Figure 80. Timing Parameters Configuration in TES
Figure 80 shows that only relevant channels are enabled to configure the timing parameters. Enter all the values in ns. The propagation delay is
a helper parameter, which is not needed by the ADRV9001. It helps to set the other timing parameters for the ADRV9001.
As previously mentioned, use the API command adi_adrv9001_Radio_ChannelEnablementDelays_Configure( ) to set the timing parame-
ters. For more details, refer to the API Doxygen document.
Pin Control Mode Timing Measurement
The ADRV9001 receives transmitter/receiver enable control signals and related timing parameters to perform the transmitter/receiver RF On/Off
operation in the pin control mode. As previously mentioned, the enableSetupDelay (EnaSetup) is the time taken for the ADRV9001 to power up
its AFE, and the ADRV9001 also takes less time to finish the operations to power down its AFE at the falling edge of the transmitter/receiver
enable signals. It is advised that the programmable "EnaRise2AnaOn" and "EnaFall2Off" delay the ADRV9001 analog components power
on and off, respectively. The enableSetupDelay varies with different ADRV9001 internal processor clock rate (System Clock). Enable the
ADRV9001 internal stream status to GPIO debug function to accurately measure the transmitter/receiver enable control signal and when they
are actually taken effective by the ADRV9001 internal stream processor.
