Supply voltage spans 2.25V to 3.6V, so the same BOM line works on a 2.5V or 3.3V rail without a separate regulator — just confirm the LVPECL termination voltage matches the receiver's Vcco. Startup time for MEMS oscillators is typically under 5 ms, compared to 10–20 ms for a quartz XO — the Enable/Disable function lets the system gate the clock without waiting for a long crystal warm-up. The 6-SMD no-lead package (3.20 mm x 2.50 mm x 0.90 mm) is a standard MEMS oscillator footprint shared across the DSC1122 family, so a pin-compatible frequency change (e.g., 50 MHz or 100 MHz) uses the same PCB land pattern.","metaTitle":"DSC1122CI5-048.0000 MEMS XO, LVPECL, 48 MHz, ±10 ppm","metaDescription":"Microchip DSC1122CI5-048.0000: 48 MHz LVPECL MEMS oscillator, ±10 ppm stability, 2.25V-3.6V supply, industrial temp.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Crystals & Oscillators"],"specifications":{"Mfr":"Microchip Technology","Type":"XO (Standard)","Output":"LVPECL","Series":"DSC1122","Package":"Tube","Ratings":"-","Function":"Enable/Disable","Frequency":"48 MHz","Mounting Type":"Surface Mount","Base Resonator":"MEMS","Package / Case":"6-SMD, No Lead","Product Status":"Active","lifecycle_stage":"eol_hot","Size / Dimension":"0.126\\\" L x 0.098\\\" W (3.20mm x 2.50mm)","Voltage - Supply":"2.25V ~ 3.6V","Base Product Number":"DSC1122","Frequency Stability":"±10ppm","Height - Seated (Max)":"0.035\\\" (0.90mm)","Operating Temperature":"-40°C~85°C","Current - Supply (Max)":"58mA","Absolute Pull Range (APR)":"-","Spread Spectrum Bandwidth":"-","Current - Supply (Disable) (Max)":"22mA"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/9eb455e34e1b4ad4aed847bfc84d48fa.pdf","sourceUrl":null},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/microchip/DSC1122CI5-048.0000","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/microchip/DSC1122CI5-048.0000 when reusing this data.
