SiTime's TempFlat MEMS(TM) technology enables the first 32 kHz ±3 ppm Super-TCXO in a 1.2mm2 chip-scale package, the world's smallest footprint. Typical core supply current is only 4.5 μA. The SiT1566 is factory calibrated over multiple temperature points to guarantee extremely tight ±3 PPM all-inclusive frequency stability.
