I would like to use the adf7242 for a sensor application.
my task is to transmit 16bit sensor data every 100us without buffering the data
is this possible with adf7242 (for example in sport mode..)
You can use the SPORT mode to send data without buffering. Normally at the start of the transmission you would have some preamble before your data to allow settling for example of the AGC(automatic gain control) on the receiver side before the data arrives.
