Supply voltage spans 2.25V to 3.6V, making it compatible with 2.5V and 3.3V logic rails without an external regulator. ## Package and board-fit details Housed in a 6-VDFN with exposed pad (7.00mm x 5.00mm footprint, 0.90mm seated height), the DSC1121AM1-029.4912 is a surface-mount oscillator that requires a thermal pad on the PCB for heat dissipation — the exposed paddle should be soldered to a ground plane to keep junction temperature within the MIL-temp rating. No minimum order quantity beyond standard reel increments.","metaTitle":"DSC1121AM1-029.4912 Microchip MEMS XO 29.4912 MHz CMOS","metaDescription":"Active MEMS oscillator, 29.4912 MHz CMOS output, ±50ppm stability, 2.25V-3.6V supply, -55°C~125°C range. 6-VDFN 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":"29.4912 MHz","Mounting Type":"Surface Mount","Base Resonator":"MEMS","Package / Case":"6-VDFN 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":"Where can I buy DSC1121AM1-029.4912 and how do I get a price?","answer":"No stock-holding claim is made — each lot is sourced per request."},{"question":"Does DSC1121AM1-029.4912 have an enable/disable function?","answer":"Yes — the Enable/Disable function is listed.
