SITIME Corp

Overview

SiTime Corp. is a fabless semiconductor company focused on precision timing solutions for the electronics industry. Its products include silicon MEMS oscillators, clock integrated circuits, resonators, and synchronization software, serving applications such as AI and datacenters, communications, automotive, industrial, aerospace and defense, mobile, IoT, and consumer electronics.[1] The company describes its mission as solving “the world’s most difficult timing challenges.” [2]

SiTime reported FY2025 revenue of $326.7 million.[3] Its 2025 sustainability report lists 441 full-time-equivalent employees across 13 countries as of December 31, 2025, reflecting an international operating presence.[4] [1]+3

Products & services

SiTime’s products are silicon MEMS timing components: resonators provide a frequency reference; oscillators combine a resonator with circuitry to generate and sustain a clock signal; and clock ICs use PLLs, dividers and drivers to produce multiple clock outputs. Its offerings include XOs, VCXOs, DCXOs, temperature-compensated oscillators, Super-TCXOs, OCXOs, network synchronizers, jitter cleaners, clock generators and buffers.[5]+4

Product platforms include Elite, Elite X and Elite RF Super-TCXOs, Endura ruggedized timing products, Cascade clock ICs, and Titan MEMS resonators.[10]+4 The products serve communications and data-center systems, automotive and industrial equipment, aerospace and defense, and mobile, IoT and consumer devices.[15]+4

The company highlights programmable frequencies, temperature stabilization and resilience to vibration, shock, temperature gradients, airflow, electromagnetic energy and power-supply noise; low-power options include NanoDrive and FlexSwing.[20]+3 TimeFabric is synchronization software described as IEEE 1588-compliant; SiTime says its software is embedded in offerings rather than sold separately.[24][25] The company reports revenue primarily from product sales, but the FY2025 filing does not provide revenue percentages by product family.[26] [5]+21

Geographic presence

SiTime’s principal executive office is in Santa Clara, California. It leases office space in California, Michigan, Malaysia, Japan, Taiwan, the Netherlands, Finland, Ukraine and India.[27]+2

The company conducts research and development in the United States, Japan, the Netherlands, Taiwan, Ukraine, Finland, India, Canada and China. Marketing and administrative functions are located in the United States, Japan, the Netherlands, China, Taiwan, Malaysia, Ukraine and India; sales personnel are based in various locations outside the United States.[29][30] SiTime outsources manufacturing to third parties, primarily in Germany and Asia; its disclosed fabrication partners include Bosch and Teledyne for MEMS and TSMC and UMC for analog circuits.[30][31]

SiTime reports sales geography by distributor ship-to location rather than by end-customer location: outside-U.S. ship-to locations represented approximately 95% of revenue in Q2 2026 and 94% in the first half of 2026. The company says most end customers are believed to be U.S.-based, based on distributor sell-through information.[30] At December 31, 2025, SiTime had 441 full-time-equivalent employees—239 in R&D, 162 in sales, general and administrative, and 40 in operations—with no employee count by country provided in the cited filing.[27] [29]+6

Business segments

SiTime reports one operating and reportable segment: the design, development, and sale of precision timing solutions to the global electronics industry. The company’s management evaluates performance and allocates resources on an aggregate basis, so approximately 100% of reported revenue falls within this single segment.[32][33]

Applications such as AI infrastructure, communications, automotive, industrial, aerospace and defense, and mobile, IoT, and consumer devices are described as markets for its products, not as separately reported segments. SiTime does not disclose revenue percentages by these applications, so their individual contributions cannot be estimated from the cited reporting.[34] [32]+2

Company history

SiTime was incorporated in Delaware on December 3, 2003, and began operations in 2005. Founders Markus Lutz and Aaron Partridge developed its MEMS timing technology; SiTime reports that its products began appearing in end products in 2008.[35][36] Rajesh Vashist joined as CEO in September 2007.[37]

The company introduced its SiT15xx family of 32 kHz MEMS oscillators for mobile devices in March 2013.[38] In 2014, MegaChips agreed to acquire SiTime for $200 million; the transaction closed in November, making SiTime a wholly owned subsidiary.[39][40] SiTime later began sampling clock ICs in 2019 and completed its IPO that November, with its stock trading on Nasdaq.[41][42]

In 2020, SiTime introduced its Cascade MEMS clock IC family for 5G, telecom and datacenter applications.[43] In 2023, it expanded into aerospace and defense with the Endura SiT7910, then agreed to acquire Aura Semiconductor clock products and license related IP; that acquisition closed in December 2023.[44]+2 In 2026, SiTime agreed to purchase certain assets of Renesas’ timing business and reported completing the acquisition on July 1.[47][48] [35]+13
