LMH7220: Consideration of Hysteresis

Guru 16770 points
Part Number: LMH7220

Hi

We are referring SNOA478A User's guide and we have question about introducing external hysteresis.

According to the receiver circuit in Figure 1, the feedback resistor is 6Kohm.

And 50ohm termination seems to be offered as a resistor as divider portion along with 6Kohm for hysteresis.

If so, how to calculate hysteresis?

Is the following calculation for hysteresis correct?

50ohm/(50ohm + 6000ohm) * Vod = ~2.7mV  , 2.7mV is hysteresis?

BestRegards
