AWR1243: How to calculate ADCTransferTime in chirp RampEnd time?

Adam Yao94020

Part Number: AWR1243

HI champion,

We find below formula:

The RampEndTime is made up of

ADC Valid Start Time + ADC SamplingTime + ADCTransfer Time

About ADC transfer time, do you have a straightforward equation on how to decide it?

Thanks,
Adam

Hello Adam,

There is no hard requirement/equation to derive the excess ramping time/ADC Transfer time.

The excess ramp time is dependent on the IF/DFE filtering latencies which are function of the DFE output and ADC sampling rate.

The typical DFE filtering latencies as function of DFE mode and output sampling rate are provided in "Programming Chirp Parameters in TI Radar Devices".

Thanks,

Raghu
