MMWCAS-RF-EVM: Mismatch in documentation

Rodrigo Jerez

Part Number: MMWCAS-RF-EVM

Hi,

we are working with the MMWCAS-RF-EVM device and in the user guide we found how the slaves and AWRs# are enumerated:

And in the schematics and layout, we found that the AWRx #3 and AWRx4 are in diferent order. This is a signal connected to the AWRx #3:

And this is other signal connected to AWRx #4:

-Could you confirm us if there is a error in the MMWCAS-RF-EVM user guide?

-If so, could you tell us which is the device refered as slave1, slave2 and slave3?

(We are capturing data with mmWaveStudio and we are now not sure which device is each one).

Thanks!!

Hi,

So the schematic and layout perfectly matches.

In the document also the AWR# is correctly matching. I am not sure what you are trying to indicate as mistake.

The bin file name is exactly matching or mapping to the document.

Hi,

I've drawn with colours the mistmacth:

Schematic and layout for the AWR#3 (cross-probe option in Altium):

Schematic and layout for the AWR#4 (cross-probe option in Altium):

As you can see, in the user guide the numbers of the AWR3 and AWR4 are different from the schematics and layouts in Altium.

We dont know which are correct devices for the slave2 and slave3.

Thank you!!

Hi,

I would recommend to take the marking of secondary devices 2 and 3 form the user guide only.
