Combined with a MEMS base resonator, the part survives the shock and vibration profile of a transmission-mounted sensor module better than a quartz can. ## Supply voltage tolerance and output drive Operates from 2.25V to 3.6V with CMOS output — drop it onto a 2.5V or 3.3V rail without a separate LDO. 6-SMD, No Lead Exposed Pad package, 7.00mm x 5.00mm body, 0.90mm seated height. Surface-mount on a standard FR-4 board; the exposed pad helps conduct heat to the ground plane. No official second-source or pin-compatible drop-in from another manufacturer, but the DSC1121 series has multiple frequency variants if you need a different clock speed in the same footprint.","metaTitle":"DSC1121AM1-033.0000 MEMS Oscillator – 33 MHz, CMOS, AEC-Q100","metaDescription":"Microchip DSC1121AM1-033.0000 XO (Standard) with MEMS resonator, 33 MHz CMOS output, ±50 ppm stability, AEC-Q100 qualified, -55°C to 125°C.","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":"33 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":"±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":"Is DSC1121AM1-033.0000 a direct replacement for a quartz oscillator in the same footprint?","answer":"Pin-compatible with standard 7.0mm x 5.0mm 6-pad quartz oscillators. The MEMS resonator inside is more shock-tolerant than quartz, so it can replace a quartz part in a high-vibration environment without a board spin — but confirm the Enable/Disable logic polarity matches your existing circuit."},{"question":"Can I use this oscillator at 125°C continuously?","answer":"Yes — the -55°C to 125°C rating covers continuous operation.
