| PACUSB-U1/U2/U3 Upstream USB Port Terminator Features * * * * * 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 Product Description 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 1.5k pull-up resistor to V3.3 (R2). There are three options for the value of the series resistor R1: * For PACUSB-U1, R1=15 * For PACUSB-U2, R1=33 * For PACUSB-U3, R1=22 This series resistance plus the USB driver output resistance must be close to the USB cable's characteristic impedance of 45 (90 balanced) to minimize transmission line reflections. 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-. 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 1.5k pull-up resistor (R2). PACUSB-Ux D+ Connections for Full Speed Operation 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. Connections for Low Speed Operation 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. 1 IN1 R1 C1 R2 6 OUT 1 D+ D1_i D1_c 3.3V USB CONTROLLER GND D- GND 2 5 Vcc C1 GND V3.3 R1 SC70-6 4 OUT 2 D- USB CONNECTOR 3 IN2 D2_i D2_c Figure 1.
