For most of our products the timecode output is designed for the analog world. The level is fixed at 1.2v Peak to Peak with a 40uSec rise time and rounded corners in order to minimize crosstalk Recently we have noticed a number on computer based systems that require a higher level on the timecode output. Where I have fitted a gain resistor this is quite easy, just add a suitable resistor, where this is not possible the simplest solution is to double up the diodes as shown in the diagrams below .
