What SiTime does

SiTime Corporation (Nasdaq: SITM) is an analog semiconductor company founded in 2005 and headquartered in Santa Clara, California, that designs and sells MEMS-based silicon precision timing devices replacing legacy quartz crystal oscillators. The company serves OEM customers across communications and enterprise (including AI data centers, 5G ORAN, high-speed networking), automotive (AEC-Q100 qualified), aerospace and defense, industrial, mobile and IoT, medical, and consumer electronics segments.

SiTime's technology platform combines proprietary MEMS resonators with programmable analog circuitry, temperature compensation, and the TimeFabric software suite to deliver precision timing in the sub-ppb to ppm stability range. Key product families include Titan Platform MEMS resonators (4-7x smaller than the smallest quartz crystals), Elite 2 Super-TCXO for AI data center GPU cluster synchronization, Endura Super-TCXO for GNSS-denied environments, Epoch Platform MEMS OCXOs with up to 12-hour holdover, and the ClkSoC portfolio (SiT95145 Cascade clock system-on-chip and Chorus Clock Generator). The pending acquisition of Renesas' timing business expands the clocking portfolio by more than 10x and adds clock generators, buffers, network synchronizers, and jitter attenuators.

SiTime generates revenue primarily through unit sales of MEMS timing components via direct enterprise field sales, authorized channel partners, and the SiTimeDirect self-serve e-commerce platform offering over 150 billion programmable configurations. The TimeFabric software suite is bundled with hardware. Long-term financial targets are 60-65% gross margins and 25-30% annual revenue growth. Q1 2026 revenue was $113.6M (up 88% YoY) with non-GAAP gross margin of 64.5% and $38.9M net income, with CED segment revenue up 158% YoY to two-thirds of total sales.

Core offering

SiTime designs, manufactures, and sells MEMS-based silicon precision timing semiconductors that replace legacy quartz crystal oscillators and resonators. Its portfolio spans MEMS oscillators (MHz, 32 kHz, µPower), Super-TCXOs, MEMS OCXOs, clock generators, clock buffers, jitter cleaners, network synchronizers, MEMS resonators, and the TimeFabric software suite for IEEE 1588 PTP and holdover management, sold to OEM customers across AI data centers, 5G ORAN, automotive, aerospace & defense, industrial, mobile/IoT, and medical markets.

Product overview

SiTime offers a platform-plus-modules precision timing portfolio built on its Titan Platform MEMS Resonators, from which the company derives a broad set of MEMS oscillator families (including MHz Oscillators such as differential, LVCMOS, spread-spectrum, VCXO, and DCXO variants; 32 kHz & µPower Oscillators; Ultrastable MHz Super-TCXOs such as Elite 2 Super-TCXO, Endura Super-TCXO, and SiT5977; Programmable OCXOs including the Epoch Platform; Clock Generators including Symphony Mobile; Clock Buffers; and Jitter Cleaners/Network Synchronizers including SiT95145 Cascade Clock System). The TimeFabric Software Suite complements the silicon portfolio as a configuration and design-in tool. The portfolio spans ruggedized timing for harsh environments, AEC-Q100 qualified automotive timing (Endura), and infrastructure-grade synchronization, with Renesas' timing business acquired in February 2026 extending the offering.
