That's great news!
The 6562 is a dedicated differential LVDS device so it is always
expecting a differential signal. The LVDS specification says that
the differential swing must be larger than +/-50mV and should not
exceed an absolute voltage range of 0V to 2.4V.
The 6562 has an associated connector block called the SMA-2164.
This takes the differential cable and breaks each signal out to a
individual SMA coaxial connectors. More information on this

The best results will be achieved by driving differential signals to
each of the pair of SMA. However, if you only have single ended
signals available that are within the specifications of the absolute
input range then you could simply drive that single ended signal to the
postive terminal and a signal at roughly half the swing to the
complimentary. You do not gain the benefits of a differential
signal in terms of canceled crosstalk and EMI but you do drive the
differential stage such that the logic will toggle.
Does that make sense?
