The MEMS resonator gives it an advantage over quartz in high-vibration environments — no piezoelectric crystal to crack under mechanical shock. Startup time is typically under 5 ms, compared to 10-20 ms for a quartz oscillator, which matters for fast-booting ECUs. Operates from a 2.25V to 3.6V supply, covering both 2.5V and 3.3V logic rails without an external regulator. CMOS output is a single-ended, rail-to-rail swing that interfaces directly with most MCU, FPGA, and PHY clock inputs. No external termination resistors are needed for short traces — the 15 pF load capacitance typical of CMOS inputs is well within the oscillator's drive capability. Housed in a 6-SMD, No Lead Exposed Pad package measuring 7.00 mm x 5.00 mm with a seated height of 0.90 mm. The 0.90 mm height allows it to fit under low-profile enclosures and mezzanine boards.","metaTitle":"DSC1121AM2-066.6660T – Microchip MEMS XO, 66.666 MHz","metaDescription":"Active Microchip DSC1121AM2-066.6660T MEMS oscillator: 66.666 MHz CMOS output, ±25 ppm stability, 2.25-3.6V 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":"Tape & Reel (TR)","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":"Is DSC1121AM2-066.6660T AEC-Q100 qualified?","answer":"Yes, the DSC1121AM2-066.6660T carries AEC-Q100 qualification, meaning it has passed automotive-grade reliability testing including temperature cycling, ESD, and latch-up immunity.
