PACUSB-U1/U2/U3 Upstream USB Port Terminator Features Product Description • The PACUSB-U1, PACUSB-U2, and PACUSB-U3 are single-channel USB upstream-port termination networks. • • • • One upstream USB port terminator, EMI filter and transient overvoltage protector in a single surfacemount 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 components R1 and C1, as recommended by the USB specification. Because these are upstream USB devices, they are terminated with a single 1.5kΩ 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 Applications • • • • • • • 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. 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.

It provides series termination, EMI filtering, and ESD protection for the two USB data lines D+ and D-. Full Speed devices have the pull-up resistor (R2) connected to the D+ data line, as shown in Figure 1. Pin1 is tied to the D+ line of the USB controller. Pin 6 is connected 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 • The Low Speed signaling bit rate at 1.5 Mbits per second. Connections for Low Speed Operation 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). Low Speed devices have the pull-up resistor (R2) connected 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 connected to the D- line on the USB connector.
