Product overview
SymmetricomChip level atomic clock, SA.45s power consumption to <115 mW, its volume is only <16 CC, providing ultra-low power mode of operation settings.In this mode, the physical encapsulation is usually closed. The device operates in a state similar to TCXO free oscillation. When the physical package is started regularly, it will tame TCXO (no more than 120s), and the average power consumption under this mode will not exceed 50 mW.For the first time, portable instruments can also have the accuracy and stability of atomic clock level.
Product function
1) It provides a standard 10MHz sine signal.
2) Synchronous 1 PPS input / output;
3) RS-232Management control interface.
Product characteristics
A) Ultra low power saving mode, <100 mW;
B) Totally enclosed package;
C) Super small volume, high reliability.
Typical application
1) Underwater sensor network;
2) GPSReceiver;
3) Knapsack radio;
4) Anti explosive device (Anti-IED) jamming system;
5) Independent sensor network, pilotless aircraft and so on.
