Product details

20 MHz MEMS oscillator for timing replacement

The DSC1033DI1-020.0000 is a fixed-frequency 20 MHz XO (Standard) oscillator built on a MEMS resonator rather than a quartz crystal, outputting CMOS levels at 3.3V supply rail.

Active supply current is 3mA typ at 20 MHz — the MEMS core draws less than a comparable quartz oscillator at the same frequency, which matters for battery-powered or thermally constrained boards.

No direct factory support or warranty applies; buyer assumes date-code and condition risk.

Frequently asked questions

How can I order the DSC1033DI1-020.0000 or check availability?

Submit an RFQ through this page. No stock-holding claim is made here.

Can I substitute DSC1033DI1-020.0000 with a standard crystal oscillator?

Not directly — a quartz crystal oscillator typically requires external load capacitors and has different start-up characteristics. The DSC1033DI1 is a MEMS-based XO with an integrated resonator and CMOS output; a quartz XO with the same footprint, frequency, and supply voltage may work, but verify the standby (power-down) function and frequency stability (±50ppm) are compatible.
