“LTC Generate“: LTC Generator Functions
TCC70XS can output the data of the time code generator in an LTC format.

Gain
Select the output level from the drop

down list.
The values in this list refer to a use of balanced signals for output and input, i.e.
V
PP
(= peak
–
to
–
peak value) will be the difference between LTC_OUT_A and
LTC_OUT_B. V
PP
will be half of the indicated value if unbalanced signals are used,
i.e. the peak

–
peak value of the single LTC_OUT_A or LTC_OUT_B signal.
Correspondence between balanced use and unbalanced use:

This function can be programmed for a function key or a GPIO as well.
PC bit
If checked: the polarity of the synchronization word of the LTC output will be
stabilised. The polarity correction bit is put in a state, so that every 80
–
bit word
contains an even number of logical zeros. The polarity correction bit is bit no. 27
in the 525/60 system, bit no. 59 in the 625/50 system. Checking this checkbox is
helpful if you do some LTC measurements with an oscilloscope.
