IRIGB synchronisation board TMC2203

The TMC2203 card is a synchronization card in PCI EXPRESS format allowing and providing a time base of good stability from an IRIG B type synchronization source. Base time With a local oscillator, the board maintains an internal time which is synchronized with the reference signal. This time is made available to the computer hosting the card through registers accessible via the PCI bus. The internal oscillator is also frequency-controlled on the reference signal so as to ensure a minimum drift of the time delivered when the reference is not available. The reference signal is configurable (source IRIG B or source 1 PPS). IRIG B Synchronization The IRIG B signal is a 1 KHz carrier signal modulated in amplitude (code B12x) or an unmodulated signal. The card handles IRIG B protocols containing or not the "year" information. For standard IRIG B, information is not present in the code and is managed by the card from an original year provided by the user. Leap years are also taken into account. The board also supports the IRIG B TD, H0 and TU/TD composite protocols by configuration.
