This 32.768 kHz MEMS super-TCXO provides ±3 ppm all-inclusive frequency stability in a 1.5 x 0.8 mm chip-scale package. It draws 4.5 µA typical supply current and operates from 1.62 V to 3.63 V, making it suitable for battery-powered RTC and wearable designs. The LVCMOS output offers 45% to 55% duty cycle with 2.5 ns RMS integrated phase jitter and 300 ms start-up time. It supports industrial operation from -40°C to +85°C and is specified as Pb-free, RoHS compliant, and REACH compliant.
