Figure 79. ADRV9001 Provided Timing Parameters and the System Clock for the Selected Profile in TES
Based on the information provided in
Default Timing Parameters for Transmit Channels
Figure 80
shows the ADRV9001 transmitter's required timing parameters and their minimum, maximum, and default values, and
summarizes some recommendations.

91 ms/scaleFactor
Default = min
91 ms/scaleFactor
Default = min
Not needed if not controlling LNA power.
91 ms/scaleFactor
Default = min
Can increase to non-zero if performance degrada-
tion is observed, and the channel is transmitting
for some time before the start of the actual frame
(forced to 0 currently by the ADRV9001).
91 ms/scaleFactor
Default = min
Can increase if performance degradation is ob-
served, and the channel is transmitting for some
time after the end of the actual frame (forced to 0
currently by the ADRV9001).
enableHoldDelay +
Default = max
propagationDelay
Can decrease if not all data sent through interface
must be transmitted.
