Description
The STF201 is a combination EMI filter and line termi-
nation device with integrated TVS diodes for use on
downstream 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 downstream USB port. The STF201
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 22
or
30
resistors 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 15k
pull-down resistors complete the termination circuit on
each line. They are required by the USB specification
to identify the line as a downstream connection. The
47pF capacitors are used to bypass high frequency
energy to ground and for edge rate control of the USB
signals. Finally, the STF201 contains TVS diodes for
ESD protection of both (D+ & D-) data lines and the
voltage bus (V
). The TVS diodes provide effective
suppression of ESD voltages in excess of 15kV (air
discharge) and 8kV (contact discharge) per IEC 61000-
4-2, level 4.
The small size and integrated feature of the STF201
minimizes required board space and increases system
reliability. The pin-out of the device allows easy imple-
mentation. The STF201 is suitable for use in USB
hubs, computers, peripherals, and portable devices.
