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.","metaTitle":"DSC1121CE5-108.0000 Microchip MEMS XO 108 MHz CMOS AEC-Q100","metaDescription":"DSC1121CE5-108.0000 Microchip MEMS oscillator, 108 MHz CMOS output, 2.25V–3.6V supply, ±10 ppm stability, AEC-Q100.

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."},{"question":"Is DSC1121CE5-108.0000 AEC-Q100 qualified?","answer":"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."},{"question":"Can DSC1121CE5-108.0000 replace a quartz oscillator?","answer":"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."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/microchip/DSC1121CE5-108.0000","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/microchip/DSC1121CE5-108.0000 when reusing this data.
