Supply voltage range is 2.5V to 3.3V, covering the common 2.5V and 3.3V rails on networking and computing boards — the Enable/Disable function lets the system gate the clock during low-power sleep states. Housed in a 6-VDFN package measuring 2.50mm x 2.00mm with a seated height of 0.90mm — the small footprint fits dense PCB layouts, but the 6-pin VDFN requires a solder-paste stencil aperture matched to the exposed pad for reliable reflow. Frequency stability is ±20ppm over the full temperature range — tight enough for most 100 MHz system clocks, though a PCIe Gen3 or Gen4 reference clock typically requires ±100ppm or better, so this part meets that margin comfortably.","metaTitle":"DSC1224DI3-100.0000 MEMS XO, HCSL, 100 MHz, Active","metaDescription":"Microchip DSC1224DI3-100.0000: Standard XO with MEMS resonator, HCSL output, 100 MHz, ±20ppm stability, 2.5V-3.3V supply, -40°C to 85°C, 6-VDFN.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Crystals & Oscillators"],"specifications":{"Mfr":"Microchip Technology","Type":"XO (Standard)","Output":"HCSL","Series":"DSC12X4","Package":"Tube","Ratings":"-","Function":"Enable/Disable","Frequency":"100 MHz","Mounting Type":"Surface Mount","Base Resonator":"MEMS","Package / Case":"6-VDFN","Product Status":"Active","lifecycle_stage":"eol_hot","Size / Dimension":"0.098\\\" L x 0.079\\\" W (2.50mm x 2.00mm)","Voltage - Supply":"2.5V ~ 3.3V","Frequency Stability":"±20ppm","Height - Seated (Max)":"0.035\\\" (0.90mm)","Operating Temperature":"-40°C ~ 85°C","Current - Supply (Max)":"40mA (Typ)","Absolute Pull Range (APR)":"-","Spread Spectrum Bandwidth":"-","Current - Supply (Disable) (Max)":"23mA (Typ)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/9c9562275ed01929df10cd035ac9614e.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is DSC1224DI3-100.0000 a MEMS oscillator?","answer":"Yes, the base resonator is MEMS, not quartz — the oscillator uses a silicon MEMS die as the resonant element."},{"question":"What is the output type of DSC1224DI3-100.0000?","answer":"The output is HCSL (High-Speed Current Steering Logic), the differential standard for PCIe reference clocks."},{"question":"Can DSC1224DI3-100.0000 be used as a replacement for a quartz oscillator?","answer":"Functionally yes — it is a drop-in XO replacement for a 100 MHz HCSL quartz oscillator in the same 6-VDFN footprint, but the MEMS resonator has different jitter and phase-noise characteristics, so verify the system's timing budget before substitution."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/microchip/DSC1224DI3-100.0000","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/microchip/DSC1224DI3-100.0000 when reusing this data.
