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 15k
Ω
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.
