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-

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.

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
