Housed in a 4-SMD, No Lead package measuring 3.20 mm x 2.50 mm with a seated height of 0.90 mm, the DSC1033CI2-012.5000 fits tight PCB layouts and is compatible with standard reflow soldering profiles. Surface-mount assembly requires no through-hole — the no-lead design reduces parasitic inductance compared to a leaded package, which helps maintain signal integrity at the output edge rate.","metaTitle":"DSC1033CI2-012.5000 MEMS Oscillator 12.5 MHz CMOS ±25 ppm","metaDescription":"DSC1033CI2-012.5000 Microchip Technology MEMS XO, 12.5 MHz CMOS output, ±25 ppm stability, 3.3 V, -40°C to 85°C, 4-SMD package.","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":"DSC1033, PureSilicon™","Package":"Tube","Ratings":"-","Function":"Standby (Power Down)","Frequency":"12.5 MHz","Mounting Type":"Surface Mount","Base Resonator":"MEMS","Package / Case":"4-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":"3.3V","Base Product Number":"DSC1033","Frequency Stability":"±25ppm","Height - Seated (Max)":"0.035\\\" (0.90mm)","Operating Temperature":"-40°C~85°C","Current - Supply (Max)":"10mA","Absolute Pull Range (APR)":"-","Spread Spectrum Bandwidth":"-","Current - Supply (Disable) (Max)":"1µA"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/39044fcc9825a23a0d54b2590f18614f.pdf","sourceUrl":null},"ai":{"faq":[{"question":"How does the DSC1033CI2-012.5000 compare to a quartz crystal oscillator?","answer":"The DSC1033CI2-012.5000 uses a MEMS resonator instead of a quartz crystal. MEMS oscillators typically offer faster startup, better shock and vibration resistance, and smaller package size compared to quartz-based XOs at the same frequency and stability grade. The ±25 ppm stability and 12.5 MHz output are functionally equivalent to a quartz oscillator for most digital clocking applications."},{"question":"What does the standby (power down) function do?","answer":"When the standby pin is asserted, the oscillator stops and draws only 1 µA (max) from the 3.3 V supply, compared to 10 mA in active mode. This allows the system to gate the clock to save power during sleep states without removing the supply rail."},{"question":"What is the closest pin-compatible alternative to the DSC1033CI2-012.5000?","answer":"Within the DSC1033 family, other frequency variants with the same package, supply voltage, and stability grade share the same pinout. For a direct functional equivalent at 12.5 MHz with CMOS output and ±25 ppm, the DSC1033CI2-012.5000 itself is the exact ordering code — no second-source or cross-reference is documented by Microchip."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/microchip/DSC1033CI2-012.5000","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/microchip/DSC1033CI2-012.5000 when reusing this data.
