Dual GPS clock maintains synchronisation

The Synchronisation Division of Tekelec Systemes (Martec) has unveiled a fully redundant version of its Epsilon GPS clock.

The Synchronisation Division of Tekelec Systemes (Martec) has unveiled a fully redundant version of its Epsilon GPS clock.

This equipment has been developed specifically to meet the needs of SFN (isofrequency) terrestrial digital audio and TV broadcasters.

The Epsilon Dual GPS will prove particularly relevant to radio and TV broadcast network managers, digital radio and TV equipment suppliers, and radio and TV integrators.

The Epsilon Dual GPS clock provides all the technology required to ensure maximum and permanent reliability of synchronisation, from the SFN adapters of head-end terminals to high and low power transmitters and local repeaters.

The 19in/1U chassis of the Epsilon Dual GPS clock allows for easy installation into racks.

And an IP interface is provided for monitoring via the Internet.

The Epsilon Dual GPS receivers track up to 12 satellites each, with external reference backed up at 10MHz or 1pps.

They are based on dual OCXO oscillators and fitted with dual AC/DC power supply.

Switching between clocks occurs with no phase jump, and the receivers' accuracy to UTC is +/-35ns peak-peak.

Other features include six 10MHz and six 1pps phased locked outputs, fast warm-up, local or remote (IP) monitoring, alarm dry relay, and optional NTP output.
