It wasn't really ahead of its time with the 'jitter' thing. There was a serious issue with early toslink receivers and transmitters unable to maintain an even duty cycle and practically all the external two box or transport/dac combos used a simple circuit like this switchable one to fix that issue. All digital input amplifiers from the late 80s had similar circuits after the toslink receiver to do exactly the same. Jitter has come to mean something else these days, in this case, it was for consistent duty cycle correction- nothing more.
