TX7316: TR_EN Pin

Hello E2E Experts,

Good day.

I have a question about the TX7316 TR_EN pin. If I use on-chip beamforming, doesn't the level of the TR_EN* pin matter? Is it just the register bits that control its turn-on and turn-off times?

Regards,

    Hi,

    In case of on-chip beamforming, the T/R switch turn on/off is controlled only by the internal digital based on the values programmed in the corresponding registers. The TR_EN* pins in on-chip beamforming are used in the dynamic mode to optimize the power consumption in the device (refer to the section Dynamic Power Mode in the datasheet).

    Thanks and Regards
