DESCRIPTION
The USB specification requires upstream ports to
be terminated with pull-up resistors from the D+
and D- lines to Vbus. On the implementation of
USB systems, the radiated and conducted EMI
should be kept within the required levels as stated
by the FCC regulations. In addition to the
requirements
of
termination
and
EMC
compatibility, the computing devices are required
to be tested for ESD susceptibility.
The USBUF01P6 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 SOT-666 which is the
smallest available lead frame package (45%
smaller than the standard SOT323).
