$SITM supplies timing devices used in optical modules in NVIDIA-based AI data centers. In an AI data center, a clock exists to keep parts synchronized. Training and inference run across thousands of chips in parallel, and each step depends on data arriving at the right moment. When timing slips, GPUs wait, networks stall, and expensive compute goes unused. The move from 800G to 1.6T optical modules shows how this becomes demand for timing parts. Bandwidth does not simply double. The link is split into more lanes running at higher baud rates. Each lane has a tighter jitter budget, and it often adds clock domains for the DSPs, SerDes groups and laser drivers. So each module carries more timing components, and each component has to meet a higher performance requirement. That pushes average selling prices up alongside unit volumes. The same pattern appears in the switches inside that cluster. A high-radix switch multiplies SerDes lanes as bandwidth scales. When the switch increases radix and speed at the same time, it drives more clock domains across the fabric, the ports, and the control logic. Timing content in the switch therefore multiplies rather than rising in step with the size of the cluster. This is why we see continued hypergrowth for SiTime. In NVIDIA-based data centers, SiTime's parts are discrete devices, separate from the GPU and switch ASICs, allowing timing performance to improve independently as system requirements change, and demand for them rises in several places in the rack at once.

Secular theme of increasing competition in the coffee space, no issue taking a position against SBUX which still carries a premium valuation largely on that premise. My flip side to that, is why also be long Dutch $BROS? Trades worked against you for almost the same reasons - intensifying competition from direct copy cat 7 Brew. But there are many regional players that are aggressively scaling - Summermoon, Foxtail, Lala land, Merrit, etc and those are the ones just geographically close to me but it's a countrywide phenomenon. Turns out yes coffee is habitual and generates good cash returns, but barriers to entry are low. The bidding war for the Salads real estate was insane, and shows how deep pocketed 7 Brew is in their expansion, and being PE backed and not public means they might be less disciplined...... So why Bros? There might still be potential there, the model is efficient and a cult service culture, but even at current levels I find the valuation difficult to digest not to mention overhangs from GLP1s, affordability/gas prices
