EOS Optronics has developed special modules to be integrated as the basis of state-of-the-art timing systems. The low noise ultra-stable electronic frequency multiplier modules, 10-200MHz and 10-80MHz, are designed to generate unique low jitter frequency signals out of a 10MHz frequency normal. The signal purity (sub-harmonic attenuation of -110dBc) and the sub-picosecond jitter make the time base suitable for high performance timing applications, for example in satellite laser ranging with sub cm ranging accuracy. The ultra-stable 80MHz or 200MHz ECL multiplied complementary outputs are designed to fit the most accurate timing systems available. Other custom specified frequency outputs are available upon request.
