It is not rated for the -40°C floor of industrial or automotive environments. Housed in a 20-VFQFN with exposed pad (5.00 mm x 3.20 mm body, 0.90 mm height), the package requires a thermal pad on the PCB for heat sinking — the exposed paddle must be soldered to a ground plane pour to keep junction temperatures in check.","metaTitle":"DSC400-3333Q0094KE1 MEMS XO – 125/100/100/50 MHz LVDS","metaDescription":"Microchip DSC400-3333Q0094KE1: MEMS-based XO, 4 LVDS outputs (125/100/100/50 MHz), ±50 ppm, 2.25-3.6 V, -20 to 70°C, 20-QFN.

Submit an RFQ with your target quantity and target price; we will confirm availability and lead time from our independent distribution channels. No stock level is published here — pricing and delivery are quoted per order."},{"question":"What is the frequency stability of DSC400-3333Q0094KE1?","answer":"±50 ppm across the full -20°C to 70°C range. That is tight enough for most 1 GbE and PCIe Gen 1/2 reference clocks; for Gen 3 or 25 GbE you would typically look for ±25 ppm or better."},{"question":"Is there a pin-compatible alternative in the DSC400 family?","answer":"The DSC400 series shares the same 20-VFQFN footprint and pinout across multiple frequency configurations. A different ordering code (same base number DSC400) with the same supply and output type will drop in — confirm the output frequencies match your clock tree before swapping."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/microchip/DSC400-3333Q0094KE1","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/microchip/DSC400-3333Q0094KE1 when reusing this data.
