Hi: I've got the TVB 1 PPS PIC circuit working and would like to add an output IC to drive 50 a couple of Ohm cables. Need two outputs, the normal 1 PPS and also the 10 kHz output since I think it would work with the SRS app note for making 1,000 TI measurements in one second to better see small offsets.
I seem to remember that there may be an internal resistance already in some chips so putting a 47 or 50 Ohm resistor in series may result in an impedance above 50 Ohms. Any thoughts?
