Ultra-small 32.768 kHz temperature-compensated MEMS oscillator for battery-powered timing applications. It provides ±5 ppm all-inclusive frequency stability, 2.5 ns RMS integrated phase jitter, and 4.5 μA typical supply current with no external bypass capacitor required under normal conditions. The device operates from 1.62 V to 3.63 V and is offered in a 1.5 x 0.8 mm chip-scale package with LVCMOS output. Industrial-grade versions support operation from -40 °C to +85 °C and are specified as Pb-free, RoHS, and REACH compliant.
