• IRIG-A and IRIG-B timecode reader
• IRIG-B timecode generator
• Freewheel capability
• Time-Tag input
• Programmable start/stop time output and interrupt capability

The Spectracom Model 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 the board can be used as an IRIG-B timecode generator by setting the initial time via the IP bus.

The input timecode is automatic and can be enabled/disabled via the IP bus. A propagation delay offset may be specified 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.
