Hello,
we are using more than one of this ICs in our design and need to know how the timing is differing between them.
- Jitter Values
- Temperatur dependencies
In the Datasheet, I do not find any information about this.
Thanks a lot...

Bo Wang4 said:For jitter values, do you mean PWM/Vsw jitter? if yes, it depends the controller operation.
CSD97395Q5M propagation delay variation vs. temperature is within few nano seconds.
Hi Wang,
both CSD97395Q4M are controlled from the same PWM (the PCB distance is the same). Now is the question how dose the output (VSW) of both CSD97395Q4M differ from each other and what it depends on?
Can you give me some numbers?
Best regards Adam
Hi,
Do you mean that the same PWM signal was used to control two Power Stages in your design. The PWM to Vsw propagation delay will mainly depend on temperature, VDD voltage, load current and device process variation. I need to check if we have data available and will let you know tomorrow.
Thanks!
Hi Adam,
We don't have data for these ranges, but the variation will be smaller than 15ns(from 25C to 125C).
Thanks!
