The supply voltage range is 2.25V to 3.6V, so a 2.5V rail is within spec. No external regulator is required."},{"question":"Can I replace a quartz oscillator with this MEMS oscillator on the same PCB footprint?","answer":"The DSC1124BE2-100.0000 uses a standard 5.00 mm x 3.20 mm 6-SMD no-lead package, which matches the footprint of many quartz oscillators of the same size. However, MEMS oscillators typically have different decoupling and output termination requirements — review the Microchip application note for the DSC1124 family before substituting."},{"question":"Does the DSC1124BE2-100.0000 require external load capacitors?","answer":"No. Because it is a MEMS-based oscillator (not a quartz crystal resonator), the output is a driven HCSL signal. No external load capacitors are needed at the output — the termination is a 50-ohm to ground or a Thevenin equivalent per the HCSL standard."},{"question":"How does the DSC1124BE2-100.0000 compare to a similar 100 MHz HCSL oscillator from another manufacturer?","answer":"The key differentiator is the MEMS resonator — it offers faster start-up and better shock/vibration tolerance than a quartz-based HCSL oscillator. The ±25 ppm stability and 2.25V–3.6V supply range are comparable to most quartz HCSL parts in the same 5×3.2 mm package. Pin compatibility depends on the specific pinout — confirm the Enable/Disable function and output type match the existing layout."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/microchip/DSC1124BE2-100.0000","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/microchip/DSC1124BE2-100.0000 when reusing this data.
