This 32.768 kHz MEMS TCXO provides ±5 ppm frequency stability over 0°C to 70°C in a 1.5 x 0.8 mm chip-scale package. It operates from a 1.5 V to 3.63 V supply and has 0.99 µA typical core current at 1.8 V with no load. The output is rail-to-rail LVCMOS with a 48% to 52% duty cycle, and start-up time is 180 ms typical. The device is optimized for compact, battery-powered timekeeping designs that need low power and tight temperature compensation.
