The Maxiva™ GNSS-PTP Time and Frequency Reference Generator has been designed to bring the maximum level of flexibility and reliability to a broadcast or telecom facility. Operating at the highest level of redundancy, the GNSS-PTP features two hot-swappable power supply units, each with batteries that provide up to 30 minutes of uninterruptable operation. Two high-precision GNSS receivers support all major satellite systems.The optional PTP module can provide another level of redundancy for the GNSS receivers. The PTP module can operate in slave and Grandmaster roles.
The timing source switching-controller can be programmed for manual or automatic switching with prioritization among the four sources: 2 GNSS receivers, PTP, and external 10 MHz / 1 PPS reference. Each GNSS receiver supports all the major satellite systems (GPS, Glonass, Galileo, Beidou, QZSS) with programmable constellations for each. Each GNSS receiver has an OCXO for high precision and extended holdover. The PTP module supports IEEE 1588-2008 and all major telecom profiles (G.8261.1, G.8275.1, G.8275.2). The PTP can be programmed for slave mode, typically backing up the GNSS or master mode, providing network timing to the facility using one of the GNSS as the reference. The distribution module provides twelve 10 MHz and 1 PPS outputs, with the option to increase that number using an external distribution amplifier.
The GNSS-PTP provides excellent operational and management capabilities via Web and SNMP interfaces, as well as 4 General Purpose Inputs and Outputs which are user-programmable.
