Product details

Automotive-grade MEMS oscillator for timing-critical designs

The DSC1001CE2-022.5792T is a MEMS-based XO (Standard) from Microchip's DSC1001 series, delivering a 22.5792 MHz CMOS output with ±25 ppm frequency stability. The wide supply range of 1.8V–3.3V lets it drop into existing 2.5V or 3.3V clock trees without a separate LDO.

Normal operation draws 6.3 mA max, which is typical for a 22.5792 MHz CMOS oscillator at 3.3V.

Housed in a 4-SMD, No Lead package measuring 3.20mm x 2.50mm with a seated height of 0.90mm. The MEMS resonator eliminates quartz crystal aging and start-up reliability concerns — the oscillator starts within microseconds, not milliseconds.

Availability confirmed at RFQ.

Frequently asked questions

Can DSC1001CE2 replace a 22.5792 MHz quartz oscillator?

Yes, it is a drop-in replacement for a 22.5792 MHz quartz oscillator in the same 4-SMD footprint, provided the supply voltage is within 1.8V–3.3V and the output is CMOS. The MEMS resonator offers better shock and vibration tolerance than quartz, and the ±25 ppm stability matches or exceeds many quartz XOs. No external load capacitors are needed.
