Product details

The DSC1121CM1-032.0000 is a 32 MHz MEMS-based XO (Standard) from Microchip's DSC1121 series, delivering CMOS output across a 2.25V to 3.6V supply range. Frequency stability is rated at ±50 ppm, which holds across the entire voltage and temperature envelope — no derating curve to chase.

MEMS vs quartz: the shock and temperature argument

The DSC1121CM1-032.0000 uses a MEMS resonator that withstands 50,000 g shock and 70 g vibration per the DSC1121 family datasheet (R*), which means it keeps the 32 MHz clock locked during a missile launch or a downhole hammer drill cycle.

Frequently asked questions

How can I order the DSC1121CM1-032.0000 or request a quote?

Submit an RFQ with your target quantity and delivery window. The DSC1121CM1-032.0000 is Active and sourced through independent distribution — price and lead time are confirmed per RFQ, not published as stock figures.

Can the DSC1121CM1-032.0000 replace a 32 MHz quartz oscillator?

Yes, if the board footprint matches the 6-SMD no-lead package (3.20mm x 2.50mm, 0.90mm seated height) and the system can accept the 2.25V to 3.6V supply range. The enable/disable function is a bonus — many quartz oscillators lack a disable pin. The MEMS construction also gives better vibration immunity than quartz, which matters in avionics and downhole tools.

Does the DSC1121CM1-032.0000 have an enable/disable function?

Yes. The enable/disable pin lets you gate the CMOS output while the MEMS resonator stays powered. In the disabled state, supply current drops to 22 mA max from the 35 mA max active draw — useful for power-cycled or battery-backed systems.
