Hello Team,

I can find a 0.022uF cap between the reserved pin 17 and 18. I believe this cap is not populated, however, do you recommend to prepare land for this cap ?

What is this cap for ?

Best Regards,

Hi Kawai-san,
No, the pads for the cap is not needed, the landing pad on EVM was in case we needed to have an external cap.
The cap is for the VCO loop filter voltage and LMH1218 device has the cap inside.

Regards,
Michael
