Time and user data can be visibly displayed. Various formats are
selectable, as well as size, position ...
Frequency and phase synchronization
The counting of the time code frames depends on the clock derived from the sync signal. It is
strongly recommended to connect an SD/HD/3G video signal if time code will be used in a
video application. Without video, the sync signal should be
PPS
in REAL
–
TIME mode and
LTC
Read
in JAM SYNC mode, respectively.

TCC70XS offers status feedback at the OLED screen via four independent programmable
status segments. The
Gen Sync Status
function for a status segment indicates the status of the
phase and frequency synchronization of the time code generator, depending on the mode of
sync selection:

Status segment in the “Gen Sync Status“ function
Sync = Internal
Segment is permanently off.
Sync = Video
Segment lights up during video lock.
Segment flashes slowly during the fine trim procedure.
Segment flashes fast if video synchronization is lost.
Sync = LTC Read
Segment lights up during source lock
(LTC signal at LTC_IN_A, LTC_IN_B).
Segment flashes slowly during the fine trim procedure.
Segment flashes fast if LTC synchronization is lost.
Sync = Second Pulse
Segment lights up during lock to the external PPS
(signal input at GPIO_1).
Segment flashes slowly during the fine trim procedure.
Segment flashes fast if PPS synchronization is lost.
