definition, a transformer, even if the turns counts are equal"
You've never seen a line choke ? The leads of the AC power go through each winding, and the transformer action helps it to block common mode high frequency noise.
It is 4 terminals and not used as a transformer. The turns ratio is 1 : 1.
A common mode (CM) choke should be used to terminate the high speed USB bus if they are need to pass EMI testing. Place the CM choke as close as possible to the connector pins. See Section 5.1 for details.
Note: Common mode chokes degrade signal quality, thus they should only be used if EMI is a known problem.
You don't know much do you ? But you think you do. Crosstalk to what brainiac ?
Hey Einstein, it is there to keep the USB wire from becoming an antenna and radiating RF. If you call that crosstalk, what do they call a volt on your planet Mr. Spock ?
What's more you are so smart and mature you think calling people who correct you names. Your credibility is in the negative on this one dude.
so it is a transformer there to reduce crosstalk. OK, do you work for the government ? You got your degree in basketweaving ? Your busy season is coming - Easter !
Stay away form sci.electronics.basics, we don't need another generation or recalls, refits and really f***ed up engineering. Maybe you should try one of those solutions manuals, or is that how you "learned" ?
k is not the dipshit here. There is one. Can you guess who ?
Something else, AlwaysWrong. The CM choke is there to eliminate COMMON (even) MODE noise. Common mode noise is *NOT* crosstalk. You're still perfectly always wrong, AlwaysWrong.
