TPRO-IP - Multi-function Timecode Reader/Generator
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 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.
