Procurement teams for Tier-1 automotive or high-reliability industrial programs can treat this as a qualified drop-in without an additional PPAP review cycle. The MEMS resonator eliminates quartz start-up delay and offers superior shock/vibration tolerance — the output is stable within microseconds of power-up, and the part holds frequency through mechanical shock events that would cause a quartz oscillator to glitch. Housed in a 6-VDFN package measuring 5.00 mm × 3.20 mm with a seated height of 0.90 mm, this is a standard 5.0×3.2 mm oscillator footprint. The Enable/Disable function is typically on pin 1 — when pulled low, the output goes to high-impedance and the current drops to 22 mA. Leave pin 1 floating or tie it high for normal operation. For volume requirements, confirm reel or tape-and-reel availability at quote time — the base product number DSC1121 may have alternative packaging suffixes.","metaTitle":"DSC1121BM1-125.0000 MEMS XO – 125 MHz, AEC-Q100","metaDescription":"Microchip DSC1121BM1-125.0000: 125 MHz MEMS oscillator, CMOS output, ±50 ppm stability, 2.25–3.6 V 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":"125 MHz","Mounting Type":"Surface Mount","Base Resonator":"MEMS","Package / Case":"6-VDFN","Product Status":"Active","lifecycle_stage":"eol_hot","Size / Dimension":"0.197\\\" L x 0.126\\\" W (5.00mm x 3.20mm)","Voltage - Supply":"2.25V ~ 3.6V","Base Product Number":"DSC1121","Frequency Stability":"±50ppm","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":"What is the closest pin-compatible alternative in the DSC1121 family?","answer":"Any DSC1121-series oscillator in the same 6-VDFN package and with the same Enable/Disable function is pin-compatible.
