Its ±10 ppm frequency stability over the -20°C to 70°C commercial range keeps the clock edge jitter within tight margins for 10/100/1000BASE-T applications without needing a TCXO. ## Supply and output compatibility LVPECL output requires DC-biased termination (typically Thevenin-equivalent 50 Ω to VCC-2 V) — the same termination works across the supply range, simplifying board layout. ## Package and footprint for 6-SMD assembly Housed in a 6-SMD no-lead package measuring 3.20 mm x 2.50 mm with a seated height of 0.90 mm — the compact footprint fits dense PCB layouts where a 5x7 mm quartz oscillator would crowd adjacent passives. ## Active production status and sourcing","metaTitle":"DSC1122CE5-048.0020T MEMS XO – 48.002 MHz LVPECL, Active","metaDescription":"Microchip DSC1122CE5-048.0020T MEMS oscillator: XO (Standard), 48.002 MHz LVPECL output, ±10 ppm stability, 2.25-3.6V supply, -20 to 70°C.","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":"Tape & Reel (TR)","Ratings":"-","Function":"Enable/Disable","Frequency":"48.002 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":"-20°C~70°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/DSC1122CE5-048.0020T","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/microchip/DSC1122CE5-048.0020T when reusing this data.
