I would like you to confirm about below.
* According to datasheet, maximum and typical "Vid" value is defined.
However, there is no spec for minimum value.
On the other hand, there is following figure in datasheet.
* Figure 6-13. AC Performance vs Clock Amplitude
According to this figure, TI estimate approximate 0.25V as minimum value of sampling clock.
I think that the reason TI defined only from 1V is stable and best perfomance of SNR become over Vpp = 1V.
In other words, I believe although the noise characteristics are somewhat worse, a minimum of 0.25 Vpp is acceptable as an input.
Is my understanding correct ?
(In case of general LVDS, center value of Vpp is defined 0.7Vpp, so if my above understanding is correct, user can choose such interface.)
