Rubidium, Chip Scale Atomic Clock (CSAC) and Ovenized Oscillator (OCXO) The output signals for the M212 are generated by up to 6 Output Signal Modules (OSM), and are ideal for custom solutions or future expansion. Available modules include NTP, low-phase-noise frequency, time code modules such as IRIG A, B, G, H, and NASA 36, BCD, PPS, PPM, Have Quick, serial data (RS232/422) as well as optical crosslink.
1.1 Master Clock System Basic Concept The Master Clock System is a master clock that can have its capabilities defined by the use of standardized modules, allowing custom solutions to be created from standard hardware. Through the use of these standardized modules, distributed timing networks for high accuracy applications may be readily created.
