Supply voltage spans 2.25 V to 3.6 V, so it runs on a 2.5 V or 3.3 V rail without an external regulator — just decouple the pin. ## Active and available through distribution It is a current-design part, not a last-time-buy candidate.","metaTitle":"DSC400-2222Q0104KE2 MEMS XO – 4 LVPECL Outputs, 2.25-3.6V","metaDescription":"Microchip DSC400-2222Q0104KE2 MEMS XO, 4 LVPECL outputs (125/100/200/156.25 MHz), ±25 ppm stability, 2.25-3.6V supply.

The supply voltage range is 2.25 V to 3.6 V, so a 3.3 V rail is within spec. No external regulator needed — just a bypass cap at the supply pin."},{"question":"What is the closest pin-compatible alternative to DSC400-2222Q0104KE2?","answer":"No pin-compatible alternative is listed in the DSC400 series for this exact frequency set. The DSC400 family shares the same 20-VFQFN footprint and supply range, but each order code has a unique output frequency combination. Verify the frequencies your BOM requires before substituting."},{"question":"What is the output type of DSC400-2222Q0104KE2?","answer":"LVPECL — low-voltage positive emitter-coupled logic. It requires 50-ohm termination to Vcc-2V at the receiver end, typical for high-speed clock distribution."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/microchip/DSC400-2222Q0104KE2","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/microchip/DSC400-2222Q0104KE2 when reusing this data.
