AEC-Q100 qualification means this part is validated for automotive stress conditions, making it suitable for under-hood and chassis-mounted electronics where temperature cycling and vibration are routine. The MEMS resonator inherently withstands higher shock and vibration than a quartz crystal — a practical advantage in engine bays, drivetrain modules, and industrial motor drives where quartz can fracture or drift. ## Supply Voltage and Enable/Disable Function Operating from 2.25V to 3.6V, this oscillator can be powered directly from a 2.5V or 3.3V rail without an intermediate regulator, simplifying the power tree on mixed-voltage boards. The Enable/Disable function allows the output to be tri-stated, reducing supply current to 22 mA max when the clock is not needed — useful for power-sensitive designs that gate the oscillator during sleep modes. ## Package and Footprint Compatibility Housed in a 6-SMD, No Lead Exposed Pad package measuring 7.00mm x 5.00mm with a seated height of 0.90 mm, this footprint is a standard 7050 oscillator layout, directly compatible with many existing PCB designs and sockets.","metaTitle":"DSC1121AM2-066.6660 MEMS Oscillator – 66.666 MHz, AEC-Q100","metaDescription":"Microchip DSC1121AM2-066.6660 XO (Standard) MEMS oscillator, 66.666 MHz CMOS output, ±25 ppm stability, AEC-Q100 qualified, -55°C to 125°C.","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":"66.666 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":"±25ppm","Height - Seated (Max)":"0.035\\\" (0.90mm)","Operating Temperature":"-55°C~125°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":"Where can I buy the DSC1121AM2-066.6660 and get a price?","answer":"Submit an RFQ with your target quantity; we will confirm current pricing and availability against your order.
