USBDF01W5 - EMI filter and line termination

General Description

The USB specification requires USB downstream ports to be terminated with pull-down resistors from the D+ and D- lines to ground.

On the implementation of USB systems, the radiated and conducted EMI should be kept within the required levels as stated by the FCC regulations.

Key Features

  • Monolithic device with recommended line termination for USB downstream ports.
  • Integrated Rt series termination and Ct bypassing capacitors.
  • Integrated ESD protection.
  • Small package size.
