Model TPRO-S Multi-function Timecode Reader/Generator
The TPRO-S performs timing and synchronization functions referenced to an input timecode signal. The board synchronizes its on-board clock to the incoming timecode. The on-board clock’s time is also provided as an IRIG-B output. An input is provided to time-tag external events.
The board continues to increment time (“freewheel”) in the absence of an input timecode. Thus, the board can be used as an IRIG-B timecode generator by setting the initial time via the bus. The input timecode format (IRIG-B, IRIG-A, or NASA36) is detected automatically. Synchronization to the input timecode is also automatic and can be enabled/disabled via software. A propagation delay offset can be specified to compensate for any delays.
The timecode input is an amplitude modulated sine wave. An automatic gain control (AGC) circuit permits a wide range of input amplitudes. The timecode input is differential; the board does not reference this signal to ground. A single-ended input (referenced to ground) is also acceptable.
The board can be ordered with option “–M” to synchronize to a one-pulse-per-second (1PPS) input instead of an incoming timecode. In this case, the initial time is programmed via the bus, and the board begins counting on the next 1 PPS pulse.
