Measurement condition
Favorable transmission waveforms are achieved with
appropriate CMF(common-mode filter) character-
istic impedance* and low differential-mode imped-
ance.
Measurement results
For operational test, the same EMI countermeasure
components are implemented on both the signal
sending and receiving sides, assuming actual use
conditions.
The measurement data below are the results of ob-
servation at a point near TP3 using 0.5m cables. To
observe the characteristic superiority of TCM, the TP2
template, which is more severe than TP3, was used.
Actual measurement example of
USB2.0 differential signal waveform
TCM1005
At the USB2.0's data transmission speed (High speed)
of 480Mbps, repetitive pulse frequency is 240Mhz,
which requires sufficient consideration for effects on
the signal waveform when selecting EMI counter-
measure components to deter the radiation noise
from the cables, etc.
The USB2.0 transmission signal waveforms where no
EMI countermeasure components are attached,
and where TCM1005-900-2P is attached near the
connectors for both HUB and DEVICE are as follows:
*CMF(common-mode filter) characteristic impedance:
With the USB2.0 standard, the required characteristic impedance
of a common-mode filter is 90
