Power Supply Noise Immunity

The LMK6C/D/P/H BAW oscillator integrates internal LDOs which provide the output clock with protection against ripples on the power supply. This adds the benefit of no external LDO or DC/DC converter being needed on the supply to get the best performance out of the oscillator. With a simple bypass capacitor on the supply pin, a majority of the ripple is rejected and does not induce noise on the output.
