left-justified and padded with 4 zeros in the LSBs. You must rout DStarA to the CLIP
from LabVIEW FPGA. The data is clocked out of the CLIP on Data Clock.

the NI 5752/5752B with a socketed CLIP, and for a list of available socketed CLIP signals.
Clocking
The NI 5752/5752B clock source controls the sample rate and other timing functions on the
device. The following table contains information about the possible NI 5752/5752B clock
sources.

Sync Clock
(DStarA)
Sync Clock (DStarA) is only available on NI PXI
Express FlexRIO FPGA modules (such as the
NI PXIe-796xR). DStarA is not available on
NI-793xR controllers for FlexRIO or NI PXI FlexRIO
FPGA modules (such as the NI PXI-795xR). On PXI
Express modules, Sync Clock is driven by the DStarA
from the PXI/PXIe backplane.
If you change the frequency of Sync Clock (DStarA)
or CLK IN (when used as the Sample Clock), you
must assert Force Initialization.

If you change the frequency of Sync Clock (DStarA)
or CLK IN (when used as the Sample Clock), you
must assert Force Initialization.
