Runs on any rail from 2.25 V to 3.6 V, so it works with 2.5 V or 3.3 V supplies without an extra regulator. Product status is Active per Microchip's lifecycle record. Housed in a 20-VFQFN with exposed pad (5.00 mm × 3.20 mm footprint, 0.90 mm height).","metaTitle":"DSC400-3331Q0098KI1 MEMS XO – 4-Output LVCMOS/LVDS","metaDescription":"Microchip DSC400-3331Q0098KI1 MEMS XO: four independent outputs (12 MHz + 3×50 MHz), LVCMOS/LVDS, 2.25V–3.6V, -40°C–85°C, 20-VFQFN.

It provides the same clock function with better frequency stability (±50 ppm) over temperature and vibration. It is a drop-in replacement for a quartz oscillator in the same 20-VFQFN footprint, but check the output type (LVCMOS or LVDS) matches your receiver."},{"question":"What output types does the DSC400-3331Q0098KI1 support?","answer":"It supports both LVCMOS and LVDS outputs. The four outputs can be configured independently — the 12 MHz and three 50 MHz rails each can be set to either standard, giving you mixed single-ended and differential clocks from one device."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/microchip/DSC400-3331Q0098KI1","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/microchip/DSC400-3331Q0098KI1 when reusing this data.
