The wide supply range of 2.25V to 3.6V lets you run the oscillator directly from a 2.5V or 3.3V rail without an extra LDO. Housed in a 6-SMD, No Lead package measuring 5.00 mm x 3.20 mm with a seated height of 0.90 mm, this oscillator fits standard 5x3.2 mm clock footprints. Surface-mount assembly is straightforward, but the small pad geometry calls for a controlled solder paste stencil to avoid bridging on the no-lead terminations.","metaTitle":"DSC1121BM2-007.3728 MEMS Oscillator","metaDescription":"DSC1121BM2-007.3728 from Microchip Technology: XO (Standard) MEMS oscillator, 7.3728 MHz, CMOS output, ±25 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":"7.3728 MHz","Mounting Type":"Surface Mount","Base Resonator":"MEMS","Package / Case":"6-SMD, No Lead","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":"±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,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/4ad75d2f22fe92055f4a953b00c76a2c.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/DSC1121BM2-007.3728/alternatives.json"},"ai":{"faq":[{"question":"Can the DSC1121BM2-007.3728 replace a standard quartz oscillator?","answer":"Yes, it is a drop-in replacement for many 7.3728 MHz quartz oscillators in the same 5.0 mm x 3.2 mm footprint, with the added benefit of MEMS reliability — better shock and vibration tolerance than quartz."},{"question":"What is the frequency stability of the DSC1121BM2-007.3728?","answer":"Frequency stability is ±25 ppm, sufficient for most microcontroller and communication clocking requirements."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/microchip/DSC1121BM2-007.3728","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/microchip/DSC1121BM2-007.3728 when reusing this data.
