Product details

40 MHz MEMS clock — obsolete, sourced per BOM

The DSC1030BC1-040.0000T is a 40 MHz MEMS-based XO (Standard) oscillator from Microchip's PureSilicon™ series, delivering a CMOS output at 3V supply with ±50ppm frequency stability.

Where this oscillator fits — and where it does not

The 4-SMD, No Lead package (5.00mm x 3.20mm footprint, 0.90mm seated height) is a standard MEMS oscillator land pattern, compatible with common reflow profiles.

Power-down standby for battery-sensitive designs

Frequently asked questions

Can I use DSC1030BC1-040.0000T with a 3.3V supply?

No — the specified supply voltage is 3V. Operating at 3.3V exceeds the rated voltage and may cause frequency drift, increased jitter, or damage. The part is not guaranteed to function outside its 3V rail.

How do I get current pricing and availability for DSC1030BC1-040.0000T?
