Each output can be independently configured as LVCMOS or LVDS, letting the same device drive both a low-speed MCU clock (LVCMOS) and a high-speed SerDes reference (LVDS) without a level translator. The 2.25 V to 3.6 V supply range covers common 2.5 V and 3.3 V rails without an external LDO — one less part to qualify. ## Temperature grade and deployment fit This suits indoor telecom switches, networking equipment, office automation, and test instrumentation where ambient stays within a conditioned space.","metaTitle":"DSC400-3331Q0097KE1T MEMS XO – 16/50/50/50 MHz, LVCMOS/LVDS","metaDescription":"Microchip DSC400 quad-output MEMS oscillator: 16 MHz + 3× 50 MHz, ±50 ppm, LVCMOS/LVDS, Enable/Disable, 20-VFQFN, -20°C~70°C.

The part is Active and sourced through independent distribution — we confirm availability and pricing per your BOM quantity at quote time. No stock-holding claim is made here; the quote reflects real-time supply."},{"question":"Does the DSC400-3331Q0097KE1T have an enable/disable function?","answer":"Yes, the function is Enable/Disable. Pulling the OE pin low tri-states the outputs, which lets you gate the clock tree during system sleep without an external load switch."},{"question":"What is the difference between DSC400-3331Q0097KE1T and DSC400-3331Q0097KE1?","answer":"The suffix 'T' indicates Tape & Reel (TR) packaging. The 'KE1' variant without the 'T' suffix is typically supplied in a different carrier — tube or tray — but the electrical specifications are identical. Confirm the reel quantity and carrier format with your RFQ."},{"question":"Is the DSC400-3331Q0097KE1T RoHS compliant?","answer":"RoHS compliance is standard for the DSC400 series from Microchip. The 20-VFQFN package is lead-free and compatible with lead-free reflow profiles. No separate RoHS certificate is required for this order code."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/microchip/DSC400-3331Q0097KE1T","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/microchip/DSC400-3331Q0097KE1T when reusing this data.
