PACUSB-D1/D2/D3
USB Downstream Port Terminator
Features
Product Description
•
A low-capacitance USB downstream port termina-
The PACUSB-D1/D2/D3 is a single-channel USB
downstream-port termination network. It integrates
EMI/RFI filter components R1 and C1, as recom-
mended by the USB specification as well as the
required 15kΩ pull-down resistors (R2) to GND. In
addition, PACUSB-D1/D2/D3 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
+15kV, 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 +20kV.

There are three options for the value of the series
resistor R1: 15Ω, 22Ω, and 33Ω. This series resis-
tance, plus the USB driver output resistance, must be
close to the USB cable’s characteristic impedance of
45Ω (each side) to minimize transmission line reflec-
tions.

Note 1: Electrical operating characteristics guaranteed over standard operating conditions unless specified otherwise.
Note 2: Guaranteed by design and characterization.
Note 3: ESD voltage applied to pins with respect to GND, one at a time; unused pins are left open.
Note 4: Pins 1 and 3 are not connected to the USB port connector, and therefore are not exposed to external ESD hazards. Thus,
they do not require the high ESD protection levels provided for pins 4 and 5.
Note 5: ESD Clamping Voltage is measured at the opposite end of R1 from the pin to which the ESD discharge is applied (e.g., if
ESD is applied to pin 6, then the clamping voltage is measured at pin 1).

PACUSB-D1/D2/D3
Application Information
The PACUSB-D1/D2/D3 provides a complete interface
for a single downstream USB port typically found in
computers and USB hubs. It integrates the series
resistors (R1) and the 15kΩ pull-down resistors (R2)
for both USB data lines (D+ and D-) as well as the
capacitors to ground for EMI suppression. Zener
diodes provide ESD protection up to 15kV contact dis-
charge per the IEC 61000-4-2 standard and protect the
USB controller on both data lines.
The PACUSB-D1/D2/D3 should be placed on the PCB
between the USB controller and the USB connector, as
shown on the Connection Diagram Figure 5.

Figure 5. Connection Diagram for PACUSB-D1/D2/D3 Devices
To guarantee the best ESD and filtering performance,
it is recommended to physically locate the PACUSB-
D1/D2/D3 close to the USB connector. Also, the trace
lengths between the PACUSB-D1/D2/D3 and the USB
controller should be kept as short as possible.
