The 1.8V to 3.3V supply range lets you run the oscillator from the same rail as the MCU or transceiver without a separate LDO — the 7.2 mA max supply current at 48 MHz is low enough that the rail budget is set by the load, not the oscillator. ## Standby function — gating the clock in low-power modes ## Package and footprint — board-level fit The 4-SMD, No Lead Exposed Pad package measures 7.00 mm x 5.00 mm with a seated height of 0.90 mm — the same footprint as standard 7x5 mm quartz oscillators, so it drops onto existing PCB layouts without a spin.","metaTitle":"DSC1001AI2-048.0000T MEMS XO – 48 MHz, CMOS, AEC-Q100","metaDescription":"Microchip DSC1001AI2-048.0000T: 48 MHz MEMS oscillator, CMOS output, AEC-Q100 qualified, ±25 ppm stability, 1.8V–3.3V supply, standby function.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Crystals & Oscillators"],"specifications":{"Mfr":"Microchip Technology","Type":"XO (Standard)","Output":"CMOS","Series":"DSC1001","Package":"Tape & Reel (TR)","Ratings":"AEC-Q100","Function":"Standby (Power Down)","Frequency":"48 MHz","Mounting Type":"Surface Mount","Base Resonator":"MEMS","Package / Case":"4-SMD, No Lead Exposed Pad","Product Status":"Active","lifecycle_stage":"eol_hot","Size / Dimension":"0.276\\\" L x 0.197\\\" W (7.00mm x 5.00mm)","Voltage - Supply":"1.8V ~ 3.3V","Base Product Number":"DSC1001","Frequency Stability":"±25ppm","Height - Seated (Max)":"0.035\\\" (0.90mm)","Operating Temperature":"-40°C~85°C","Current - Supply (Max)":"7.2mA","Absolute Pull Range (APR)":"-","Spread Spectrum Bandwidth":"-","Current - Supply (Disable) (Max)":"15µA"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/6e16d8c0e20d671fdec1bc4732fc9156.pdf","sourceUrl":null},"ai":{"faq":[{"question":"How can I order the DSC1001AI2-048.0000T or check availability?","answer":"Submit an RFQ with your target quantity and target price; we confirm current pricing and lead time at quote time.
