This 32.768 kHz MEMS super-TCXO provides ±3 ppm total frequency stability across the industrial -40°C to +85°C range in a 1.5 x 0.8 mm chip-scale package. It operates from a 1.62 V to 3.63 V supply and draws 4.5 µA typical with no load. The LVCMOS output delivers 45% to 55% duty cycle with 2.5 ns RMS integrated phase jitter and 300 ms typical start-up time. It is intended for battery-powered timekeeping applications such as wearables, meters, and BLE-enabled IoT devices.
