Nope, this came out well before that “era”.

It depends a bit on which rev of the hardware / firmware it is. 10’s of ns on the counter and a basic analog approximation past that. The design dates to just past “the turn of the century”. The grubby details are going to be very hard to dig up.

Me being obnoxious I kept doing these designs inhouse because what we where doing was not fitting a standard scheme. We still do not match that, even if I do a standard out of what we have done. Ah well, the other way around. :)
