Speedgoat IO33x-07 Interface
Speedgoat IO33x-07 Interface — Front interface with 16x 16-bit analog outputs
Supported Modules
IO332-200k
IO333-325k, IO333-410k
Reference Design Parameters
Be sure to select "-07" as your reference design's front plugin using the pulldown
menu at step 1.2 of the workflow advisor so that the appropriate interfaces will be
available in step 1.3 of the workflow.
D/A Interface
D/A Output Channel [0:15]
The IO33x-07 I/O module features 4 LTC2755 D/A converters, providing a total of
sixteen 16-bit channels. The IO33x-07 writes in sequences: each write of an active
channel consumes four FPGA ticks, whereas an inactive channel consumes only one FPGA
tick. There is a constant overhead of six ticks when the D/A Group
Trigger
is detected and all the channels are updated. Therefore, if all
the channels are active, all the channels will be updated 70 ticks after the rising
edge of the D/A Group Trigger
.
Data Type: int16
Direction: output
D/A Group Trigger [0]
This port can trigger all 16 channels simultaneously. The trigger port is
level-sensitive, meaning that if a constant high is applied to the port, the D/A
converters are updated with the maximum frequency. To obtain a synchronized setup,
model the D/A Group Trigger
with ideally a single clock pulse of the
FPGA target frequency. In addition, the generation of the required D/A signal must
be synchronized with the D/A Group Trigger
signal. If not, you might
encounter a jitter of one D/A Group Trigger
cycle.
