She has reported on TikTok since its introduction … WebThe first issue is the clock jitter. The clock is generated from general purpose digital logic and is (at least initially) routed through general fabric routing resources. The power grid to the fabric has noise on it from all the digital logic switching, which gets coupled into your generated clock causing jitter.
