DESCRIPTION
The STF202 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
STF202 is an easily implemented solution for meeting
the requirements of revision 1.1 of the Universal Serial
Bus specification.
USB line termination is achieved with series 22or
30resistors on both the D+ and D- USB lines. These
resistors preserve signal integrity by matching the
cable impedance to that of the differential driver. The
1.5kpull-up resistor completes the termination circuit
on each line. This 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 used to
bypass high frequency energy to ground and for edge
rate control of the USB signals. Finally, the STF202
contains TVS diodes for ESD protection of both (D+ &
D-) data lines and the voltage bus (VBUS). The TVS
diodes provide effective suppression of ESD voltages
in excess of 15kV (air discharge) and 8kV (contact
discharge) per IEC 1000-4-2, level 4.
The small size and integrated feature of the STF202
minimizes required board space and increases system
reliability. The STF202 is suitable for use in USB hubs,
computers, peripherals, and portable devices.
