Product details

MEMS oscillator for low-power 25 MHz clocking

The DSC1018DI1-025.0000 is a MEMS-based XO (Standard) from Microchip's DSC1018 series, delivering a fixed 25 MHz CMOS output from a 1.8V supply rail. The 3 mA typical supply current (1 µA in standby) suits battery-powered and duty-cycled systems where every microamp matters.

Standby power-down for sleep-mode savings

For a wireless sensor node that sleeps 99% of the time, this reduces the average clock-power draw from 3 mA to near-zero, directly extending battery life between charges.

Frequently asked questions

What is the standby power-down function on DSC1018DI1-025.0000?

The Standby (Power Down) function disables the oscillator output and reduces supply current to 1 µA typical. Pull the enable pin low to enter standby; pulling it high resumes normal 25 MHz output. This is useful for battery-powered devices that duty-cycle their main clock.

Can DSC1018DI1-025.0000 operate at 3.3V?

No — this variant is specified for a 1.8V supply only. For a 3.3V rail, look at the DSC1018 series parts with a 3.3V option in the ordering code. The 1.8V output swing will not meet CMOS VIH thresholds on a 3.3V logic input without a level translator.
