PACUSBD
USB Downstream Port
Terminator
Product Description
The PACUSB−D1/D2 is a single−channel USB downstream−port
termination network. It integrates EMI/RFI filter components R1 and
C1, as recommended by the USB specification as well as the required
15 kW pull−down resistors (R2) to GND. In addition,
PACUSB−D1/D2 provides a very high level of protection for sensitive
electronic components that may be subjected to electrostatic discharge
(ESD). The device pins will safely dissipate ESD strikes of 15 kV,
exceeding 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 from contact discharges to 20 kV.
There are three options for the value of the series resistor R1: 15 W,
22 W, and 33 W. This series resistance, plus the USB driver output
resistance, must be close to the USB cable’s characteristic impedance
of 45 W (each side) to minimize transmission line reflections.
The PACUSB−D1/D2 is manufactured in a 5−pin SC70 or a 5−pin
SOT23 package and is available with optional lead−free finishing.
