_**Note #1:**_ Inclusive of initial tolerance at 25ºC±3ºC, operating temperature range, input voltage variation, load variation & 15 years aging at 25ºC. 

_**Note #2**_ :  The rms jitter integrated over 12kHz to 20MHz Bandwidth is dependent on the carrier and whether or not the final frequency is achieved without engaging the Fractional Mode
