Programmable start/stop time output and
interrupt capability

The TPRO-IP 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. Other features include
a time-tag TTL input and a programmable “match” start/stop time output (with interrupt
capability).
The board continues to increment time (“freewheel”) in the absence of an input timecode.
Thus, by setting the initial time via the bus, the board can be used as an IRIG-B timecode
generator.
The input timecode is automatic and can be enabled/disabled via the bus. A propagation
delay offset can be specied to compensate for cable 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.
