EMI Filter and line termination for USB
downstream ports on:
Features
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. In
addition to the requirements of termination and
EMC compatibility, the computing devices are
required to be tested for ESD susceptibility.
The USBDFxxW5 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 standard.
The device is packaged in a SOT323-5L, which is
a very small (50% smaller than the standard
SOT23).
Complies with the following standards
IEC 61000-4-2, level 4 ±15 kV (air discharge)
MIL STD 883C, Method 3015-6
Class 3 C = 100 pF R = 1500 W
3 positive strikes and 3 negative strikes (F = 1 Hz)
