OK thanks, that clarifies things.
So using either DCO or BPO for OUTPUT is personal preference? Do you guys ever wire one half of the pcb to DCO and the other to BPO?
I do plan on using D so that I can have a BIPOLAR OUPUT. Wouldn't that cover the negative modulations as well? I *think* it should output +/-2.5v
Thanks again.
