Most of the gear I have expects TTL levels or better. A 0.6 volt RMS sine wave (1.2 volts peak to peak) could be a problem. As far as ringing, I would design something with back termination and slew rate limiting and expect the receiver to terminate to ground which is almost always the situation. I looked at the TADD-3 design and it sacrifices back termination impedance for signal swing which results in ringing but I presume not too much if people were using it successfully.
If there are time nuts then why not impedance, edge, and transconductance nuts?
