SIT1552

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 ±5 ppm to ±20 ppm (initial and over temperature).
