AM3352: Clock stability

Ryan T
Expert 3161 points

Part Number: AM3352

Currently using an AM3352BZCZT60 with +/-10ppm stability in my design. Considering moving to a 25ppm clock to solve some constraint problems, but wondered if there was any special consideration about this processor that would prohibit doing so. I see on the datasheet that a +/-50ppm is allowable, but want to make sure that making the change will be feasible and will not come with any added problems. 

Thanks!

    Reference clock stability is partially a function of the AM335x device, but also a function of your system requirements. The AM335x device will not have an issue with a 25 PPM reference clock. You must confirm your system doesn't have any requirements that would be compromised when decreasing reference clock stability from 10 PPM to 25 PPM.
