Product details

The DSC1033CI1-100.0000T is a 100 MHz XO (standard oscillator) from Microchip's PureSilicon™ MEMS family, outputting CMOS logic levels from a 3.3V supply rail. Its MEMS base resonator replaces a quartz crystal with a silicon die, giving it shock and vibration tolerance suited for industrial environments across -40°C to 85°C. The 4-SMD no-lead package measures 3.20 mm x 2.50 mm with a seated height of 0.90 mm, fitting standard oscillator footprints for 100 MHz clock generation.

Typical supply current is 5 mA, dropping to 1 µA in standby (power-down) mode — the standby function lets the oscillator be gated off by a logic signal to save power in battery-backed designs.

Frequently asked questions

Is the DSC1033CI1-100.0000T compatible with standard 100 MHz CMOS logic?

Yes — the CMOS output at 3.3V supply directly drives standard 3.3V CMOS logic inputs at 100 MHz without a level translator.

What replaces the DSC1033CI1-100.0000T?

Microchip has not published an official successor for this obsolete order code. A functionally equivalent MEMS oscillator in the same 4-SMD footprint with 100 MHz, CMOS output, 3.3V, and ±50 ppm stability would be the closest drop-in candidate — confirm pin compatibility and standby function before committing a new BOM line.
