Hello team,
I'm trying to determine if the SN65LVDS391 can be used as a driver for a mini-LVDS reciever. The specs for the mini-LVDS receiver are as follows:

The differential specs for our SN65LVDS391 are:
I'm trying to make sense out of these specs to make a confident decision:
The mini-LVDS receiver can detect a differential signal as low as 150mV (min. VID). Is it correct to say, for a worst case scenario, our SN65LVDS391's differential logic swing is min 247mV +/- 50mV, so it can be as low as 197mV, which is still enough for the mini-LVDS to detect the differential swing? Will the SN65LVDS391 be a good driver for this mini-LVDS receiver?
If not, what is our best offering for this application. Thanks.
