【文字介绍】

SiT1566 is an ultra-small, micropower 32.768 kHz TCXO optimized for battery-powered applications. SiTime’s silicon MEMS technology enables the first 32 kHz TCXO in the world’s smallest footprint and chip-scale packaging (CSP). Typical supply current is 4.5 μA under no load condition.
SiTime's MEMS oscillator consists of a MEMS resonator and a programmable analog circuit. SiT1566 MEMS resonator is built with SiTime’s unique MEMS First™ process. A key manufacturing step is EpiSeal™ during which the MEMS resonator is annealed with temperatures over 1000°C. EpiSeal creates an extremely strong, clean, vacuum chamber that encapsulates the MEMS resonator and ensures the best performance and reliability. During EpiSeal, a poly silicon cap is grown on top of the resonator cavity, which eliminates the need for additional cap wafers or other exotic packaging. As a result, SiTime’s MEMS resonator die can be used like any other semiconductor die. One unique result of SiTime’s MEMS First and EpiSeal manufacturing processes is the capability to integrate SiTime’s MEMS die with a SOC, ASIC, microprocessor or analog die within a package to eliminate external timing components and provide a highly integrated, smaller, cheaper solution to the customer.
