88W8987 RF Front-End Control Interface

Hello,

I am looking for information on the 88W8987 RF Front-End Control Interface. The datasheet shows that it is composed of 4 outputs. It has electrical specifications for the outputs, but I can't find information about the function of each output.

I am interested to know if any of these outputs can control an external Tx/Rx switch. Also, is there any timing info about these control lines? I am interested in timing between the RF controls and Wifi traffic.

Thank you very much,

Justin

Hello @jbuttelmann

You could refer to reference design for control logic and wire connection. If you use different FEM structure, we have calibration file to adjust FEM control logic. You need submit ticket to us for your specially needs.
