Its AEC-Q100 rating means it has passed the automotive-grade reliability stress tests — temperature cycling, ESD, and latch-up — making it suitable for under-hood and cabin electronics where a quartz crystal might crack under vibration. The wide 2.25V–3.6V supply means it can run directly off a 2.5V or 3.3V rail without an extra LDO, simplifying the power tree on a mixed-voltage board. ## Active production — design-in ready Listed as Active by Microchip, the DSC1121NI1-065.0000 is available for new designs. No end-of-life notice or successor has been issued — this is a current-production part, not a last-time-buy candidate. ## 6-SMD no-lead package — layout notes Housed in a 7.00 mm x 5.00 mm 6-SMD no-lead package (0.90 mm seated height), the DSC1121NI1-065.0000 uses a standard oscillator footprint. The enable/disable function on pin 1 lets a GPIO or power supervisor gate the clock without an external buffer — useful for power-cycled subsystems in automotive ECUs.","metaTitle":"DSC1121NI1-065.0000 MEMS Oscillator","metaDescription":"Microchip DSC1121NI1-065.0000 XO (Standard) MEMS oscillator, 65 MHz CMOS output, AEC-Q100 automotive qualified, -40°C 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":"Tube","Ratings":"AEC-Q100","Function":"Enable/Disable","Frequency":"65 MHz","Mounting Type":"Surface Mount","Base Resonator":"MEMS","Package / Case":"6-SMD, No Lead","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":null,"stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/4ad75d2f22fe92055f4a953b00c76a2c.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Does DSC1121NI1-065.0000 meet automotive AEC-Q100 standards?","answer":"Yes, it carries AEC-Q100 ratings, meaning it has passed the automotive-grade qualification for temperature cycling, ESD, and latch-up immunity. This qualifies it for under-hood and cabin electronics in passenger and commercial vehicles."},{"question":"What is the difference between DSC1121NI1-065.0000 and a standard quartz oscillator?","answer":"The DSC1121NI1-065.0000 uses a MEMS resonator instead of a quartz crystal. MEMS oscillators are inherently more resistant to shock and vibration — a common failure mode in automotive and industrial environments — and they start up faster (typically under 5 ms) with no frequency overshoot. The trade-off is that quartz can offer tighter stability (±20 ppm or better) for precision timing, but the ±50 ppm of this part covers most MCU, FPGA, and PHY clocking needs."},{"question":"What is the output type and supply voltage range for DSC1121NI1-065.0000?","answer":"Output is CMOS (rail-to-rail swing), and the supply voltage range is 2.25V to 3.6V.
