LMK1D2102: phase noise at 20Hz~1kHz

Noriyuki Takahashi

Part Number: LMK1D2102

Hi team,

Custmer wants to understand the phase noise at 20Hz~1kHz, while we can see the phase noise result at the over 1kHz according to Figure 10-4 of the datasheet.

Could you please show the phase noise result at 20Hz~1kHz?

Regards,

Hello Noriyuki,

Could you tell me what output frequency the customer is using? Is it 156.25-MHz?

Best,

Andrea

Noriyuki ,

I have attached captures of the phase noise results from 20Hz~1kHz for the reference input we used and output for a LMK1D2102 that you requested.

Here is our reference input at 100 MHz generated from a SMA 100A.

Here is the LMK1D2102 output.

Regards,

Will
