DESCRIPTION
The LX7203 is an integrated
Universal Serial Bus (USB) line
termination device with an EMI filter
and ESD protection diodes. This
device offers a cost effective and
compact solution for one USB
upstream port.
The USB v1.1
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
k pull-up resistor identifies the
appropriate data line for full speed or
low speed operation.
The 47 pF capacitor completes the
high frequency filter and controls the
edge rate of the USB signals The
LX7203 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 LX7203 minimizes board space
and allows for ideal placement near the
connector. The LX7203 is ideal for use
in USB hubs, peripherals and portable
appliances
