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
pull-down resistors (R2) for
both USB data lines (D+ and D-) as well as the capaci-
tors to ground for EMI suppression. Zener diodes pro-
vide ESD protection up to 15kV contact discharge per
the IEC 61000-4-2 standard and protect the USB con-
troller 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.
