Product details

12 MHz MEMS oscillator for tight-timing BOMs

Supply voltage tolerance and power budget

The supply voltage range spans 2.25V to 3.6V, covering both 2.5V and 3.3V logic rails without an external regulator. The 22 mA standby draw is higher than a typical quartz oscillator's disable current, so factor that into a battery-powered sleep budget.

Housed in a 6-VDFN exposed pad package measuring 7.00 mm x 5.00 mm with a seated height of 0.90 mm.

The DSC1121 series is an established MEMS oscillator family, so long-term availability is stable.
