The 2.048 MHz frequency is a common T1/ and synchronous Ethernet reference clock — if your board generates or recovers a 2.048 MHz frame pulse, this oscillator serves that slot directly without a PLL multiplier. ## Standby function and low-power disable current In a battery-powered design that clocks only intermittently — a remote sensor waking to transmit on a 2.048 MHz SPI bus — the standby current is negligible against the battery self-discharge. Active draw is 3 mA typical at 2.048 MHz. If you are filling a BOM line for a production run, confirm the required quantity before committing to a board spin — a functional replacement will likely require a different order code and possibly a layout change. ## Package and footprint — 4-SMD no-lead The oscillator is supplied in a 4-SMD, No Lead package measuring 3.20 mm x 2.50 mm with a seated height of 0.90 mm. No lead frame means the solder joints are under the package; inspect the fillet after reflow to confirm wetting.","metaTitle":"DSC1033CI1-002.0480T MEMS Oscillator 2.048 MHz CMOS XO","metaDescription":"Microchip DSC1033CI1-002.0480T XO (Standard) 2.048 MHz CMOS output, 3.3V, ±50 ppm stability, -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":"Tape & Reel (TR)","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can I order the DSC1033CI1-002.0480T or check current availability?","answer":"The DSC1033CI1-002.0480T is obsolete.
