The DSC400 series is the base product number; the -3111Q0088KI2 suffix encodes the factory-programmed frequency plan and output format. Order the exact suffix — the base part alone is not field-programmable. Housed in a 20-VFQFN with exposed pad (5.00 x 3.20 mm body, 0.90 mm height), the thermal pad must be soldered to a ground-plane island for heat sinking.","metaTitle":"DSC400-3111Q0088KI2 MEMS XO – 4 outputs, 12–148.25 MHz","metaDescription":"Microchip DSC400-3111Q0088KI2: MEMS XO, LVCMOS/LVDS, 4 independent frequencies (148.25 MHz, 12/24 MHz, 25/100 MHz), ±25 ppm, industrial temp, active.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Crystals & Oscillators"],"specifications":{"Mfr":"Microchip Technology","Type":"XO (Standard)","Height":"0.035\\\" (0.90mm)","Output":"LVCMOS, LVDS","Series":"DSC400","Package":"Tube","Function":"Enable/Disable","Base Resonator":"MEMS","Package / Case":"20-VFQFN Exposed Pad","Product Status":"Active","lifecycle_stage":"eol_hot","Size / Dimension":"0.197\\\" L x 0.126\\\" W (5.00mm x 3.20mm)","Voltage - Supply":"2.25V ~ 3.6V","Base Product Number":"DSC400","Frequency Stability":"±25ppm","Frequency - Output 1":"148.25MHz","Frequency - Output 2":"12MHz, 24MHz","Frequency - Output 3":"25MHz, 100MHZ","Frequency - Output 4":"148.25MHz","Operating Temperature":"-40°C~85°C","Current - Supply (Max)":"-"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/2723b9747a2eae277fa05951882c31f9.pdf","sourceUrl":null},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/microchip/DSC400-3111Q0088KI2","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/microchip/DSC400-3111Q0088KI2 when reusing this data.
