AEC-Q100 qualification certifies the part for automotive reliability stress and PPAP — a necessary gate for under-hood or chassis-domain designs. The 2.25V–3.6V supply range covers the common 2.5V and 3.3V logic rails without an external LDO — the oscillator's internal regulator rejects supply ripple up to the PSRR of the MEMS PLL. ## Frequency stability and temperature range A ±50 ppm window at 50 MHz is ±2.5 kHz; for a UART bit clock at 115.2 kbaud that is less than 0.5% of the bit period, so no issue. The part is in production and suitable for new designs. Sourced through independent distribution; confirmed at RFQ against the BOM quantity. No stock-holding claim — availability and current pricing are quoted per order.","metaTitle":"DSC1121CM1-050.0000T Microchip MEMS XO 50 MHz CMOS AEC-Q100","metaDescription":"DSC1121CM1-050.0000T: Microchip DSC1121 series MEMS oscillator, 50 MHz CMOS output, 2.25V–3.6V supply, ±50 ppm stability, -55°C to +125°C, AEC-Q100.","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":"50 MHz","Mounting Type":"Surface Mount","Base Resonator":"MEMS","Package / Case":"6-SMD, No Lead","Product Status":"Active","lifecycle_stage":"eol_hot","Size / Dimension":"0.126\\\" L x 0.098\\\" W (3.20mm x 2.50mm)","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":"$1.9400","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/4ad75d2f22fe92055f4a953b00c76a2c.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is DSC1121CM1-050.0000T AEC-Q100 qualified?","answer":"Yes, it carries AEC-Q100 qualification, which means it has passed automotive-grade reliability stress testing and is PPAP-ready for under-hood or chassis-domain applications."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/microchip/DSC1121CM1-050.0000T","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/microchip/DSC1121CM1-050.0000T when reusing this data.
