Digital Instruments NANOREF time & frequency reference 1 Overview Nanoref is the best cost effective Time & Frequency solution to generate ultra stable Time (NTP & PTP IEEE 1588-2008, TTL customized Time Codes) and frequency (10 MHz, 2.048 MHz, E1 synchronization signals). Furthermore the unit is managed via SNMP or via a user friendly GUI on web Interface. The units is a multi reference input equipment that can accept PTP Time Protocol E1 synchronization signals and 2.048 MHz as well as GPS The unit is available as OEM board ready to be integrated on OEM equipments or as stand alone with 1U/19” chassis ready to be integrated on 19” rack. Due to the ultra stable dual Oven OCXO, Nanoref provide high level performance in terms of Holdover and in terms of Phase Noise on frequency output. Internal high stability OCXO aging rate of ± 1*10 -10 /day 12 channels GPS receiver with automatic tracking and timing error management system. New generation DPLL fast lock Multi reference inputs 1x Ethernet interface for NTP and/or PTP synchronization 1x 10 MHz Low Noise output /2.048 MHz/E1(T1) with SSM input, Customized TTL Time code output 1 x 1 PPS output Size: 1U/19” – depth 300 mm (connector excluded) – weight 1,5 Kg Certification CE.
