SiTime’s Chorus redefines how precision time is generated, delivered, and sustained in data-centric systems. Unlike traditional quartz-based clock designs that require multiple discrete components and suffer from environmental instability, Chorus is the world’s first fully integrated MEMS-based clock-system-on-a-chip (ClkSoC). It combines a MEMS resonator, oscillator, and clock IC into a single device—delivering ultra-precise, programmable timing from 1 MHz to 700 MHz, with sub-100 femtosecond jitter and robust environmental immunity in a compact 4mm x 4mm package.
Purpose-built for AI infrastructure, Chorus provides the synchronization backbone required to align tens of thousands of high-performance processors. According to IEEE, poor synchronization leads to GPU idle times of up to 57%. Chorus solves this by enabling tightly coordinated sleep/wake cycles and minimizing latency across compute clusters.
This breakthrough architecture eliminates quartz-related design pain points such as crystal matching, board tuning, and EMI sensitivity. Its digital configurability dramatically simplifies integration while reducing design cycles by up to six weeks.
Compared to legacy quartz solutions, Chorus is:
• 4X more stable
• 4X more power-efficient
• 30X more reliable
• 50% smaller
Chorus is not just replacing quartz—it’s ushering in a new era of software-defined timing that meets the scale, speed, and complexity of AI, 5G, and automotive systems.
Now shipping to leading innovators like Tesla, Apple, NVIDIA, and top-tier hyperscalers, Chorus is enabling the most demanding applications in datacenter, aerospace, industrial, and edge environments.
