Hello,
I have a question below on the SN65LVDS93A-Q1.
In section 6.5 there is an Electrical Characteristic parameter called “delta |VOD|- Change in the steady-state differential output voltage magnitude between opposite binary states”.
We’re not clear on what that is or if we’re measuring it incorrectly but what we ‘believe’ it is saying is “find the difference between the magnitudes of the steady-state voltages when the signal reaches “HI” and “LOW”.
For instance, say “HI” was 394mV and “LOW” was -290mV => |394| - |290| = 104mV which greatly exceeds the 1-35mV cited in the datasheet.
After looking/thinking about this a bit more, it almost seems like that parameter is stating a change in the steady-state voltage over a period of time guaranteed by the IC (and not really a measurement ‘we’ could impact with PCB layout)…i.e. that 394mV would stay within 359mV to 429mV (394+/-35mV) and the -290mV would stay within -325mV to -255mV (-290+/-35mV) if one were to have infinite persistence on an oscilloscope…a sort of steady-state voltage jitter so to speak?
Any insight you could help provide would be greatly appreciated!
Thanks!
Connor
