Ultra-small, precision 32 kHz TCXO

Manufacturer's part number :


Manufacturer SiTime


Description :

SiTime's TempFlat MEMS technology enables the first 32 kHz TCXO in a 1.2mm² chip-scale package, the world's smallest footprint. Typicalcore supply current is only 1µA. 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 + over temperature).
