The MEMS resonator replaces a quartz crystal, giving it faster start-up and better shock tolerance than a conventional crystal oscillator — useful in portable or vibration-prone equipment. Microchip lists the DSC1033BI1-048.4610T as Obsolete. Available now through independent surplus channels; quantities are lot-specific and confirmed at RFQ. ## Standby function and power budget The part includes a Standby (Power Down) function that drops the supply current to 1µA max when disabled — a useful feature for battery-powered designs where the clock is gated during sleep. Active draw is 4mA typical, so the standby savings are meaningful in a low-duty-cycle system.","metaTitle":"DSC1033BI1-048.4610T MEMS XO 48.461 MHz CMOS Obsolete","metaDescription":"Microchip DSC1033BI1-048.4610T XO (Standard) MEMS oscillator, 48.461 MHz, CMOS output, 3.3V, ±50ppm, -40°C~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":"48.461 MHz","Mounting Type":"Surface Mount","Base Resonator":"MEMS","Package / Case":"4-SMD, No Lead","Product Status":"Obsolete","lifecycle_stage":"eol_hot","Size / Dimension":"0.197\\\" L x 0.126\\\" W (5.00mm x 3.20mm)","Voltage - Supply":"3.3V","Frequency Stability":"±50ppm","Height - Seated (Max)":"0.035\\\" (0.90mm)","Operating Temperature":"-40°C~85°C","Current - Supply (Max)":"4mA (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can I order DSC1033BI1-048.4610T or check availability?","answer":"This part is obsolete, so it is not stocked in volume.
