Its AEC-Q100 rating means it has passed the full automotive IC qualification suite — temperature cycling, ESD, latch-up, and reliability stress — making it suitable for under-hood and cabin electronics where a standard quartz oscillator would not meet the PPAP documentation requirement. ## Supply voltage and temperature range for automotive and industrial use The supply voltage range spans 2.25V to 3.6V, so this oscillator can be powered directly from a 2.5V or 3.3V rail without a dedicated LDO — a single rail simplifies the BOM for an ECU or telematics unit. ## MEMS resonator vs. quartz — vibration and reliability advantage The base resonator is MEMS rather than quartz. MEMS oscillators have inherently higher shock and vibration tolerance than quartz crystals, which matters for engine-bay and chassis-mounted ECUs that see 50 g mechanical shock. The Enable/Disable function lets the system pull the output to high-Z and drop supply current from 35 mA to 22 mA during sleep modes. ## Active lifecycle — design-in ready The product status is Active.","metaTitle":"DSC1121AI1-025.0000T – Microchip MEMS XO, 25 MHz, AEC-Q100","metaDescription":"DSC1121AI1-025.0000T – Microchip DSC1121 series MEMS oscillator, 25 MHz, CMOS output, AEC-Q100 qualified, -40 to 85°C, 2.25-3.6V supply.","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":"Tape & Reel (TR)","Ratings":"AEC-Q100","Function":"Enable/Disable","Frequency":"25 MHz","Mounting Type":"Surface Mount","Base Resonator":"MEMS","Package / Case":"6-SMD, No Lead Exposed Pad","Product Status":"Active","lifecycle_stage":"eol_hot","Size / Dimension":"0.276\\\" L x 0.197\\\" W (7.00mm x 5.00mm)","Voltage - Supply":"2.25V ~ 3.6V","Base Product Number":"DSC1121","Frequency Stability":"±50ppm","Height - Seated (Max)":"0.035\\\" (0.90mm)","Operating Temperature":"-40°C~85°C","Current - Supply (Max)":"35mA","Absolute Pull Range (APR)":"-","Spread Spectrum Bandwidth":"-","Current - Supply (Disable) (Max)":"22mA"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.0350","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/4ad75d2f22fe92055f4a953b00c76a2c.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is DSC1121AI1-025.0000T AEC-Q100 qualified?","answer":"Yes, it carries an AEC-Q100 rating.
