Ultra-Small, Low-Power, Low-Jitter, ±5 ppm, 32.768 kHz TCXO


SiTime's TempFlat MEMS technology, coupled with our mixed-signal capability, enables the smallest 32-kHz TCXO in a 1.2mm² chip-scale package. These devices use MEMS resonators that are manufactured using the latest generation of EpiSeal™ technology which hermetically seals the resonator, making it impervious to all small-molecule gases. Additionally, the SiT1580 has a high shock and vibration survivability. These TCXOs are factory calibrated over multiple temperature points to guarantee extremely tight ±5 ppm all-inclusive frequency stability. Typical core supply current is only 4.5 μA.
