Product details

MEMS oscillator replacing quartz at 27 MHz

The MEMS base resonator eliminates quartz cold-start jitter and vibration sensitivity, making it a drop-in replacement for a standard 27 MHz quartz oscillator in the same 4-VFLGA footprint.

Automotive-grade qualification and supply flexibility

The qualification covers the reliability stress and PPAP requirements for production vehicle programs.

Wide supply range and low power footprint

The supply voltage spans 1.8V to 3.3V, covering 1.8V-core MCUs and 3.3V peripheral buses on the same BOM line without a level translator. Typical supply current is 1.3 mA max, which keeps the thermal budget low in the 1.6 mm x 1.2 mm 4-VFLGA package.

Frequently asked questions

Can the DSC6003HI2B-027.0000 replace a standard 27 MHz quartz oscillator?

The MEMS base resonator provides equivalent frequency stability (±25 ppm) and CMOS output, with improved vibration and shock resistance compared to quartz. No board layout change is needed if the original part was also a 4-VFLGA XO.

Is the DSC6003HI2B-027.0000 compatible with 3.3V logic?

Yes, the supply voltage range is 1.8V to 3.3V, and the output is CMOS. It drives 3.3V logic inputs directly without a level translator. The same part also works with 1.8V and 2.5V rails, simplifying multi-voltage BOMs.
