*Lower frequency phase locked oscillators (300 - 3000 MHz) offered in similar performance.
** Higher frequency phase locked oscillators (18 to 23 GHz offered in similar performance.

 

Notes:
(1) Typical power level at least 1 dB higher than minimum.  Higher power level available.
(2) Lower spurious option (<-85 dBc) available. 
(3) Other Reference Frequencies to be specified by customer, contact factory for details. 
(4) Guaranteed phase noise is 5 dB higher than typical, with acceptable Reference Noise Floor 

     Typical phase noise within loop bandwidth= 20 Log (N) + 3 dB, N is the Reference Multiples.
(5) Wider temperature range available.
(6) Other supply voltage available, 550mA surge current at cold.

Unit performances frequently meet or exceed typical level.

Applications: PLDRO's have the best combination of ultra low phase noise and excellent frequency accuracy when phase locked to an ultra stable 10 MHz SC cut crystal reference.  Dual Loop PLDRO's are ideal for high data rate 64 QAM and 128 QAM digital communication systems in LMDS, MVDS, point to point digital radio transceivers, and Fiber Optic applications.  The NXPLOS-IX series provide excellent phase noise in a compact size with  unmatched frequency stability.  to Products Page
