SiTime Corporation recently launched its innovative SymphonicTM mobile clock generator, the SiT30100.
This groundbreaking device features an integrated MEMS resonator, delivering highly accurate and resilient clock signals tailored for 5G, GNSS, and IoT applications such as smartphones, tablets, laptops, and asset trackers. Designed to withstand extreme environmental conditions, the Symphonic clock generator not only enhances system reliability but also plays a pivotal role in enabling next-generation connectivity, unlocking a projected served addressable market (SAM) of $2 billion over the next five years.
Key features of the SiT30100 include four outputs capable of 76.8 MHz, 38.4 MHz, or 19.2MHz, suitable for baseband, RF, and GNSS applications. Its integrated MEMS resonator provides a smaller, single-chip solution that measures only 2.22 mm², streamlining design and reducing system complexity. The device incorporates a high-precision temperature-to-digital converter (TDC) with a UART interface, enabling real-time temperature compensation and achieving frequency stability as low as ±0.5 ppm. It demonstrates superior dynamic stability under airflow and thermal shock conditions, crucial for maintaining performance in mobile environments. Multiple Output Enable pins allow system power optimization and EMI reduction by selectively powering clock outputs. Operating across a temperature range of -30°C to +90°C (with options for wider ranges upon request), the SiT30100 is engineered for demanding applications requiring robust, precise timing.
