AWR2243: SOP PIN setup and SPI connection

AWR2243: FM_CW_SYNCOUT termination for AWR2243P single use

Part Number: AWR2243

Hi,

Could you kindly let me double-check the termination of FM_CW_SYNCOUT and FM_CW_SYNCIN1 & 2 in the case of AWR2243P?

In the AWR2243 on the BOOST,  the FM_CW_SYNCOUT pin is open and the FM_CW_SYNCIN1 & 2 are both connected to GND.

My understanding is that AWR2243P is supposed to be used for cascade configuration originally.

So my question is whether if the above AWR2243 termination for these 3 pins is also available for the case of AWR2243P single use.

Your advice is greatly appreciated.

Best regards,

Masayuki

    Hello Masayuki,

    Yes, the above signals are only applicable for cascade devices. In case of single chip boost EVMs, all of them have AWR2243P silicon where FM_CW_SYNCOUTCLKOUT pins are open and the FM_CW_SYNCIN1 & 2 are both connected to GND.
