SN65LVDS9637: Hysteresis or Schmit Trigger on Input

Tyler Berezowsky17

Part Number: SN65LVDS9637

Hello!

We're utilizing TI's LVDS receivers in one of our designs in a high noise environment. The receiver has the following table:

Is the output between the +/- 100mV threshold indeterminate because it's not time invariant, but it will latch the output to the previous state or is it actually complete indeterminate...

Hi,

The output here is completely indeterminate.

I can see in another post the typical threshold for this part is +/-30mV is this still valid? Also thanks!

Hi,

+/-30mV is not valid. VITH+ and VITH- indicates how this part would switch with respect to VID.
