Upstream USB Port Terminator  
PACUSB-U1/U2/U3  
Features  
Product Description  
One upstream USB port terminator, EMI filter and  
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, PACUSB-U2, and PACUSB-U3  
are single-channel USB upstream-port termination  
networks.  
The PACUSB-U1/U2/U3 integrate EMI/RFI filter  
components R1 and C1, as recommended by the  
USB specification. Because these are upstream USB  
devices, they are terminated with a single 1.5kW pull-  
up resistor to V3.3 (R2).  
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  
This series resistance plus the USB driver output  
resistance must be close to the USB cable’s  
characteristic impedance of 45Ω (90Ω balanced) to  
minimize transmission line reflections.  
Applications  
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  
protection for sensitive electronic components that  
may be subjected to electrostatic discharge (ESD).  
The input and output pins are designed and  
characterized to dissipate ESD strikes of 15kV  
safely,  
a
level well beyond the maximum  
requirements of the IEC 61000-4-2 international  
standard.  
Using  
the  
MIL-STD-883D  
(Method  
3015)  
specification for Human Body Model (HBM) ESD, all  
pins are protected 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-.  
The USB Specification revision 1.1 provides for two data rates:  
The Full Speed signaling bit rate at 12 Mbits per second, and  
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).  
Connections for Full Speed Operation  
Full Speed devices have the pull-up resistor (R2) connected to the D+ data line, as shown in Full Speed  
Connection. Pin1 is tied to the D+ line of the USB controller. Pin 6 is connected to the D+ line on the USB  
connector.  
Connections for Low Speed Operation  
Low Speed devices have the pull-up resistor (R2) connected to the D- data line, as shown in Low Speed  
Connection. Pin 1 is tied to the D- line of the USB controller; pin 6 is connected to the D- line on the USB  
connector.
