AWR2243: AWR2243 sample rate limitations

Sagi Sheer
Prodigy 70 points
Part Number: AWR2243

Hello,

I am using the cascade board with four AW2243 chips.

When I config the Sample rate to be 30Msps (or 30000 ksps) in the mmWave studio, I get the following error:

[12:28:20] [RadarAPI]: ar1.ProfileConfig_mult(15, 0, 76, 5, 0, 60, 0, 0, 0, 0, 0, 0, 40.217, 0, 1024, 30000, 0, 0, 30)
[12:28:20] Status: Failed, Error Type: SAMPLING RATE IS NOT WITHIN [2, 37.5] Msps
[12:28:20] Profile Configuration failed

Why I get this error? 30Msps is inside the range [2,37.5] Msps.

Thanks,

Sagi.

    Hi,

    Since you are using a cascade design, I think you are using AWR2243P not AWR2243

    As mentioned in the datasheet, Table 6-1 Device Features Comparison

    for complex 1x sampling rate the max is half

    Thank you
