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 have a typical stability of ±100ppm at -40°C to 125°C. These MultiVolt oscillators will function from a fixed or battery level voltage from 1.8V to 3.3V and they are ideal for low-power battery applications wherever a stable 32.768kHz is needed.
