PACUSB-U1/U2/U3  
Upstream USB Port Terminator  
Product Description  
Features  
One upstream USB port terminator, EMI filter and  
The PACUSB-U1, PACUSB-U2, and PACUSB-U3 are  
single-channel USB upstream-port termination net-  
works.  
transient overvoltage protector in a single surface-  
mount package  
Compact SC70 or SOT23 package saves board  
space and lowers manufacturing costs compared  
to discrete solutions  
ESD protection to 30kV contact discharge per  
MIL-STD-883D, method 3015  
ESD protection to 15kV contact discharge per  
IEC 61000-4-2 international standard  
Lead-free version available  
The PACUSB-U1/U2/U3 integrate EMI/RFI filter com-  
ponents R1 and C1, as recommended by the USB  
specification. Because these are upstream USB  
devices, they are terminated with a single 1.5kΩpull-up  
resistor to V (R2).  
3.3  
There are three options for the value of the series  
resistor R1:  
For PACUSB-U1, R1=15Ω  
For PACUSB-U2, R1=33Ω  
For PACUSB-U3, R1=22Ω  
Applications  
This series resistance plus the USB driver output resis-  
tance must be close to the USB cable’s characteristic  
impedance of 45Ω (90Ω balanced) to minimize trans-  
mission line reflections.  
ESD protection and termination of USB port  
All USB peripherals (PC printers, scanners,  
zip drives, etc.)  
PDAs / handheld PCs  
Digital cameras  
Wireless Handets  
MP3 Players  
Cable Modems  
In addition, these parts provide a very high level of pro-  
tection for sensitive electronic components that may be  
subjected to electrostatic discharge (ESD). The input  
and output pins are designed and characterized to dis-  
sipate ESD strikes of 15kV safely, a level well beyond  
the maximum requirements of the IEC 61000-4-2 inter-  
national standard.  
Using the MIL-STD-883D (Method 3015) specification  
for Human Body Model (HBM) ESD, all pins are pro-  
tected for contact discharges to greater than 30kV.  
The PACUSB-U1/U2/U3 is housed in either a 6-pin  
SC70 or 6-pin SOT23 package and is available with  
optional lead-free finishing.
