FreeLists / si-list / [SI-LIST] Re: Crosstalk in time units

["Hassan O. Ali" <hassan@xxxxxxxx>]

A quick-and-dirty voltage-to-time crosstalk conversion technique is as follows:

Crosstalk (in time) = Crosstalk Voltage peak-to-peak/Signal Slew-rate

Assumptions:

- crosstalk doesn't change the slew-rate of the signal - just advances or 
delays the 
signal
- crosstalk happens during the rising/falling edge of the signal (not after 
settling)

Best regards.

Hassan.
