SiTime Corporation announced the launch of its Elite 2 Super‑TCXO, a silicon MEMS timing solution engineered to enhance GPU utilization in artificial‑intelligence data centers. The new product targets the growing demand for high‑precision clocking in 1.6‑terabit optical modules and AI server infrastructure, positioning SiTime at the core of the AI infrastructure buildout.
The Elite 2 Super‑TCXO delivers sub‑nanosecond synchronization—10 times better than the current 1‑microsecond target—enabling data‑center operators to run GPUs at higher clock speeds without compromising reliability. By tightening cluster‑wide timing, the device addresses the hidden tax of low GPU utilization that can reach 20‑40 percent in AI clusters.
The launch follows SiTime’s September 17 2025 introduction of the Titan resonator platform and the February 4 2026 announcement of its acquisition of Renesas Electronics’ timing business. The Renesas deal is expected to add roughly $300 million in revenue with about 70 percent gross margin, and three‑quarters of that revenue is tied to the AI‑data‑center‑communications segment, further expanding SiTime’s product portfolio and customer base.
SiTime aims to capture a share of the projected $1.5 billion timing market for AI workloads by 2030. The Elite 2 Super‑TCXO positions the company to meet the critical need for sub‑nanosecond synchronization in AI data‑center clusters, complementing its broader MEMS strategy to replace traditional quartz components.
Q4 2025 revenue reached $113.3 million, up 66 percent year‑over‑year, with non‑GAAP EPS of $1.53, beating analyst estimates. The Communications, Enterprise and Data‑Center (CED) segment generated $64.6 million in revenue—160 percent higher than a year earlier—and accounted for 57 percent of total revenue. Management highlighted strong demand and operational leverage as key drivers of the performance.
For Q1 2026, SiTime guided for EPS of $1.10 to $1.17 and revenue of $101 million to $104 million, exceeding consensus estimates and reflecting confidence in continued demand. Rajesh Vashist said, "Driven by AI, Q4 2025 was the seventh consecutive quarter of over 100% year‑over‑year growth for our Communications, Enterprise and Datacenter (CED) business." Piyush Sevalia added, "Industry reports show GPU utilization in AI clusters can be as low as 20 to 40 percent—a large and largely hidden tax on AI infrastructure." Beth Howe noted, "Q4 was a milestone quarter for the company as we surpassed $100 million in quarterly revenue for the first time and generated operating margins of 30%."
