32kHz oscillator for auto

Author: EIS Release Date: Oct 26, 2022

SiTime has introduced a  32 kHz oscillator family that provides accurate time keeping for ADAS,  infotainment, instrument clusters and ECUs.

 

To conserve power, electronic subsystems need to be turned on and off frequently and accurately. Since the 32 kHz oscillator (XO) is the time keeping element, and is always-on, its accuracy and power consumption play a significant role in reducing overall system power.

 

The SiT1881 is the industry’s smallest XO, delivering ±50 ppm of stability, the most accurate amongst all 32 kHz XOs, with up to 20% lower power.

 

As electronics become smaller and denser, semiconductor devices also need to shrink. Unlike legacy quartz alternatives, in which resonator size increases with decreasing frequency, SiTime MEMS technology enables SiT1881 XO to fit in a tiny QFN package that is 30% smaller.

 

Stability: ±50 ppm frequency stability over entire temperature range ensures robust system performance in hostile environments and lower power consumption

Ultra-low power: 490 nA current (<0.6 µW typical power consumption)

Industry’s smallest form-factor: 1.2 mm x 1.1 mm x 0.55 mm QFN package (1.32 mm2footprint, 0.67 mm3 volume)

AEC-Q100 Grade 2 qualified with extended -40 oC to +105 oC temperature range

Superior reliability: 2 billion hours MTBF

Industry’s smallest, ultra-low power 32.768 kHz automotive XO designed to operate over a wide voltage and temperature range

Engineering samples of the SiT1881 oscillators will be available through SiTimeDirect beginning Nov. 1, 2022. Volume production is expected in Q2 2023
