    5 Master oscillator 5 Master oscillator By default the TCR180 is equipped with a TCXO (Temperature Compensated Xtal Oscillator) as master os- cillator to provide a good time accuracy and frequency stability. As long as an input signal is supplied the frequency of the oscillator is adjusted from the input signal, and if the input signal is disconnected afterwards the card can still provide accurate time for a certain holdover interval.

    So care must be taken that the on-board clock has been set to the correct date. The on-board date and time can be adjusted by sending a Meinberg Standard Time string to the serial interface COM0, or via the PCI bus by using the utility programs included in the driver software package.
  • Page 15 6 Functional description of receiver The TCR180 can automatically convert its on-board UTC time to some local time, including automatic switching to and from DST year by year according to configurable rules. This is independent from the UTC offset of the incoming time code.

  • Page 18: Functionality Of The Generator

    7 Functionality of the generator The time code generator of TCR180 is based on a DDS (Direct Digital Synthesis) frequency generator which derives the sine carrier of the modulated code from the reference clock of the master oscillator. The modulation of carrier amplitude (modulated codes) or pulse duration (unmodulated, DC level shift codes) is synchronized to the generated pulse-per-second (PPS) signalderived from the software clock.

  • Page 19: Pulse Outputs

    7.2 Pulse outputs The pulse generator of the TCR180 generates pulses for the seconds change (P_SEC) and the minute change (P_MIN). In addition, fixed output frequencies of 10 MHz, 1 MHz and 100 kHz are derived from the OCXO. All these signals are carried out with TTL level on the back-side connector (VG96).

  • Page 20: Enabling Of Outputs

    COM0 is compatible with other radio remote clocks made by Meinberg. It sends the time string either once per second, once per minute or on request with ASCII ´?´ only. Also the interfaces can be configured to transmit capture data either automatically when available or on request.

    UTC must be set up by the monitor software. In contrast to AFNOR NF S87-500 the IRIG telegram containes only the day of year (1...366) instead of a complete date. To ensure correct function of TCR180, the date stored in the realtime clock of the board must be set when using IRIG codes therefore. This setting can be done by a terminal software also.

    Hundreds of different time codes were formed, some of which were standardized by the "Inter Range Instrumentation Group" (IRIG) in the early 60´s. The TCR180 supports decoding and generating of IRIG-A, IRIG-B, IRIG-G, AFNOR NF S87-500, IEEE C37.118 and IEEE 1344.
