SIT1552AI-JE-DCC-32.768E offers initial accuracy at 25°C ±5ppm, frequency stability over temperature range -40 to 85°C ±5ppm and frequency stability vs power supply voltage in range 1.5 to 3,6V ±1.5ppm.
Thus, the largest frequency deviation is ±11.5ppm.
For comparison, tuning-fork quartz crystal offers initial accuracy at 25°C ±20ppm and parabolic temperature coefficient -0.04e-6/°C2, which results in a frequency deviation -169ppm at -40°C and -144ppm at 85°C.
