The ±20 ppm frequency stability holds the timing budget for most serial-link applications without external trimming. The supply range spans 2.5 V to 3.3 V — a single BOM line covers both logic rails, simplifying inventory when the same design ships in 2.5 V and 3.3 V variants. ## MEMS vs quartz — the reliability advantage Start-up time is typically under 5 ms, compared to 10–20 ms for a quartz oscillator. The 6-VDFN package (7.0 mm × 5.0 mm, 0.9 mm seated height) is a standard footprint shared across the DSC1224 family, so a frequency change or a move to a different Microchip MEMS oscillator can reuse the same PCB layout. No pin-compatible equivalent from another manufacturer is confirmed; the DSC1224 series itself covers multiple frequencies and output types (LVDS, LVPECL, HCSL) in the same 6-VDFN footprint.","metaTitle":"DSC1224NL3-100M0000 – 100 MHz HCSL MEMS XO, -40°C to 105°C","metaDescription":"Microchip DSC1224NL3-100M0000 – 100 MHz HCSL output MEMS oscillator, ±20 ppm stability, 2.5V–3.3V supply, industrial temp.

The voltage supply range is 2.5 V to 3.3 V, so it operates on a 2.5 V rail without a separate regulator. The HCSL output levels scale with the supply voltage — confirm the receiver's input threshold at 2.5 V before committing the BOM."},{"question":"Can the DSC1224NL3-100M0000 replace a quartz oscillator in an existing design?","answer":"Functionally yes — it is a drop-in XO replacement in the same 6-VDFN footprint. The MEMS resonator gives better vibration immunity and faster start-up, but the output is HCSL, not LVCMOS. If the original design used a single-ended CMOS oscillator, the HCSL differential output requires a termination network (typically 50 Ω to ground per line) and the receiver must accept HCSL levels."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/microchip/DSC1224NL3-100M0000","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/microchip/DSC1224NL3-100M0000 when reusing this data.
