SiTime SIT1576AI-J1-33E-0200.000000

The SiT1576 is an ultra-small, ultra-low-power, factory-programmable TCXO with an output frequency range of 1 Hz to 2.5 MHz. SiTime's silicon MEMS technology enables this 1 Hz – 2.5 MHz TCXO to achieve the world's smallest footprint in a chip-scale package (CSP). Typical supply current is only 6 μA (at 100 kHz). SiTime's MEMS oscillator consists of a MEMS resonator and a programmable analog circuit. The SiT1576 MEMS resonator is fabricated using SiTime's proprietary MEMS First® process. The key manufacturing step is EpiSeal®, during which the MEMS resonator is annealed at temperatures exceeding 1000°C. EpiSeal creates an extremely robust, clean vacuum cavity that encapsulates the MEMS resonator, ensuring optimal performance and reliability. During the EpiSeal process, a polysilicon cap is grown on top of the resonator cavity, eliminating the need for an additional cap wafer or other special packaging. As a result, SiTime's MEMS resonator die can be handled like any other semiconductor die. A unique outcome of SiTime's MEMS First and EpiSeal manufacturing processes is the ability to integrate SiTime's MEMS die with a SoC, ASIC, microprocessor, or analog chip in a single package, eliminating external timing components and delivering a highly integrated, smaller, and more cost-effective solution for customers.
