LMK1C1102: Residual Phase Noise Plot for the LMK1C1102

Mark Hughes

Part Number: LMK1C1102

The datasheet has the plot below., but I am interested in the actual 1/f corner and absolute noise floor for the part. Do you have a plot when driven by a high quality Wenzel OCXO at 100MHz?

Hi Mark,

We can provide that plot. It would require some time to capture it in the lab. I need to check EVM availability in our lab. I will get back with an update by this Thursday.

Best,

Asim

HI Mark,

Here are plots for LMK110X family at 100 MHz for 1/f noise. I have used SMA100B Rhode and Schwarz as input source which is better than Wenzel crystal in my experience.
