and downstream
interface to support its driver-free and plug-n-play features, which allow users to easily
install and use the KVM.
Typical application of AU9228 is under an environment, in which only one set of
monitor, keyboard and mouse is available. Applying such kind of devices in a
computing environment will not only result in a centralized control, but also reduce the
power and space consumption.
1.2 Features
ꢀFully USB v1.1 specification compliant
ꢀSupport USB bus power and device self power
ꢀSupport up to 4 PCs via 4 USB upstream ports
ꢀSupport USB downstream port 1 for USB keyboard
ꢀSupport USB downstream port 2 for USB mouse
ꢀSupport PS2 keyboard
ꢀSupport both “panel button” and “hot key” to switch among PCs
ꢀSupport “auto-scan” mode for users to monitor PCs easily
ꢀSupport audio beep when system switches
ꢀSupport upstream port selected LED indicators for each PC respectively
ꢀSupport phantom keyboard to let user does not need to configure BIOS to turn
on “No halt on error”
ꢀSupport 4 different sets of key sequence to switch among PCs (Please see the
key definition in the following)
ꢀRecalls “Caps Lock”, “Num Lock” and “Scroll Lock” keys’ status for each PC
automatically
ꢀOutput the monitor selection signals to the external video-switching circuits
ꢀSupport 8-bit MCU interface to provide control from external MCU
ꢀSupport serial MCU interface to provide control from external MCU
ꢀNo need to install device driver under Windows, Macintosh, Linux, FreeBSD
and Sun system

twice rapidly and then press “1”. If system receives “Scroll ++ Scroll” command only,
system will reset the buffer when it does not receive any input comes after within a
defined interval of time (say, 5 seconds).

6.4 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.

6.5 ESD Test Results
Test Description: ESD Testing was performed on a Zapmaster system using the
Human-Body –Model (HBM) and Machine-Model (MM), according to MIL_STD 883
and EIAJ IC_121 respectively.

6.6 Latch-Up Test Results
Test Description: Latch-Up testing was performed at room ambient using an
IMCS-4600 system which applies a stepped voltage to one pin per device with all
other pins open except Vdd and Vss which were biased to 5 Volts and ground
respectively.
Testing was started at 5.0 V (Positive) or 0 V(Negative), and the DUT was biased for
0.5 seconds.
If neither the PUT current supply nor the device current supply reached the predefined
limit (DUT=0 mA , Icc=100 mA), then the voltage was increased by 0.1 Volts and the
pin was tested again.
This procedure was recommended by the JEDEC JC-40.2 CMOS Logic
standardization committee.
