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 dischagre
(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.
