Figure 74. ADRV9001 Provided Timing Parameters and the System Clock for the Selected Profile in TES
Based on the information provided in Figure 74, user can further configure the ADRV9001 required timing parameters.
Default Timing Parameters for Transmit Channels
Figure 75 shows the ADRV9001 transmitter required timing parameters and their minimum, maximum, and default values as well as
some recommendations are summarized in Table 27.

(Not Used Currently)
0 91 ms/scaleFactor Default = min
Can increase to non-zero if performance
degradation is observed and the channel
is transmitting for some time before the
start of the actual frame
(Forced to be 0 currently by ADRV9001).
enableHoldDelay
(t
TxEnaHold
)
(Not Used Currently)
0 91 ms/scaleFactor Default = min
Can increase if performance degradation
is observed and the channel is
transmitting for some time after the end
of the actual frame
(Forced to be 0 currently by ADRV9001).
enableFallToOffDelay
(t
TxEnaFall2Off
)
enableHoldDelay enableHoldDelay +
propagationDelay
Default = max
Can decrease if not all data sent through
interface must be transmitted.
