Part Number: LMK61PD0A2
Other Parts Discussed in Thread: TPS7A8300

Tool/software:

Hi,

We are using LMK61PD0A2 Oscillator which is supplied 3.3V FROM TPS7A8300ARGRR IC.

We have checked voltage and current requirements of TPS7A8300ARGRR which is sufficient for the Oscillator.

Apart from this, Is there any other parameter we should check to ensure proper working of the oscillator?

Hi Narender,

If you have a particularly noisy input source you could look into using an LDO with better PSRR, but I think TPS7A8300 should be fine for most applications. I would also recommend reading the power supply filtering recommendations from section 11 of the LMK61PD0A2 datasheet if you haven't already. Let me know if you have any other questions.

Regards,

Connor
