EMI Filter and line termination for USB upstream
ports on:
- USB Hubs
- PC peripherals
APPLICATIONS
I
Monolithic device with recommended line termi-
nation for USB upstream ports
I
Integrated Rt series termination and Ct bypass-
ing capacitors.
I
Integrated ESD protection
I
Small package size
DESCRIPTION
FEATURES
The USB specification requires upstream ports
to be terminated with pull-up resistors from the
D+
and
D-
lines
implementation of USB systems, the radiated
and conducted EMI should be kept within the
required
levels
as
regulations. In addition to the requirements of
termination
and
EMC
computing devices are required to be tested for
ESD susceptibility.
The USBUFxxW6 provides the recommended line
termination while implementing a low pass filter to
limit EMI levels and providing ESD protection
which exceeds IEC61000-4-2 level 4 standard.
The device is packaged in a SOT323-6L which is
the smallest available lead frame package (50%
smaller than the standard SOT23).
