The MultiVolt™ series oscillators are performance-based system clocks. Operating at 32.768kHz, the MultiVolt series can capture any day, date, or time interval. The ECS-327MV and ECS-327MVATX have a typical stability of ±20ppm at -40°C to +85°C. The ECS-327ATQMV is AEC-Q200 qualified and has a typical stability of ±100ppm at -40°C to +125°C. Also, these MultiVolt Oscillators will function from a fixed or battery level voltage from 1.6V to 3.6V. They are ideal for low power battery applications wherever a stable 32.768kHz clock is needed.
