EMI Filter and line termination for USB down-
stream ports on:
- Desktop computer
- Notebooks
- Workstations
- USB Hubs
APPLICATIONS
n
Monolithic device with recommended line termi-
nation for USB downstream ports
n
Integrated Rt series termination and Ct bypass-
ing capacitors.
n
Integrated ESD protection
n
Small package size
DESCRIPTION
FEATURES
The
downstream
pull-down resistors from the D+ and D- lines to
ground.
On
the
implementation
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
required to be tested for ESD susceptibility.
The USBDFxxW5 provides the recommended line
termination while implementing a low pass filter to
limit EMI levels and providing ESD protection
which exceeds IEC 61000-4-2 level 4 standard.
The device is packaged in a SOT323-5L which is
the smallest available lead frame package (50%
smaller than the standard SOT23).
