STEP 6: OPTIONAL ERROR MONITORING
For JESD204B error monitoring, see the JESD204B Error
Monitoring section. For other error checks, see the Interrupt
Request Operation section.
STEP 7: OPTIONAL FEATURES
There are a number of optional features that can be enabled.
Table 22 provides links to the sections describing each feature.
These features can be enabled during the digital datapath
configuration step or after the link is set up, because it is not
required to configure them for the link to be established, unlike
interpolation. Unless otherwise noted, these features are paged
as described in the Dual Paging section. Paging is particularly
important for dual specific settings like digital gain, phase adjust,
and dc offset.

Feature
Default Description
Digital
Off
Modulation
Modulates the data with a desired
carrier. See the Digital Modulation
section.
Inverse Sinc
On
Improves pass-band flatness. See
the Inverse Sinc section.
Digital Gain
2.7 dB
Multiplies data by a factor. Can
compensate inverse sinc usage or
balance I/Q amplitude. See the
Digital Gain section.
Phase Adjust
Off
Used to balance I/Q phase. See the
Phase Adjust section.
DC Offset
Off
Used to cancel LO leakage. See the
DC Offset section.
Group Delay
0
Used to control overall latency. See
the Group Delay section.
Downstream
Off
Protection
Used to protect downstream
components. See the Downstream
Protection section.
Self Calibration Off
Used to improve DAC linearity. Not
paged by the dual paging register.
See the Self Calibration section.
