The RME TCO-HDSPe is an optional extension for selected RME cards. Placed in a free slot of the computer chassis the TCO will be connected with the main card via a flat ribbon cable.

The RME TCO HDSPe provides the HDSPe cards with a Word Clock input and offers a synchronization to LTC and video. The TCO not only extracts absolute positions from LTC, but also a very clean low-jitter word clock from LTC and video. Thus a sample accurate timecode synchronization to audio or video sources is assured. One single TCO can be used with different HDSP/HDPe cards at the same time (multicard), if connected to a supported card

The RME TCO has a combined switchable Word Clock/Video input (BNC) as well as an LTC input (BNC). The Word Clock /Video input on the card can comfortably be terminated (relay-controlled) with a 75 Ohm terminator from the settings dialog. The TCO also features an additional LTC output (BNC) with two level settings (configurable via jumper).
