Statement of Shuttle Mainboard via the EMI Test
Shuttle mainboards have been via the EMI test in terms of series of regulations: EN55022/
CISPR22/AS/NZS3548 Class B, EN55024 (1998/AS/NZS), EN4252.1 (1994), EN61000, ANSI
C63.4 (1992), CFR47 Part 15 Subpart B, and CNS13438 (1997). The items tested are illus-
trated as follows:
(A) Voltage: AC 110V/60HZ & AC 230V/50HZ
(B) Tested Product Information:
Product Name: PC Mainboard
Status: Sample
Model Name: AK32E
S/N: N/A
CPU:
External Frequency: 133 MHz
AMD Athlon /1600+/1700+/1800+/1900+/2000+/2100+/2200+/2400+/
2600+, 1.00/1.13/1.20/1.33/1.40 GHz
External Frequency: 100 MHz
AMD Athlon 750/800/850/900/950 MHz, 1.0/1.10/1.20/1.30/1.40 GHz
AMD Duron 700/750/800/850/900/950 MHz, 1.0/1.1/1.2/1.3 GHz
Keyboard Port: one port with 6 pins
Mouse Port: one port with 6 pins
USB 2.0 Port: two ports with 4 pins respectively
Parallel Port: one port with 25 pins
Serial Port: two ports with 9 pins respectively
MIDI/Game Port: one port with 15 pins
Line-Out & Line-In & Mic-In Ports: one port for each
DDR Memory: 256 MB *2
All CPUs have completely been tested, and values offered by the worst EMI combination of
CPU external frequency are listed as follows:
(C) Remedy for the Tested Product & Its EMI Interference:
Remedy: N/A
EMI Interference:
Crystal: 32.768 KHz(X1)/14.318 MHz(X2)/24.576 MHz(X3)
Clock Generator: U10
(D) Difference between AK32E and AK32:
To discriminate AK32E from AK32 lies in the extent that chips in AK32E support USB 2.0, and
the combination for testing is based on AK32E.
