Frequency References

Tycho CDMA Frequency Reference
Easy Installation - No rooftop antenna required

Frequency Reference
The Tycho CDMA Frequency Reference lowers the cost of any frequency control project and makes an ideal time and frequency standard.  This rackmount unit uses CDMA rather than GPS as its timing source, allowing you to locate the antenna anywhere you can receive a cell phone signal.  This saves you the trouble and expense of installing a GPS rooftop antenna.
60-Day Money-Back Guarantee
  • Indoor antenna convenience.
  • A 1 PPS output which is synchronized to UTC to within 10 microseconds (typical).
  • Stable frequency reference, almost as good as direct GPS.
  • An amplitude-modulated, user-selectable timecode output (IRIG-B, NASA-36, 2137).
  • A network port with SSH, Telnet, FTP, SNMP, Enterprise MIB and more.
  • An RS-232 serial port.
  • Two-year warranty, free technical support and software upgrades for life.
  • Options: OCXO, Low Phase Noise Outputs, Telecom Clock Outputs, 10 MPPS, Pulse Rates, Alarm, -48Vdc Input and more.
The Antenna Advantage
Most precise time receivers require an antenna that must be installed on the roof of your building, with good sky visibility.  The Tycho CDMA Frequency Reference eliminates this problem by synchronizing to within 10 microseconds of UTC using signals broadcast from the CDMA cellular telephone system.  You benefit by not having to install a rooftop antenna and still having a timing reference that is almost as stable as with GPS.

Oscillator Option
The Tycho can be configured with a medium-stability, high-stability or ultra-stable OCXO with SC-cut resonator.  Click here for datasheet.

Low Phase Noise (LPN) Output Option
This option provides four or eight isolated, 5 or 10 MHz, frequency output signals with exceptional spectral purity.  Careful attention to power supply filtering and signal routing preserve the same high-performance phase noise and spurious noise characteristics as the source oscillator.  Click here for datasheet.

Telecom Clock Output Option
This option module provides two or four outputs which can be any combination of E1, T1 or Composite Clock.  An alarm output is available as an additional option.  SSM is supported.  Click here for datasheet.

More Options
Several other output options are available.  Click here for datasheet.  These outputs, which provide additional flexibility in configuring your Meridian GPS Frequency Standard, are:
  • One, two, four or eight programmable pulse rate outputs.
  • Four or eight buffered analog timecode outputs.
  • A direct digital synthesizer (DDS).
  • An alarm output.
  • A second serial port with a once-per-second, on-time, serial timestring.
