Universal Serial Bus (USB) line
termination device with an EMI filter
and ESD protection diodes. This
device offers a cost effective and
compact
upstream port. The USB specification
requires line termination resistors on
both the D+ and D- lines. These
resistors ensure signal integrity by
matching the cable impedance to that
of the differential driver. The 1.5 kΩ
pull-up
appropriate data line for full speed or
low speed operation.

LX7202 protects both D+ and D- data
lines and the voltage bus from ESD. The
TVS protection diodes exceed the
requirements of IEC61000-4-2, level 4,
15kV (air discharge) and 8kV (contact
discharge).The integrated configuration
of the LX7202 minimizes board space
and allows for ideal placement near the
connector. The LX7202 is ideal for use
in USB hubs, peripherals and portable
appliances.
