PACUSBU-S
Upstream USB Port
Terminator
Product Description
The PACUSB−U1, PACUSB−U2, and PACUSB−U3 are
single−channel USB upstream−port termination networks.
The PACUSB−U1/U2/U3 integrate EMI/RFI filter components R1
and C1, as recommended by the USB specification. Because these are
upstream USB devices, they are terminated with a single 1.5 kW
pull−up resistor to V3.3 (R2).
There are three options for the value of the series resistor R1:
For PACUSB−U1, R1 = 15 W
For PACUSB−U2, R1 = 33 W
For PACUSB−U3, R1 = 22 W
This series resistance plus the USB driver output resistance must be
close to the USB cable’s characteristic impedance of 45 W (90 W
balanced) to minimize transmission line reflections.
In addition, these parts provide a very high level of protection for
sensitive electronic components that may be subjected to electrostatic
discharge (ESD). The input and output pins are designed and
characterized to dissipate ESD strikes of 15 kV safely, a level well
beyond the maximum requirements of free finishing.
