Microchip lists the DSC400-3333Q0078KI1T as Active.","metaTitle":"DSC400-3333Q0078KI1T MEMS XO, LVDS, 125 MHz x4, Active","metaDescription":"Microchip DSC400-3333Q0078KI1T: MEMS-based XO, 4x 125 MHz LVDS outputs, ±50 ppm stability, -40°C to 85°C, 20-VFQFN.

The supply voltage range is 2.25 V to 3.6 V, so it runs directly from a 3.3 V rail without an additional regulator. The LVDS outputs swing 350 mV typical into a 100-ohm termination, compatible with standard LVDS receivers on FPGAs and ASICs at 3.3 V."},{"question":"Does DSC400-3333Q0078KI1T have an enable/disable function?","answer":"Yes, the enable/disable function is built in. When disabled, the outputs enter a high-impedance state, which allows bus-sharing or power-down clock gating without a separate clock buffer."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/microchip/DSC400-3333Q0078KI1T","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/microchip/DSC400-3333Q0078KI1T when reusing this data.
