Part Number: AWR2243
Dear engineers: Hello! We use four pieces of AWR2243 for cascade design. The working mode of AWR2243 is fixed by resistors. The SOP mode is SOP4, that is, SOP0=1; SOP1=0; SOP2=0; and the VION pin of AWR2243 is set to 1.8V. …

Hi Ritesh,
Ritesh Tewari said: So, numChirpsPerLoop corresponds to each tx in cascaded mode. One chirp for each transmitter.
numChirpsPerLoop doesn't correspond to Tx. You can configure a chirp to be transmitted by multiple tx. Refer to
Programming…
Hi Jim,
Linking previous thread regarding synchronization: https://e2e.ti.com/support/sensors-group/sensors/f/sensors-forum/988354/awr2243-the-synchronization-in-cascade-mode . In the thread, there is also a link to the AWR2243 cascade application note…
Part Number: AWR2243 Hello everyone,
I use hardware trigger to start the frame collection, but after the first frame the received signal becomes very noisy and in some cases the peaks are not clear in the signal FFT. I have the signal connected to pin…
Part Number: AWR2243 Hello,
I am experiencing a similar issue to the one in the referenced post ( AWR2243: Samples decay - Sensors forum - Sensors - TI E2E support forums ) where the samples decay at the end of the chirp. I am using a master/slave configuration…
Part Number: AWR2243 Other Parts Discussed in Thread: TDA2 , MMWCAS-DSP-EVM , MMWCAS-RF-EVM , I'm using TDA2 to capture data and test MIMO mode.
I ran the script Cascade_Configuration_MIMO.lua then called for data capture by script Cascade_Capture.lua Then…
Part Number: AWR2243 In AWR2243, when the master and slave are connected, does the MCU send the trigger signal directly to the master via SPI, and then the master triggers the trigger signal of the slave via hardware, or does the MCU send the trigger…
Hello James,
I still have some questions on the topic:
- are the two outputs FMCW_CLKOUT and FMCW_SYNCOUT work exactly the same?
- and if we only have one slave device, do you know why the system works only if we use just one port and a splitter to have…
Part Number: AWR2243 n AWR2243 cascaded system, slave devices use external frame syn signal for frame trigger and this frame sync signal will route back to host. There is frame trigger delay after sync in pulse input to real frame start (chirp transmit…
