That 2.048 MHz is the framing rate — this oscillator was designed into telecom timing modules, T1/ line cards, and base station synchronisation circuits where the frequency tolerance matters more than the absolute accuracy of a crystal. ## Standby function — 1 µA power-down current That is the entire oscillator going to sleep — no output, no internal bias. For a battery-backed line card or a remote sensor node that wakes on a periodic schedule, the 1 µA sleep current extends shelf life without a load switch on the 3.3 V rail. Microchip has discontinued the DSC1033CI1-002.0480 — the product status is marked Obsolete. For a board that already carries this oscillator, the only path is surplus or independent distribution.","metaTitle":"DSC1033CI1-002.0480 — Microchip MEMS XO, 2.048 MHz, CMOS","metaDescription":"DSC1033CI1-002.0480 is a Microchip MEMS XO (Standard) at 2.048 MHz, CMOS output, 3.3V, ±50 ppm, -40°C to +85°C.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Crystals & Oscillators"],"specifications":{"Mfr":"Microchip Technology","Type":"XO (Standard)","Output":"CMOS","Series":"DSC1033, PureSilicon™","Package":"Tube","Ratings":"-","Function":"Standby (Power Down)","Frequency":"2.048 MHz","Mounting Type":"Surface Mount","Base Resonator":"MEMS","Package / Case":"4-SMD, No Lead","Product Status":"Obsolete","lifecycle_stage":"eol_hot","Size / Dimension":"0.126\\\" L x 0.098\\\" W (3.20mm x 2.50mm)","Voltage - Supply":"3.3V","Frequency Stability":"±50ppm","Height - Seated (Max)":"0.035\\\" (0.90mm)","Operating Temperature":"-40°C~85°C","Current - Supply (Max)":"3mA (Typ)","Absolute Pull Range (APR)":"-","Spread Spectrum Bandwidth":"-","Current - Supply (Disable) (Max)":"1µA"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/39044fcc9825a23a0d54b2590f18614f.pdf","sourceUrl":null},"ai":{"faq":[{"question":"How can I order the DSC1033CI1-002.0480 or check availability?","answer":"This part is obsolete.
