Low Phase Noise OCXOs 10 MHz, phase noise down to -115 dBc/Hz @ 1Hz / -146 dBc/Hz @ 10 Hz XO5123 Series FEATURES SOLID FOUNDATION Stress compensated crystal cut -12 High stability – 5 x 10 Allan deviation Low aging – ± 0.1 ppm/year Precision measurement and reliability communications need a solid reference Ultra-low phase noise Standard -140 dBc/Hz @ 10 Hz -169 dBc/Hz floor Low -145 dBc/Hz @ 10 Hz -170 dBc/Hz floor Ultra -115 dBc/Hz @ 1 Hz -146 dBc/Hz @ 10 Hz -172 dBc/Hz floor Sine output Oven monitor, enable, low g-sensitivity options Thru-hole Europack – 36 x 27 mm APPLICATIONS Lab instrumentation Satellite communications Radar COTS Copyright © 2014 MtronPTI. All rights reserved. Network analyzer measurements are only as good as the noise they themselves generate. Satellite communication terminals and radar need low noise to hold the channel and provide a clear image. MtronPTI’s XO5123 Series Low Phase Noise OCXOs bring the ultra-low phase noise and high stability these systems need. In the near past, low noise reference oscillators were bulky multicubic-inch boxes, perhaps designed by system builders themselves. No more. MtronPTI’s XO5123 Series delivers down to -115 dBc/Hz @ 1 Hz and -172 dBc/Hz noise floor in a small, 36 x 27 mm, ‘Europack’ package. Consuming only 2.5 Watts steady state and with ± 0.1 ppm/year aging, the XO5123 Series also meets SWaP (low size, weight and power) requirements as well as ensuring long, accurate equipment life. Nearly fifty years of crystal science and high performance oscillator design and manufacturing helps MtronPTI’s XO5123 Series make measurements a bit more accurate, data links more reliable and situational awareness more complete.
