Product details

18.75 MHz MEMS clock source with standby

The DSC1101CI1-018.7500 is a MEMS-based XO (Standard) oscillator from Microchip's DSC1101 series, delivering a fixed 18.75 MHz CMOS output. The MEMS resonator eliminates the quartz crystal — faster startup and better shock/vibration tolerance compared to a traditional crystal oscillator, relevant for industrial and portable designs. Supply voltage spans 2.25V to 3.6V, covering 2.5V and 3.3V logic rails without an external regulator.

Standby function and power budget

The Standby (Power Down) function drops current consumption to 95 µA max when disabled, versus 35 mA max during active operation. This makes the oscillator a fit for battery-powered devices that spend most of their time in sleep and wake on a threshold event.

It is available for new designs and volume production. Quoted to order against the BOM quantity; availability confirmed at RFQ.

Frequently asked questions

Where can I buy DSC1101CI1-018.7500 and what is the lead time?

We source this active Microchip oscillator through independent distribution. No stock-holding claim — availability is lot-specific per request.

Does the DSC1101CI1-018.7500 have a standby (power down) function?

Yes, the Standby (Power Down) function drops the supply current to 95 µA max when the oscillator is disabled. This is useful for intermittently operating systems that need to preserve battery life between active periods.
