Product details

MEMS oscillator replaces quartz with wider temperature range

The DSC1121CM1-030.0000 is a 30 MHz MEMS-based oscillator from Microchip's DSC1121 series, delivering a CMOS output from a 2.25V to 3.6V supply rail.

Enable/Disable pin and supply flexibility

The 22 mA maximum supply current at 30 MHz is low enough to run from a 3.3V or 2.5V rail without a dedicated regulator; the 2.25-3.6V range covers both standard logic supplies.

The 6-SMD no-lead package (3.20mm x 2.50mm, 0.90mm seated height) is a standard footprint shared across the DSC1121 family, so a single PCB layout can accommodate frequency variants without a board spin.

Frequently asked questions

Where can I buy DSC1121CM1-030.0000 and how is it quoted?

Submit an RFQ for a firm quote and lead time.

Is DSC1121CM1-030.0000 a direct replacement for a standard quartz oscillator?

Yes — the MEMS resonator is pin-compatible with most 6-pin SMD quartz oscillators in the same footprint. The CMOS output and enable/disable function match the standard XO interface, so no board changes are needed. The MEMS part offers better shock resistance and wider temperature range than quartz.

What is the frequency stability of DSC1121CM1-030.0000?

±50 ppm over the full -55°C to 125°C range. This includes initial tolerance, temperature drift, and aging — the MEMS resonator's low aging rate means the stability holds over the product lifetime without recalibration.
