Product details

The DSC1101DI5-020.0000T is a 20 MHz MEMS-based oscillator (XO) with a CMOS output, built to serve as the master clock on a digital PCB without the startup or aging quirks of a quartz crystal.

The supply voltage range of 2.25V to 3.6V lets this oscillator run directly from a 2.5V or 3.3V rail — no extra LDO just for the clock.

Housed in a 6-VDFN package measuring 2.50 mm x 2.00 mm with a seated height of 0.90 mm, this is a low-profile, small-footprint part that fits on dense mixed-signal boards where board area is tight.

Frequently asked questions

What supply voltage does the DSC1101DI5-020.0000T need?

It accepts 2.25V to 3.6V, covering common 2.5V and 3.3V logic rails. The wide range means you can power it from the same rail as the downstream logic without a dedicated regulator.

What does the standby (power-down) function do on this oscillator?

When the standby pin is asserted, the oscillator stops and draws 95 µA max instead of the 35 mA active current. This lets a microcontroller or system controller gate the clock during sleep modes to save power.
