com LX7202-xx I N T E G R A T E D P R O D U C T S EMI Filter & ESD Protection for Up Stream USB Ports P RODUCTION D ATA S HEET KEY FEATURES ƒ Bi-directional EMI/RFI low-pass filter ƒ Line termination with integrated ESD protection ƒ Low TVS operating voltage (5.
25V) ƒ Low leakage current ƒ Integrated single die construction ƒ Available with 15 or 22Ω Series Resistance ƒ Crosses from Semtech STF202 APPLICATIONS DESCRIPTION The LX7202 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 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 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 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.
