UCD3138: UCD3138 CLA DELAY ONE MORE QUESTION

Part Number:UCD3138

Hi Sir:

We update the event As soon as Filter calculation is done, while we found Pulse extension issue;

Yitzhak Bolurian once said that The delay for the CLA (between SAMPTRIG and Filter Output) is about 450 nS. For UCD3138 the event update window is by default 75 nS from the start of period.

we set SAMPTRIG and output clamp high by taking all this into consideration; we can sure if CLA delay is 450ns, Event update window is 75ns, there is no chance that moving edge of DPWM would go into event update window;

we adjusted the SAMPTRIG and found the CLA delay was around 250ns; is there any way we can measure the CLA delay directly to confirm this?
