* Arbitrary frequencies available

 

Notes:
(1) Typical power level at least 1 dB higher than minimum.  Higher power level available.
(2) Lower spurious option available. 
(3) Other Reference Frequencies to be specified by customer, contact factory for details. 
(4) Guaranteed phase noise is 5 dB higher than typical.
(5) Wider temperature range available.
(6) Other supply voltage available.
Unit performances frequently meet or exceed typical level.

Applications: High stability, very low phase noise crystal reference source.  To be used as "Add On Reference Module" to all phase locked sources using an external reference, or as intermediate reference sources phase locked to lower frequency standards.  Mounting hole patterns compatible to general industry phase locked oscillators.
