SiTime Corporation is a publicly traded fabless chipmaker based in Santa Clara, California that develops micro-electromechanical systems (MEMS), used for timing devices in electronics.
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]
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]
SiTime products and services focus on three main market segments—automotive, [20] aerospace and defense [21] and enterprise. [22]
SiTime is headquartered in Santa Clara, California. In its 2021 annual report, the company reported 279 full time employees in the United States, France, Malaysia, the Netherlands, Taiwan, Japan and Ukraine. It also reported its top customers as Apple, Fitbit, Garmin, Samsung, Google, Microsoft, Dell, HiKVision and Huami. [23]
The company has three customer segments: The Mobile, IoT and Consumer segment develops high-volume, lower-cost devices for products like smartphones and fitness trackers. The Communications and Enterprise segment develops products for networking, telecom and data center products. Its Industrial, Automotive and Aerospace segment includes chips for electric vehicles, satellites and missiles. [24]
German industrial company Robert Bosch and Taiwanese semiconductor company TSMC are the company's foundry partners. [8]

CSR was listed on the London Stock Exchange and was a constituent of the FTSE 250 Index until it was acquired by Qualcomm in August 2015. Under Qualcomm's ownership, the company was renamed Qualcomm Technologies International, Ltd.
A crystal oven is a temperature-controlled chamber used to maintain the quartz crystal in electronic crystal oscillators at a constant temperature, in order to prevent changes in the frequency due to variations in ambient temperature. An oscillator of this type is known as an oven-controlled crystal oscillator. This type of oscillator achieves the highest frequency stability possible with a crystal. They are typically used to control the frequency of radio transmitters, cellular base stations, military communications equipment, and for precision frequency measurement.
Integrated circuit design, semiconductor design, chip design or IC design, is a sub-field of electronics engineering, encompassing the particular logic and circuit design techniques required to design integrated circuits, or ICs. ICs consist of miniaturized electronic components built into an electrical network on a monolithic semiconductor substrate by photolithography.
A thin-film bulk acoustic resonator is a device consisting of a piezoelectric material manufactured by thin film methods between two conductive – typically metallic – electrodes and acoustically isolated from the surrounding medium. The operation is based on the piezoelectricity of the piezolayer between the electrodes.
Microchip Technology Incorporated is a publicly listed American corporation that manufactures microcontroller, mixed-signal, analog, and Flash-IP integrated circuits. Its products include microcontrollers, Serial EEPROM devices, Serial SRAM devices, embedded security devices, radio frequency (RF) devices, thermal, power, and battery management analog devices, as well as linear, interface and wireless products.
A ceramic resonator is an electronic component consisting of a piece of a piezoelectric ceramic material with two or more metal electrodes attached. When connected in an electronic oscillator circuit, resonant mechanical vibrations in the device generate an oscillating signal of a specific frequency. Like the similar quartz crystal, they are used in oscillators for purposes such as generating the clock signal used to control timing in computers and other digital logic devices, or generating the carrier signal in analog radio transmitters and receivers.

Crystal oscillators can be manufactured for oscillation over a wide range of frequencies, from a few kilohertz up to several hundred megahertz. Many applications call for a crystal oscillator frequency conveniently related to some other desired frequency, so hundreds of standard crystal frequencies are made in large quantities and stocked by electronics distributors. Using frequency dividers, frequency multipliers and phase locked loop circuits, it is practical to derive a wide range of frequencies from one reference frequency.

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.
