This device is a 32.768 kHz MEMS super-TCXO optimized for battery-powered timing applications. The SIT1566AI-JE-30E-32.768 variant provides ±5 ppm all-inclusive frequency stability, a 3.0 V nominal supply option, and an industrial operating range from -40°C to +85°C. Typical supply current is 4.5 µA with no load, and integrated phase jitter is 2.5 nsRMS over 100 Hz to 16.384 kHz. It uses an LVCMOS output and is housed in a 1.5 x 0.8 mm chip-scale package without requiring an external bypass capacitor under normal operating conditions.
