LMKDB1120: Is LDO integrated into clock buffer?

Part Number: LMKDB1120

Hi team,

Does LMKDB1120 include LDO like BAW oscillator does? If so, my customer can reduce the filter for power supply of LMKDB1120.

Best regards,

Yamamoto-san,

The LMKDB1120 does not feature an integrated LDO.

Thanks,

Michael

Hi Michael-san,

Thank you for the reply. I understood that LMKDB1120 doesn't have the feature of an integrated LDO. Are there TI clock buffers which LDO integrated into?

Best regards,

Shunsuke Yamamoto

Yamamoto-san,

Our current offerings of buffers with integrated LDOs are limited. Our jitter cleaners (LMK048xx series) offer integrated LDOs, but the only buffer with an integrated LDO (which I would not recommend, due to poorer jitter performance) is the CDC3RL02. We have upcoming buffers with an integrated LDO, but currently, following the power supply filtering recommendations in the datasheet is the best course of action.

Thanks,

Michael
