Product details

The DSC1001CI1-027.0000 is a standard XO (Standard) oscillator built on a MEMS resonator, not a quartz crystal — the MEMS die is hermetically sealed in a 4-SMD, No Lead package measuring 3.20mm x 2.50mm. It delivers a fixed 27 MHz CMOS output, covering the common frequency for USB, Ethernet, and MCU clock domains.

Automotive-grade qualification and supply flexibility

Its supply voltage range of 1.8V to 3.3V covers the three most common logic rails in automotive and industrial systems, so it can be driven directly from a 1.8V core rail or a 3.3V I/O rail without an intermediate regulator.

Standby power-down for battery-conscious designs

Frequently asked questions

What is the exact frequency of DSC1001CI1-027.0000?

The exact output frequency is 27 MHz, with a frequency stability of ±50 ppm.

Is DSC1001CI1-027.0000 AEC-Q100 qualified?

Yes, it carries AEC-Q100 ratings, making it suitable for automotive applications that require PPAP and reliability qualification.

What is the difference between DSC1001CI1 and a crystal oscillator?

The DSC1001CI1 uses a MEMS resonator instead of a quartz crystal. This means it is less sensitive to vibration and shock, and it integrates the oscillator circuit in a single package — no external load capacitors are needed. The output is a full-swing CMOS signal, not a sine wave from a bare crystal.
