5.3 Phase Noise Performance

Jitter is key performance spec which all clock products are judged against. The LMK6P/D/H BAW oscillator offers great jitter performance meeting 100 fs typical for differential outputs:

The single ended version has best in class jitter performance with typicals below < 300 fs:
