Product details

MEMS oscillator for timing applications

The DSC1033CI1-014.7456T is a MEMS-based XO (Standard) oscillator from Microchip's PureSilicon™ series, delivering a 14.7456 MHz CMOS output with ±50 ppm frequency stability. Its 3.3V supply and 3 mA typical current draw suit power-conscious designs in industrial control, telecom, and embedded systems where a quartz-free resonator reduces board-level vibration sensitivity.

Microchip lists the DSC1033CI1-014.7456T as obsolete. Date-code provenance should be verified before committing to a production run.

Frequently asked questions

What is the replacement for DSC1033CI1-014.7456T?

Microchip has not published a direct replacement for this obsolete MEMS oscillator. For a new design, consider a current-generation MEMS XO in the same 3.2 mm × 2.5 mm footprint, such as Microchip's DSC1000 series, but verify pinout and electrical compatibility against the original datasheet before substituting.
