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.

Note 1: ESD applied to input/output/V3.3 pins with respect to GND, one at a time. Clamping voltage is measured at the opposite side  
of the EMI filter to the ESD pin (i.e., if ESD is applied to pin 1, then clamping voltage is measured at pin 6). Unused pins are  
open.

PACUSB-U1/U2/U3  
Application Information  
The PACUSB-U1/U2/U3 is targeted for upstream USB  
ports (peripherals). It provides series termination, EMI  
filtering, and ESD protection for the two USB data lines  
D+ and D-.  
Connections for Full Speed Operation  
Full Speed devices have the pull-up resistor (R2) con-  
nected to the D+ data line, as shown in Figure 1. Pin1  
is tied to the D+ line of the USB controller. Pin 6 is con-  
nected to the D+ line on the USB connector.  
The USB Specification revision 1.1 provides for two  
data rates:  
The Full Speed signaling bit rate at 12 Mbits per  
second, and  
Connections for Low Speed Operation  
Low Speed devices have the pull-up resistor (R2) con-  
nected to the D- data line, as shown in Figure 2. Pin 1  
is tied to the D- line of the USB controller; pin 6 is con-  
nected to the D- line on the USB connector.  
The Low Speed signaling bit rate at 1.5 Mbits per  
second.  
The speed is selected by connecting one of the data  
lines (D+ or D-) to a 3.3V supply voltage via a 1.5kΩ  
pull-up resistor (R2).
