REF-V01-MO is a synthesizer of reference signals. Its main application is related to generation of high-stability sample frequencies, i.e. the 2.048 MHz or 16.384 MHz (Telecom applications) or 5 MHz and 10 MHz (Broadcasting applications). The sample frequencies generated by REF-V01-MO are extremely stable both for time and temperature. The device internally contains a high stability thermoregulated oscillator (OCXO), with minimum frequency drift. REF-V01-MO also implements two systems used to tune the internal oscillator; in order to obtain, through sophisticated algorithms the frequency references with stability like 1e-12. The first system uses synchronization signals coming from the satellite system NAVSTAR Global Positioning System (GPS) and this is usable worldwide and in all weather condition. The second system uses another sample signal coming from, i.e., an apparatus generically defined as “Central Clock”. This signal might be, i.e., a sine wave with 2.048 MHz frequency, result of the re-generation of an SDH datastream. REF-V01-MO is completely automatic in both system management to tune the internal oscillator. In particular, the user is free to decide to use one in back-up of the other. Concerning the control of stability of the internal oscillator based on GPS receiver, signaling provided by the NAVSTAR navigation system are used. This system was planned by USA Department of Defense and is used to obtain the geographical coordinates of a earth reference. With algorithms is possible generate a high precision synchronization signal usable as time sample.
