GatesAir Maxiva GNSS1U-PTP

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.Main Features:Compact 1RU 19 Rack chassisOptional double redundant GNSS receiver modules with fast signal acquisition, and back-up batteriesExtended hold over with OCXO12 separate 10 MHz outputs and 12 separate 1 PPS outputsOptional hot-swappable and redundant power supply units (AC+AC, AC+DC, or DC+DC) with battery backupOptional hardware PTP module for IEEE 1588-2008 capabilitiesSecure Web interface and Secure SNMP managementFront panel display with status LEDsRemote control and GPIOSpecifications:Frequency and Time Reference Sources and Selection:GNSS A: IncludedGNSS B: OptionalPTP: OptionalExternal 10 MHz/1PPS: IncludedSource Selection: Automatic with user-defined priorities; ManualFrequency Reference:Output Signals: 10 MHz sine waveOutput Level: -5…+10dBm into 50 ohm load, user adjustableNumber of Outputs: 12 independentOutput Impedance: 50 OhmOutput Connectors: BNC (f)Noise Figure: 100 Hz -140 dBc/Hz, typicalNoise Figure: 10 kHz -150 dBc/Hz, typicalStability: 1e-12 daily average with disciplined OCXOInitialization Time: < 4 minuteTime Reference:Output Signals: 1 PPS, 2.5-4 V p.p.
