AVR-Chat

Hello, wonder if someone could point me in the right direction regarding an
old line scan camera that I am attempting to control using an AVR. The
camera supply is +5v and +15v. Basic point is that the data rate and line
rate signals are just specified as differential line driver signals and
shown as having a +ve and -ve connection and a comment is made that for slow
speed access the -ve pin could be biased with +1v and a TTL signal applied
to the +ve pin. Would I be okay in using a JK flip flop wired to toggle and
use the Q, Q bar outputs,  maybe just connect each pin to the AVR and toggle
the lines or should I use say a RS422 driver,. Afraid that I have no
experience of differential line drivers and appreciate any help in this
area.
