AEC-Q100 qualification confirms the part passed the automotive reliability stress suite: temperature cycling, ESD, and latch-up testing. Combined with the -55 to +125 °C operating range, this oscillator is suited for under-hood ECUs, ADAS sensor modules, and defence telemetry that must start and hold frequency across the full military temperature band. ## Supply rail and output compatibility The CMOS output swings rail-to-rail, so it drives most MCU and FPGA clock inputs directly; no level translation needed. Maximum supply current is 35 mA when enabled and 22 mA when disabled. The Enable/Disable function lets a system power-down the oscillator in sleep mode, cutting current draw by roughly 13 mA — useful in battery-operated or energy-harvesting designs where every milliwatt counts. It is a standard catalog part in the DSC1121 series, suitable for new designs and production ramp. The 6-SMD no-lead exposed pad package measures 7.00 mm × 5.00 mm with a seated height of 0.90 mm. The exposed pad under the package provides a thermal path to the PCB — a solid ground-plane via pattern under the pad improves heat dissipation and reduces frequency drift under load.","metaTitle":"DSC1121AM2-050.0000 MEMS XO – 50 MHz, AEC-Q100, -55 to 125°C","metaDescription":"Active-production MEMS oscillator, 50 MHz CMOS output, ±25 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":"50 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":"What is the frequency stability of the DSC1121AM2-050.0000?","answer":"The frequency stability is ±25 ppm across the full -55 to +125 °C range. That is tight enough for 100BASE-TX Ethernet reference clocks, CAN FD transceivers, and most MCU oscillator inputs without needing a TCXO."},{"question":"Can the DSC1121AM2-050.0000 replace a quartz crystal oscillator in an existing design?","answer":"This is a MEMS oscillator, not a bare crystal — it integrates the resonator and the drive circuit in one package. It can replace a quartz crystal oscillator (XO) with the same footprint, output type (CMOS), and supply voltage. The MEMS construction is inherently more resistant to shock and vibration than quartz, but the ±25 ppm stability is comparable to a standard quartz XO, not a TCXO. Check the pinout and enable polarity against your existing XO before substituting."},{"question":"Is the DSC1121AM2-050.0000 AEC-Q100 qualified?","answer":"Yes, it carries AEC-Q100 rating. That means it passed the automotive-grade stress tests: temperature cycling, biased HAST, ESD, and solder reflow reliability. It is suitable for use in safety-critical and under-hood automotive applications."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/microchip/DSC1121AM2-050.0000","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/microchip/DSC1121AM2-050.0000 when reusing this data.
