Speedgoat IO33x-08 Interface — Front interface with 8x 16-bit analog outputs
IO332-200k
IO333-325k, IO333-410k
Be sure to select "-08" 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 Output Channel [0:7]
The IO33x-08 I/O module features 4 Analog Device AD5547 D/A converters, providing a total of eight 16-bit channels. The IO33x-08 writes in sequences: each write of an active channel consumes three FPGA ticks, whereas an inactive channel consumes only one FPGA tick. There is a constant overhead of five 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 29 ticks after the rising edge of the D/A Group Trigger.
D/A Group Trigger
Data Type: int16
Direction: output
D/A Group Trigger [0]
This port can trigger all eight 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.
Data Type: boolean
The pin mapping for the IO33x-08 front plug-in is as follows.
The pin mapping goes with the following terminal board:
