Would you mind if we ask SN65LVDS391?
How much is MAX Toggle Frequency?
As the background of this question, our customer would like to use SN65LVDS391 with 450Mbps.
The datasheet shows "Designed for Signaling Rates Up to 630 Mbps."
As the device characteristics, except for using cable and cable construction, we assume that it is possible to use for 630 Mbps system.
And then, Prorogation Delay H->L and L=H are MAX1.7ns.
So, we assume that 1.7ns pules are acceptable, otherwise it seems that MIN 294MHz is accetable.
If you have some advice, could you let us know?
