The DSC1122 family is a current product line; the datasheet and application notes are available from Microchip.","metaTitle":"DSC1122CI5-071.0000 MEMS XO, LVPECL, 71MHz, ±10ppm","metaDescription":"Microchip DSC1122CI5-071.0000 XO (Standard) with MEMS resonator, LVPECL output at 71 MHz, ±10ppm stability, industrial temp range.","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":"71 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":[{"question":"Is DSC1122CI5-071.0000 a replacement for quartz oscillators?","answer":"Yes — the MEMS base resonator is a drop-in replacement for quartz-based XOs in the same 6-SMD, No Lead footprint. The LVPECL output is a differential signal, so the downstream receiver must be LVPECL-compatible; if your board uses a CMOS or LVDS clock input, you need a different output option from the DSC1122 family. The ±10ppm stability is tighter than most quartz oscillators, so the replacement may actually improve timing margin."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/microchip/DSC1122CI5-071.0000","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/microchip/DSC1122CI5-071.0000 when reusing this data.
