The TCO module is an optional extension for certain RME cards/systems. It is inserted into a free slot of the housing and connected to the motherboard by a narrow ribbon cable. The small plug-in module equips the HDSP/HDSPe cards with a word clock input, and also opens the possibility of synchronization to LTC and video. Thanks to SteadyClock the TCO not only extracts absolute position information from LTC, but also a very low jitter word clock from LTC and video. This ensures connection and sample accurate timecode synchronization to any audio and video feed.
A TCO can be used with multiple cards simultaneously, provided that a card supporting the TCO is present in the network.
LTC can be generated or derived in all common formats: 24, 25, 30 or 29.97 frames; drop or non-drop. Common pull-up and pull-down formats (+/- 0.1% and +/- 4%) are supported. PAL and NTSC video formats are automatically detected and correctly processed.
Received timecode can be forwarded to audio/video applications as APP (ASIO Positioning Protocol) or MTC. On the other hand, the TCO is also able to generate low jitter LTC from received APP or MTC signals directly on hardware level, without interaction by a software or driver routine. Various chase functions (adjustable drop-out length, continuous or jam sync) are supported.
On Windows, the TCO provides SMPTE position information in APP (ASIO Positioning Protocol) and as MTC Sync. Under Mac OS X, the TCO provides the SMPTE position information only as MTC Sync. On the hardware side, the TCO has a switchable word clock/video input (BNC, terminable) and an LTC input (BNC). The two-stage LTC output (BNC) is configurable via jumper.
