The wide supply range from 2.25V to 3.6V means a single DSC1121CI2-148.5000 can run from a 3.3V or 2.5V rail without a dedicated LDO — useful for mixed-voltage systems where the core SoC runs 1.8V and the I/O bank is 3.3V. Housed in a 6-SMD, No Lead package measuring 3.20 mm x 2.50 mm with a seated height of 0.90 mm — this is a standard 3.2 x 2.5 mm ceramic oscillator footprint, so the PCB pad layout and solder stencil aperture are well-documented and easily sourced. Surface-mount assembly with no leads means the thermal pad is the bottom of the package; the reflow profile follows standard lead-free solder recommendations for ceramic SMD oscillators.","metaTitle":"DSC1121CI2-148.5000 MEMS Oscillator 148.5 MHz CMOS AEC-Q100","metaDescription":"Microchip DSC1121CI2-148.5000 XO (Standard) MEMS oscillator, 148.5 MHz CMOS output, ±25 ppm stability, 2.25V-3.6V supply, AEC-Q100 qualified, -40°C to +85°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":"148.5 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":"±25ppm","Height - Seated (Max)":"0.035\\\" (0.90mm)","Operating Temperature":"-40°C~85°C","Current - Supply (Max)":"35mA","Absolute Pull Range (APR)":"-","Spread Spectrum Bandwidth":"-","Current - Supply (Disable) (Max)":"22mA"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.5750","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/4ad75d2f22fe92055f4a953b00c76a2c.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is DSC1121CI2-148.5000 compatible with a 3.3V supply?","answer":"Yes.
