Product details

MEMS oscillator replaces quartz — supply chain angle

The DSC1121BE5-024.0000T is a 24 MHz MEMS-based XO from Microchip's DSC1121 series, delivering ±10 ppm frequency stability without a quartz crystal.

Supply voltage and output — BOM-fit checklist

Runs on any rail from 2.25 V to 3.6 V — the same BOM position works across 2.5 V and 3.3 V logic domains without a separate regulator.

Temperature grade and package — board integration

The 6-SMD no-lead package measures 5.00 mm x 3.20 mm with a seated height of 0.90 mm — a standard footprint that matches many quartz oscillator pads, so a board originally laid out for a quartz XO can often take this MEMS part without a layout change.

Frequently asked questions

Can DSC1121BE5-024.0000T replace a standard quartz crystal oscillator?

Yes, in most cases. The DSC1121BE5-024.0000T is a MEMS-based XO with CMOS output and a 6-SMD no-lead package that matches the footprint of many quartz oscillators. The ±10 ppm stability covers typical clock requirements for MCUs, FPGAs, and Ethernet PHYs.

What is the difference between DSC1121 and DSC1122?

The DSC1121 and DSC1122 are both MEMS XO families from Microchip. The DSC1121 series offers standard frequency stability options including ±10 ppm, while the DSC1122 series typically provides tighter stability grades. Pin-compatible in the same 6-SMD package, so a BOM swap between the two requires only a stability spec review.
