The CMOS output is a direct drop-in for any 24 MHz clock input that expects a square-wave reference — no external load capacitors or feedback resistor needed. Supply voltage spans 2.25V to 3.6V, so the oscillator runs on a 2.5V, 3.0V, or 3.3V rail without a separate regulator. ## Stability and temperature — outdoor and industrial margin For a 24 MHz carrier, that is a maximum deviation of ±600 Hz — well within the capture range of most PLL-based clock trees and Ethernet PHY reference inputs. The 6-SMD no-lead package measures 2.50 mm × 2.00 mm, a common footprint that fits the same PCB land pattern as many quartz oscillators of similar size. ## Sourcing and lifecycle — active with no LTB pressure Microchip lists the DSC1121DI2-024.0000 as Active.","metaTitle":"DSC1121DI2-024.0000 MEMS XO 24 MHz CMOS ±25 ppm -40°C to","metaDescription":"Microchip DSC1121DI2-024.0000 — 24 MHz MEMS oscillator, CMOS output, 2.25V–3.6V supply, ±25 ppm stability, -40°C to +85°C, 6-SMD no-lead 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":"24 MHz","Mounting Type":"Surface Mount","Base Resonator":"MEMS","Package / Case":"6-SMD, No Lead","Product Status":"Active","lifecycle_stage":"eol_hot","Size / Dimension":"0.098\\\" L x 0.079\\\" W (2.50mm x 2.00mm)","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)":"22mA","Absolute Pull Range (APR)":"-","Spread Spectrum Bandwidth":"-","Current - Supply (Disable) (Max)":"-"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.0350","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/4ad75d2f22fe92055f4a953b00c76a2c.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Can DSC1121DI2-024.0000 replace a standard 24 MHz quartz oscillator?","answer":"Yes — the MEMS-based DSC1121DI2-024.0000 is a functional replacement for a standard 24 MHz quartz oscillator with CMOS output. It does not require external load capacitors or a feedback resistor, and the 2.50 mm × 2.00 mm 6-SMD no-lead package matches many common quartz oscillator footprints. Verify the pinout and enable polarity against your existing quartz part before committing the BOM."},{"question":"Is DSC1121DI2-024.0000 compatible with 3.3V systems?","answer":"Yes — the supply voltage range is 2.25V to 3.6V, so a 3.3V rail is within the operating envelope.
