MEMS Voltage-Controlled Oscillators

SiTime's voltage-controlled oscillators (VCXOs) are highly flexible, high-performance, voltage-controlled oscillators with LVCMOS-/LVTTL-compatible outputs, as well as LVPECL, LVDS, and HCSL. These devices support many frequencies, along with any combination of voltage, pull range, and package type. The superior pull range linearity and tuning slope consistency (Kv) is ten times better than quartz crystal VCXOs, thereby simplifying PLL and clock synchronization designs. Many of these parts are also footprint compatible with legacy quartz devices. SiTime has also introduced a few new devices that are based on the unique Elite Platform™, which deliver exceptional dynamic performance and are optimal for environmental hazards such as shock, vibration, power supply noise, EMI, and board bending.

SiTime’s MEMS oscillators exhibit performance far greater than comparable crystal oscillators. SiTime has in-house MEMS and analog CMOS expertise, which allows SiTime to develop very reliable products. Oscillators are available in plastic packages which are up to 54 times more immune to external electromagnetic fields than quartz oscillators. These MEMS oscillators are vacuum-sealed using an advanced EpiSeal® process that eliminates foreign particles, providing long-term aging and reliability.
