Product details

The DSC1001AI1-025.0000 is a 25 MHz MEMS-based XO (Standard) from Microchip's DSC1001 series, delivering a CMOS output over a 1.8V to 3.3V supply range.

Supply voltage and output compatibility

Operating from 1.8V to 3.3V, this oscillator can be powered from a 1.8V core rail, a 2.5V I/O rail, or a 3.3V peripheral rail without an external LDO — the wide range simplifies BOM consolidation across mixed-voltage designs. The CMOS output drives standard logic inputs directly; no termination or level translation is needed when feeding an MCU clock input or a PLD global clock buffer.

Frequently asked questions

Can DSC1001AI1-025.0000 replace a standard quartz oscillator?

Yes — the MEMS resonator is pin-compatible with many 4-pad quartz oscillators in the same 7.00 mm x 5.00 mm footprint. The CMOS output and 1.8V–3.3V supply range match common quartz XO specifications. The MEMS version offers better shock and vibration immunity and eliminates quartz startup time.

Does DSC1001AI1-025.0000 have a standby or power-down function?

Yes, the function is listed as Standby (Power Down). When the enable pin is driven low, the oscillator stops and the supply current drops to near-zero, allowing the device to be gated for power-saving sleep modes.
