SYNC Field response waveforms of USB2.0
TCM1005
USB2.0 transmits data over a differential signal of 400
mVp-p. When it completes a session of data trans-
mission, it sends a 32bit interval signal before the next
data transmission.
With a common-mode filter applied as an EMI pre-
ventative, the initial signal of the 32bit signal field
(SYNC Field) is shifted to the negative, so the voltage
peak value decreases far below the initial level when
no countermeasure is taken.
To prevent transmission errors caused by this feature,
it is vital to maintain a voltage over 150mV starting
from the initial bit of the SYNC Field. It is very impor-
tant to consider this when choosing the correct
common-mode filter, as well as the Eye pattern wave
forms standard.
