Part Number: AWR1243
I am designed a cascaded radar with 2 AWR1243 (one is Master and other is Slave). Each AWR1243 is powered by 4 LDO and the PMIC not used.
The pins that are connected to 60-pin connector are:LVDSs (Data[0-3], CLK, Frame CLK, Valid), SPIs( CS, MISO, MOSI, CLK), Host INTR(p6), NRST_MCU and NERR_OUT(N8) and there is no other connection to outside in the cascaded AWR1243.
I want to design an Capture card like DCA1000EVM Kit.Are the connected pins sufficient for proper radar functionality?
For digital frame synchronization, I got an output from SYNC_OUT(P11) and gave it to SYNC_IN pins( N10) on both of Master and Slave with equal length.In DCA1000EVM Kit, SYNC_IN pin of AWR1243boost is connected through DMM_MUX_CTL.Duo to synchronization done, Is it necessary to connect SYNC_IN to Capture card? or is it necessary to connect SYNC_OUT to Capture card?
Pins of MCU_CLKOUT(N9) and WARM_RESET(N12) of AWR1243boost are not connected to DCA1000EVM. Does not create disrupting in programming and functionality of cascaded AWR1243 without connecting of these pins?
We are glad that we were able to resolve this issue, and will now proceed to close this thread.

Thanks for your attention.
1-When will your cascaded system be publised?
2-So you confirm that, it is not necessary connect SYNC_IN (N10) and SYNC_OUT(P11) to capture card, and only needed got an output from SYNC_OUT(P11) of Master and gave it to SYNC_IN pins( N10) on both of Master and Slave with equal length?
3- AWR1243p?? about AWR1243p it is not mention in datasheet (SWRS188 –MAY 2017) and document cascading (SWRA574–October 2017)
The part number that we bought is X1243BIGABL. Does this part number support cascading?
In reply to tom daglas:
Thank you for the response. I have another question that is your datasheet reliable? because we have bought the X1243BIGABL based on the datasheet (SWRS188 –MAY 2017, page 4) that is attached, in which you mentioned the IC supports cascading but in 2018 version (oct.10,2018) is said the ic does not. So, what should we do now? swrs188.pdf
Do you answer my question??
Thanks. I am waiting for your answer
