Product details

25 MHz MEMS clock for low-power digital logic

The DSC1033AC1-025.0000T is a 25 MHz MEMS-based oscillator (XO) with a CMOS output, operating from a 3.3 V supply rail. Active current is 3 mA typical, dropping to 1 µA maximum in standby (power-down) mode via the enable/disable function. This makes the part suited for battery-operated equipment where the clock tree must be gated during system sleep.

Standby function and system-level power gating

The standby (power-down) pin disables the output and internal bias circuits, reducing supply current to 1 µA maximum.

Frequently asked questions

What is the frequency and output type of the DSC1033AC1-025.0000T?

The oscillator outputs a 25 MHz CMOS signal. The CMOS logic level is compatible with 3.3 V digital inputs without external level translation.

What is the standby power consumption of the DSC1033AC1-025.0000T?

In standby (power-down) mode, the maximum supply current is 1 µA. This allows the clock to be disabled during system sleep without draining the battery.
