SiT1552 Series Ultra-Small Precision 32 kHz TCXOs

By SiTime 60

SiT1552 Series Ultra-Small Precision 32 kHz TCXOs

SiTime's TempFlat™ MEMS technology enables the first 32 kHz TCXO in a 1.2 mm2 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 + over temperature).

NanoDrive™ Output to Optimize Swing and Lower Power Graph

Reducing voltage swing with NanoDrive can reduce total supply current up to 40%. See NanoDrive product training module at https://www.digikey.com/en/ptm/s/sitime/nanodrive/tutorial
