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.

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.
