History
SiTime was founded in Santa Clara, California in 2005 by researchers Marcus Lutz and Aaron Partridge. [5] [1]
In 2014, the company was acquired for $200 million by Japanese fabless semiconductor company MegaChips. [6]
In 2016, the company launched its Elite platform of Super-TCXOs (temperature compensated crystal oscillators). [7]
In November, the company announced its Emerald line of MEMS timers designed for 5G equipment. [8]
In November 2019, SiTime was spun off and went public. [5] MegaChips is a shareholder that owns 25%. [6]
In August 2020, the company announced its Cascade family of system on a chip (SoC), its first clock chip product. [9] In October, the company introduced ApexMEMS resonators, designed for high volume, space constrained applications. [10]
In January 2021, based on SiTime's 2020 stock gain, Investors Business Daily included the company on its list of the 100 best stocks of 2020. [11]
In January 2022, CEO Vashist credited its relationship with its foundry partners and the small size of its chips for helping it avoid the chip shortages faced by other chip companies at the time, due to 2021–22 supply chain issues. [12] In February, the company introduced its XCalibur line of active resonators. [13]
In July 2023, SiTime released the SiT5543, part of its Endura family of MEMS ruggedized Super-TCXOs and in September the Epoch Platform MEMS OCXOs, the holdover oscillator to deliver this accuracy in real world environments. [14]
Products
SiTime manufacturers silicon-based MEMS timing devices, used as an alternative to quartz timers in precision timing applications such as controlling the timing of electronic systems, managing electronic transfer of data, setting radio frequencies or measuring time. [15] It provides MEMS resonators, oscillators and clocks. [9]
The company's XCalibur line of MEMs-based active resonators are designed to replace quartz resonators. [13]
The company's Elite Platform of Super-TCXOs (temperature compensated crystal oscillators) includes the Elite and Elite X. [7] [16] The devices are designed for harsh environments, such as with extreme temperatures, thermal shock and vibration. [16]
The company's Cascade family is a MEMS clock system-on-chip (SoC), with an integrated MEMS resonator, oscillator and clock integrated circuit (IC). [9]
The company also develops MEMs oscillators by integrating MEMS resonators with oscillator circuits and a phase-locked loop. [17]
The company's Emerald platform is an oven-controlled crystal oscillator (OCXO), which includes an on-chip heater, for extreme temperature environments. [18] The platform is designed for 5G networks and edge computing, where the equipment sits closer to customers, and must maintain precise timing in the face of environmental stressors such as airflow, temperature perturbation, vibration, shock, and electromagnetic interference (EMI). [8]
In July 2023, SiTime released the SiT5543, part of its Endura family of MEMS ruggedized Super-TCXOs and in September the Epoch Platform that delivers a stable clock to datacenter and network infrastructure equipment. [19]

Fabless manufacturing is the design and sale of hardware devices and semiconductor chips while outsourcing their fabrication to a specialized manufacturer called a semiconductor foundry. These foundries are typically, but not exclusively, located in the United States, China, and Taiwan. Fabless companies can benefit from lower capital costs while concentrating their research and development resources on the end market. Some fabless companies and pure play foundries may offer integrated-circuit design services to third parties.

Microelectromechanical system oscillators are devices that generate highly stable reference frequencies used to sequence electronic systems, manage data transfer, define radio frequencies, and measure elapsed time. The core technologies used in MEMS oscillators have been in development since the mid-1960s, but have only been sufficiently advanced for commercial applications since 2006. MEMS oscillators incorporate MEMS resonators, which are microelectromechanical structures that define stable frequencies. MEMS clock generators are MEMS timing devices with multiple outputs for systems that need more than a single reference frequency. MEMS oscillators are a valid alternative to older, more established quartz crystal oscillators, offering better resilience against vibration and mechanical shock, and reliability with respect to temperature variation.
