Hi,
I would like you to confirm about threshold of RX signals.
According to datasheet.
1. Each RX is biased by 0.5 * Vcc (In fact generated by dividing resistance (24k ohm))
2. "differential input sensitivity" is defined "max = 200mV"
From above information, I guess that Vih for following each case are defined as shown below. Is my understanding correct ?
In case of Single End (RX- is connected GND).
* RX+ : Vih(min) = (0.5 * Vcc) + 0.2V (Ex. If Vcc = 3.3V, Vih(min) = 1.85V)
In case of Differential.
* RX+ : Vih(min) = (0.5 * Vcc) + 0.1V (Ex. If Vcc = 3.3V, Vih(min) = 1.75V)
* RX- : Vih(min) = (0.5 * Vcc) + 0.1V (Ex. If Vcc = 3.3V, Vih(min) = 1.55V)
I woluld like you to confirm whether we can also understand "differential input sensitivity" mean threshold of Vih/Vil or not.
Best Regards,
