Forum Post: RE: ADS8363: CONVST relative to CLOCK
Hi Ian!The sampling instance for the ADS8363 is not actually dependent on t1 from the standpoint of the CLOCK input. The t1 setup time is related to the point at which the conversion actually begins -...

Thank you, Tom.So, just to be clear, there are no internal metastability issues in ADS8363 with missing t1. Transition to hold occurs on the rising edge of CONVST regardless of the state of CLOCK....

Meenakshi,I do not believe there is a direct way to do so on the TSW30Sh84/TSW1266. You will need to implement this feature on your FPGA setup or on our TSW1400's. When operating with the TSW30H84, the...
