AFE7769DEVM: AFE7769D - Transmission timing synchronization

Part Number: AFE7769DEVM
Other Parts Discussed in Thread: TSW14J58EVM

Tool/software:

Hello,

Is there a function in the TSW14J58EVM that generates a trigger signal to synchronize an external PA with the TX timing of the AFE7769DEVM?

Am I correct in understanding that TRIG_IN is used to input a trigger signal from outside to synchronize the RX?



SYNCA, SYNCB, and SYNCC are output signals, but under what conditions are the signals output?

Can they be used to synchronize the TX timing?

Best regards,

Kazuto Odajima

    Hi Kazuto-san,

    I think you are inquiring about the TDD synchronization. TSW14J58EVM can support trigger signals through TRIG_IN and SYNCB. Right now, our current TSW14J58 setup is not convenient for our customers to use to synchronize. Therefore, we are not ready yet to release the solution to our customers. Our goal is to release a simpler hardware/firmware packages on TSW14J58 by 2025 to allow the evaluation of the TDD control.

    Thanks,
