Product details

The DSC1121CE5-108.0000 is a MEMS-based standard oscillator delivering a 108 MHz CMOS output from a 2.25V to 3.6V supply rail. The MEMS resonator eliminates quartz crystal aging and improves shock/vibration tolerance — relevant for engine-bay and chassis-domain electronics where a quartz can drift or fracture under mechanical stress. The ±10 ppm frequency stability holds the timing budget across that temperature span without external compensation.

The 2.25V–3.6V supply range covers 2.5V and 3.3V logic rails without a dedicated LDO. CMOS output swings rail-to-rail into standard digital loads. The 6-SMD no-lead package (3.20 mm × 2.50 mm footprint, 0.90 mm seated height) fits tight PCB layouts; the no-lead land pattern requires a solder-paste stencil with aperture matching the pad dimensions on the datasheet footprint drawing.

Frequently asked questions

Is DSC1121CE5-108.0000 a MEMS oscillator?

Yes. The base resonator is MEMS, not quartz. This means no crystal aging drift and higher resistance to shock and vibration — a practical advantage for automotive and industrial environments where quartz oscillators can fail mechanically.

Is DSC1121CE5-108.0000 AEC-Q100 qualified?

Yes, the ratings field carries AEC-Q100 qualification. This qualifies the part for automotive applications under the standard's temperature grade and reliability stress requirements.

Can DSC1121CE5-108.0000 replace a quartz oscillator?

Functionally yes — it provides the same clock signal. The MEMS construction offers better long-term frequency stability (no crystal aging) and higher shock/vibration tolerance, but the pinout and footprint must match the existing quartz oscillator's 6-SMD no-lead layout to be a drop-in replacement.
