Hi TI,

We are working on IWR6843 sensor module board design.
What's the recommended land pattern for this module.The datasheet provides two different land patterns ABL0161B & ABL0161A.

Schematic balls matches with only ABL0161B.
Kindly suggest.

Hi Charles,

Thanks for the information.

In the IWR6843 datasheet ball no A13 has assigned to two different signal name VSSA(ground) and VOUT_14SYNTH(supply).Which one is the correct one?

Hello,

Thank you for pointing out.
A13 is VSSA, B13 is for the VOUT_14SYNTH. This would be corrected in the next version of datasheet.

Thanks and regards,
