This 32.768 kHz MEMS temperature-compensated oscillator is specified for ±5 ppm frequency stability over a 0°C to 70°C operating range in a 1.5 x 0.8 mm chip-scale package. It operates from a 1.5 V to 3.63 V supply, and the SiT1552 family specifies 0.99 µA typical core current at 1.8 V with 180 ms typical start-up time. This orderable variant is listed with default output drive strength, 350 mV DC-coupled low-level or AC swing, and an AC-coupled receiver high-level option. The family is also specified for 2.5 µs peak-to-peak long-term jitter, 35 ns RMS period jitter, and ±1 ppm first-year aging.
