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.
