The 2.25V to 3.6V supply range covers 2.5V and 3.3V rails commonly found in mixed-voltage designs — no separate regulator is needed for the oscillator if the rail is within that band. ## Active production — sourcing to order Listed as Active by Microchip Technology, the DSC1121CL1-027.0000 is in ongoing production and suitable for new designs. The 3.20mm x 2.50mm footprint is standard for 6-SMD oscillators — no special layout accommodation is required beyond the usual keep-out zone under the package.","metaTitle":"DSC1121CL1-027.0000 MEMS XO 27 MHz CMOS - Microchip","metaDescription":"Active XO (Standard) with MEMS resonator, 27 MHz CMOS output, ±50 ppm stability, -40°C to 105°C, 6-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":"DSC1121","Package":"Tube","Ratings":"-","Function":"Enable/Disable","Frequency":"27 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":"±50ppm","Height - Seated (Max)":"0.035\\\" (0.90mm)","Operating Temperature":"-40°C~105°C","Current - Supply (Max)":"22mA","Absolute Pull Range (APR)":"-","Spread Spectrum Bandwidth":"-","Current - Supply (Disable) (Max)":"-"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.0500","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/4ad75d2f22fe92055f4a953b00c76a2c.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/DSC1121CL1-027.0000/alternatives.json"},"ai":{"faq":[{"question":"Does DSC1121CL1-027.0000 have an enable/disable function?","answer":"Yes, the function is listed as Enable/Disable.
