Each output can be configured as LVCMOS or LVDS, giving the layout engineer flexibility to drive both single-ended logic and differential pairs from the same device. The enable/disable function lets firmware bring unused output domains into high-Z during sleep modes, cutting system power without a dedicated load switch. ## ±25 ppm stability across industrial temperature range Frequency stability is rated at ±25 ppm over the full -40 to 85°C industrial temperature range — tight enough for a 12 MHz reference feeding an Ethernet PHY or a 50 MHz clock for a high-speed ADC without external trimming. ## Wide supply range simplifies rail selection Operating from 2.25 V to 3.6 V, this oscillator can run directly off a 2.5 V or 3.3 V rail without an intermediate LDO — one less part to qualify and one less dropout voltage to budget. The 20-VFQFN exposed-pad package (5.0×3.2 mm, 0.90 mm height) is a standard footprint; the thermal pad should be soldered to a ground plane for heat sinking, especially if all four outputs are driving 50 MHz into capacitive loads.","metaTitle":"DSC400-3331Q0098KI2 MEMS XO – 12/50/50/50 MHz, LVCMOS/LVDS","metaDescription":"Microchip DSC400-3331Q0098KI2: MEMS-based XO, 4 outputs (12+3×50 MHz), ±25 ppm, -40 to 85°C, 2.25-3.6V.

For LVDS outputs, place a 100-ohm termination resistor across the differential pair close to the receiver. For LVCMOS outputs, the trace impedance should match the driver's output impedance (typically 50 ohms) to avoid reflections."},{"question":"Is DSC400-3331Q0098KI2 compatible with a 2.5V supply?","answer":"Yes, the supply range is 2.25 V to 3.6 V, so a 2.5 V rail is within spec. The output swing will be rail-relative — LVCMOS levels scale with Vdd, and LVDS common-mode voltage shifts accordingly."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/microchip/DSC400-3331Q0098KI2","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/microchip/DSC400-3331Q0098KI2 when reusing this data.
