Low Phase Noise OCXOs
10 MHz, phase noise down to -115 dBc/Hz @ 1Hz / -146 dBc/Hz @ 10 Hz
XO5123 Series
FEATURES
SOLID FOUNDATION
Precision measurement and reliability communications
need a solid reference
Stress compensated crystal cut
High stability – 5 x 10-12 Allan deviation
Low aging – 0.1 ppm/year
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.
Ultra-low phase noise
Standard
-140 dBc/Hz @ 10 Hz
-169 dBc/Hz floor
Low
-145 dBc/Hz @ 10 Hz
-170 dBc/Hz floor
In the near past, low noise reference oscillators were bulky multi-
cubic-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.
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
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.
