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.
