XO8085 Integrated Frequency References

XO8085 Integrated Frequency References

Combining over 25 years of discrete RF design expertise and high precision OCXO manufacturing experience, MtronPTI’s XO8085 series provides designers a High Stability, Ultra Low Phase Noise and Low G-Sensitivity PLL OCXO platform with an option of Multi Output Frequency References. With RF systems getting smaller in size an integrated assembly like XO8085 with multi output frequency references, enable system designers to employ one small package with multi frequency references versus multiple OCXOs saving SWaP, cost and improving reliability.

For a 100MHz OCXO phase locked to a lower frequency references like a 10MHz OCXO, the close-in phase noise of the output is determined by the low frequency reference and the phase noise of offset frequencies   greater than the PLL bandwidth is determined by the locked RF oscillator (100MHz OCXO). The XO8085 series provides a noise floor approaching -180dBc/Hz and close-in performance of -130dBc/Hz or better at 100Hz offset.
