The USBUF01W6 is an EMI Filter and Line Termination for USB upstream ports. The low-pass EMI analogue filter specification requires upstream ports to be terminated with pull-up resistors from the D+ and D- lines to Vbus. On the implementation of USB systems, the radiated and conducted EMI should be kept within the required levels as stated by the FCC regulations. The filter provides the recommended line termination while implementing a low pass filter to limit EMI levels and providing ESD protection which exceeds IEC 61000-4-2 level 4 standards.
Integrated Rt series termination and Ct bypassing capacitors
EMI/RFI noise suppression
Required line termination for USB upstream ports
