Ultra-Small µPower, ±5 to ±20 ppm, 32.768 kHz TCXO
SiTime's TempFlat MEMS technology enables the first 32 kHz TCXO in a 1.2mm2 chip-scale package, the world's smallest footprint. Typical core supply current is only 1 μA. And unlike standard oscillators, the SiT1552 features NanoDrive™, a factory-programmable output that reduces voltage swing to minimize power. The SiT1552 is factory calibrated over multiple temperature points to guarantee extremely tight frequency stability from ±10 ppm to ±20 ppm (initial and over temperature).
Video Demo: The SiT1552 is placed in temperature chamber that increases temp. from < -40 to +85 °C at a fast ramp rate of 4 degrees per second.
