Product details

100 MHz MEMS clock — industrial temperature range

The DSC1033DI1-100.0000T is a 100 MHz MEMS-based XO (Standard) from Microchip's PureSilicon™ series, delivering a CMOS output at 3.3 V with ±50 ppm frequency stability. The MEMS resonator eliminates quartz startup issues and withstands vibration better than a crystal — relevant for factory-floor or outdoor telecom gear where the board sees shock and wide thermal swings.

Standby function saves battery power

Normal operation draws 5 mA typ, so the standby mode extends sleep life by orders of magnitude.

Microchip lists the DSC1033DI1-100.0000T as Obsolete.

Frequently asked questions

What is the replacement for DSC1033DI1-100.0000T?

Microchip has not published an official direct replacement for the DSC1033DI1-100.0000T. A functionally equivalent MEMS oscillator with the same 100 MHz, 3.3 V, CMOS output, and ±50 ppm stability in a 4-SMD no-lead package would require a board-level cross-check — contact us with your BOM for a pin-compatible recommendation.

How can I order the DSC1033DI1-100.0000T or check availability?

Submit an RFQ through this page; we confirm availability and current pricing from independent surplus sources at quote time. No stock-holding claim — each lot is verified before commitment.

Does the DSC1033DI1-100.0000T have a standby function?

Yes, the DSC1033DI1-100.0000T includes a Standby (Power Down) function. When enabled, the supply current drops to 1 µA max, making it suitable for battery-powered or duty-cycled applications.

What is the frequency stability of the DSC1033DI1-100.0000T?

This is a standard stability grade for general-purpose clocking — confirm it meets your system's jitter budget before committing.

What is the output type of the DSC1033DI1-100.0000T?

The DSC1033DI1-100.0000T provides a CMOS output, which is a single-ended, rail-to-rail logic level compatible with most digital ICs at 3.3 V.
