FreeLists / si-list / [SI-LIST] Re: Maximum length of 1000basetT diff pair traces from PHYs to magnet ics

[Larry Miller <ldmiller@xxxxxxx>]

It really depends on how well matched your transformer and PHY ports=20
are.

Remember, the signals in 1000BASE-T are the same frequencies and=20
rise/fall times as 100BASE-TX. You aren't really dealing with 1G=20
signals here.
