The STF202 is a combination EMI filter and line termination device with integrated TVS diodes for use on upstream 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 upstream USB port. The STF202 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 22Ω or 30Ω resistors on both the D+ and D- USB lines.
The Semtech STF202 is a combination EMI filter and line termination device with integrated TVS diodes designed for use on upstream USB ports. It integrates passive components and TVS diodes in a single SOT-23 6L package to provide termination, filtering, and ESD protection for one upstream USB port. The device helps meet the requirements of revision 1.1 of the Universal Serial Bus specification by achieving USB line termination with series resistors and providing ESD protection for data lines and the voltage bus.
