The STF203 is a combination EMI filter and line
termination device with integrated TVS diodes for use
on upstream USB ports. It is constructed using a
proprietary technology that allows passive components
and TVS diodes to be integrated in the same package.
Each device will provide termination, filtering, and ESD
protection for one upstream USB port. The STF203 is
an easily implemented solution for meeting the
requirements of revision 1.1 of the Universal Serial Bus
specification.
Line termination is achieved with series resistors on
both the D+ and D- USB lines. The value of series
resistance added to the output impedance of the USB
driver must be as close to possible to the 45
characteristic impedance of the cable (90
to minimize transmission line reflections. They are
available with resistor values of 15
22
pull-up resistor is required by the USB specification to
identify the equipment as either a full-speed
(connected to D+ line) or low-speed (connected to D-
line) device. The 47pF capacitors are required to
bypass high frequency energy to ground and to control
the edge rate of the USB signals. The TVS diodes
provide ESD protection of both (D+ and D-) data lines
and the voltage bus (V
input/output pins provide suppression of ESD voltages
in excess of ±15kV (air discharge) and ±8kV (contact
discharge) per IEC 61000-4-2, level 4. The TVS diode
