Rated AEC-Q100, this oscillator is qualified for automotive applications where reliability screening and temperature cycling are required — suitable for infotainment, ADAS camera modules, and body-control ECU clock trees. ## Supply voltage flexibility and power management The 2.25V to 3.6V supply range covers both 2.5V and 3.3V logic rails without an external regulator — a single part serves mixed-voltage designs. An Enable/Disable pin (active-high) lets the system gate the oscillator output, dropping supply current from 35 mA max to 22 mA max in the disabled state — useful for sleep-mode power budgets in battery-backed modules. ## Package and mounting for production Housed in a 6-SMD, No Lead package measuring 3.20mm x 2.50mm with a seated height of 0.90mm, the DSC1121CE2-100.0000 is a surface-mount component compatible with standard reflow profiles and automated pick-and-place assembly. The MEMS base resonator eliminates the quartz crystal start-up time and vibration sensitivity typical of conventional oscillators — a practical advantage in automotive and industrial environments where mechanical shock is present. The part is quoted to order — no stock-holding claim is made.","metaTitle":"DSC1121CE2-100.0000 MEMS Oscillator – 100 MHz, CMOS","metaDescription":"Microchip DSC1121CE2-100.0000 XO (Standard) MEMS oscillator, 100 MHz CMOS output, ±25ppm stability, 2.25V-3.6V supply, AEC-Q100 qualified.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Crystals & Oscillators"],"specifications":{"Mfr":"Microchip Technology","Type":"XO (Standard)","Output":"CMOS","Series":"DSC1121","Package":"Tube","Ratings":"AEC-Q100","Function":"Enable/Disable","Frequency":"100 MHz","Mounting Type":"Surface Mount","Base Resonator":"MEMS","Package / Case":"6-SMD, No Lead","Product Status":"Active","lifecycle_stage":"eol_hot","Size / Dimension":"0.126\\\" L x 0.098\\\" W (3.20mm x 2.50mm)","Voltage - Supply":"2.25V ~ 3.6V","Base Product Number":"DSC1121","Frequency Stability":"±25ppm","Height - Seated (Max)":"0.035\\\" (0.90mm)","Operating Temperature":"-20°C~70°C","Current - Supply (Max)":"35mA","Absolute Pull Range (APR)":"-","Spread Spectrum Bandwidth":"-","Current - Supply (Disable) (Max)":"22mA"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/4ad75d2f22fe92055f4a953b00c76a2c.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is DSC1121CE2-100.0000 AEC-Q100 qualified?","answer":"Yes, the DSC1121CE2-100.0000 carries an AEC-Q100 rating, qualifying it for automotive-grade applications requiring the associated reliability stress and temperature cycling tests."},{"question":"Does DSC1121CE2-100.0000 have an enable/disable feature?","answer":"Yes, the DSC1121CE2-100.0000 includes an Enable/Disable function.
