DATACONVERTERPRO-SW: About TriggerCLKDelays in AutomationDLL

Part Number: DATACONVERTERPRO-SW
Other Parts Discussed in Thread: TSW14J57EVM

I found the 'TriggerCLKDelay' option in AutomationDLL.

We are considering starting data acquisition by inputting a synchronization signal into the TSW14J57EVM.

Can we use 'TriggerCLKDelay' to initiate data capture after a certain number of milliseconds have elapsed since the synchronization signal is received?

  • Hi Ryota,

    As mentioned in other post, yes, this is an 8-bit field and refers to # of reference clock periods. You will not be able to delay by milliseconds however due to 8-bit limit. For example, with reference clock of say 50MHz (which is very low and likely lower than the ref clock required for your particular mode), 255/50MHz = 5.1us. The reference clock would have to be in kHz range for this to work which is not an option. Instead, it would be better to adjust the trigger output which you are using to account for this delay. When the trigger is received, if the FPGA is "armed", then the data will be saved.
