SiTime Corporation has entered into a definitive agreement to acquire key assets of Renesas Electronics’ timing business, a transaction that significantly reshapes the precision timing landscape for data center, communications, and AI-driven infrastructure.
The acquisition, announced on February 4 in the United States and February 5 in Japan, values the Renesas timing assets at $1.5 billion in cash along with approximately 4.13 million shares of SiTime common stock. Both companies said the deal has been unanimously approved by their boards and is expected to close by the end of 2026, subject to regulatory approvals and customary closing conditions.
SiTime said the acquired timing business is expected to generate approximately $300 million in revenue in the 12 months following the transaction’s close, with gross margins of about 70 percent. Nearly 75 percent of the revenue is derived from AI, data center, and communications applications, while the remainder comes from industrial and automotive markets.
The transaction expands SiTime’s scale and product reach, positioning the company as a larger pure-play supplier of precision timing solutions. SiTime said the acquisition increases its clocking product portfolio more than tenfold and accelerates its progress toward $1 billion in annual revenue. Following the deal, applications tied to communications, enterprise, and data centers are expected to contribute more than 60 percent of the company’s revenue.
The Renesas timing business brings a 30-year operating history and a customer base of more than 10,000 companies worldwide. Its product portfolio includes clock generators, buffers, network synchronizers, and jitter attenuators, components that are widely deployed in networking equipment, data center switches, routers, and emerging AI systems.
Renesas Chief Executive Officer Hidetoshi Shibata said the transaction allows the company to sharpen its strategic focus on embedded computing while ensuring continuity for customers that rely on its timing products. As part of the broader agreement, SiTime and Renesas have also signed a memorandum of understanding to explore the integration of SiTime’s MEMS resonator technology into Renesas’ embedded computing products.
SiTime’s MEMS-based Titan resonators are designed to be integrated directly with microcontrollers or system-on-chip devices at the package or die level. According to the companies, this approach can reduce board-level complexity, save space, and improve power efficiency. Potential applications include AI data centers, industrial automation equipment, advanced driver-assistance systems, robotics, and wearable devices.
Rajesh Vashist, chairman and chief executive officer of SiTime, said the acquisition strengthens the company’s ability to address increasingly demanding timing requirements in high-performance systems. He added that the deal builds on SiTime’s existing financial performance and supports long-term growth in markets where synchronization accuracy and reliability are becoming critical.
From a financial standpoint, SiTime expects the acquisition to be accretive to its non-GAAP earnings per share in the first year following completion. The company said the deal is also expected to accelerate progress toward the upper end of its long-term gross margin target of 60 to 65 percent, while maintaining its annual revenue growth target of 25 to 30 percent.
SiTime plans to fund the cash portion of the transaction using cash on hand and $900 million in fully committed debt financing from Wells Fargo Bank. The company said it expects to reduce leverage to below two times within 24 months after closing. The transaction is not subject to financing conditions.
Following the completion of the deal, Renesas CEO Hidetoshi Shibata is expected to join SiTime’s board of directors.
Industry observers view the transaction as a reflection of the growing importance of precision timing in AI and cloud infrastructure, where tighter synchronization is increasingly required to support scale, performance, and energy efficiency.
