Supply voltage spans 2.25 V to 3.63 V, so the same BOM line works across 2.5 V and 3.3 V rails without a separate regulator or level translator — the oscillator draws 40 mA typical (max) when enabled, and 23 mA typical in disable mode with the output tri-stated. Microchip lists the DSC1224CI3-350M0000 as Active.","metaTitle":"DSC1224CI3-350M0000 Microchip MEMS XO 350 MHz HCSL Active","metaDescription":"Microchip DSC1224CI3-350M0000 XO MEMS oscillator, 350 MHz HCSL output, ±20ppm stability, -40°C to 85°C, 6-VDFN.

The MEMS resonator is self-contained; the HCSL output is differential and compatible with PCIe clock inputs. Verify the supply voltage (2.25 V–3.63 V) and the enable/disable logic polarity match the existing socket."},{"question":"Does DSC1224CI3-350M0000 require external components like load capacitors?","answer":"No. The MEMS resonator and oscillator circuit are integrated inside the package. No external load capacitors, feedback resistors, or bias components are needed — the only external connections are the supply, ground, and the output trace."},{"question":"Can DSC1224CI3-350M0000 operate at 3.3V even though it has a range?","answer":"Yes — the supply range is 2.25 V to 3.63 V, so 3.3 V is well within the operating window. The same part also runs at 2.5 V without any configuration change. The enable/disable function is active on the OE pin."},{"question":"What is the recommended footprint for DSC1224CI3-350M0000?","answer":"The 6-VDFN package measures 3.20 mm x 2.50 mm with a seated height of 0.90 mm max. Microchip's datasheet provides the recommended land pattern; the pad layout is the same as for standard 6-pin DFN oscillators. The enable/disable pin (OE) is on pin 1 — leave it floating or pull high for output, ground to disable."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/microchip/DSC1224CI3-350M0000","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/microchip/DSC1224CI3-350M0000 when reusing this data.
