Peering Over the Timing Edge

Peering Over the Timing Edge
by Bernard Murphy on 05-03-2018 at 7:00 am

I wrote recently about a yield problem which mobile vendors have been finding for devices built in advanced technologies. This was a performance issue (the devices worked fine at lower clock speeds), pointing to a discrepancy in some devices between predicted and observed timing. These were experienced design teams, using state… Read More


Understanding Sources of Clock Jitter Critical for SOC’s

Understanding Sources of Clock Jitter Critical for SOC’s
by Tom Simon on 05-29-2017 at 12:00 pm

Jitter issues in SOC’s reside at the crossroads of analog and digital design. Digital designers would prefer to live in a world of clocks that are free from jitter effects. At the same time, analog designers can build PLL’s that are precise and finely tuned. However, when a perfectly working PLL is inserted into an SOC, things can … Read More
