LVPECL output draws 58 mA max — the dominant current is the output stage, not the MEMS core. ## Package and layout — 6-SMD no-lead, 5.0×3.2 mm 6-SMD no-lead package, 5.00×3.20 mm footprint, 0.90 mm seated height. Standard land pattern for 5×3.2 mm oscillators; the four corner pads are the supply and output, the two centre pads are NC or enable — verify the enable polarity against the DSC1122 pinout.","metaTitle":"DSC1122BI2-148.5000 MEMS XO 148.5 MHz LVPECL - Microchip","metaDescription":"Active-production MEMS oscillator, 148.5 MHz LVPECL output, ±25 ppm stability, -40°C to 85°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":"Tube","Ratings":"-","Function":"Enable/Disable","Frequency":"148.5 MHz","Mounting Type":"Surface Mount","Base Resonator":"MEMS","Package / Case":"6-SMD, No Lead","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":"DSC1122","Frequency Stability":"±25ppm","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":"What is the closest pin-compatible alternative in the DSC1122 family?","answer":"The DSC1122 series shares the same 6-SMD footprint, supply range, and enable/disable function across all frequency options.
