Product details

The MEMS resonator is silicon-manufactured, which gives tighter frequency stability over temperature and eliminates the quartz start-up reliability issue in humid or vibration-prone environments. The 27 MHz frequency is common for USB, Ethernet PHY reference clocks, and MCU main oscillators.

Industrial temperature grade and standby power

Use it in outdoor telecom enclosures, factory-floor controllers, engine-bay electronics, or any environment where a commercial-grade (0-70°C) oscillator would drift or fail. For a battery-powered sensor node that sleeps most of the time, this keeps the oscillator's own draw negligible against the battery self-discharge. Active current is 10 mA max at 27 MHz.

4-SMD, No Lead package measuring 3.20 mm x 2.50 mm with a seated height of 0.90 mm max.

Frequently asked questions

Can DSC1033CI2-027.0000T directly replace a traditional quartz crystal oscillator?

Yes, if the existing quartz XO is a 3.3 V, CMOS output, 27 MHz device in a 3.2 x 2.5 mm 4-pin no-lead package. The MEMS resonator eliminates quartz start-up issues and offers tighter frequency stability (±25 ppm,) over the industrial temperature range. Confirm the footprint matches your PCB land pattern — the 4-SMD pad layout is industry-standard for this size.
