Operating from 1.8V to 3.3V, this oscillator can be driven directly from a 1.8V core rail or a 3.3V I/O rail without an intermediate regulator — useful when the same BOM position must serve multiple voltage domains across a product family. Maximum active supply current is 7.2 mA at 49.0908 MHz; in standby the disable current drops to 15 µA, making it viable for battery-backed RTC or wake-up timer circuits where the clock is gated during sleep. ## Package, footprint, and board-level fit Housed in a 5.00 mm × 3.20 mm 4-SMD, No Lead package with a seated height of 0.90 mm max — a standard footprint that matches many 5.0×3.2 mm quartz oscillators, simplifying a drop-in replacement if the design moves from quartz to MEMS.","metaTitle":"DSC1001BI2-049.0908T MEMS XO – 49.0908 MHz, CMOS, AEC-Q100","metaDescription":"Microchip DSC1001BI2-049.0908T: 49.0908 MHz MEMS XO, CMOS output, ±25 ppm stability, -40°C to 85°C, AEC-Q100.

The DSC1002 series typically adds a spread-spectrum modulation option for EMI reduction. Both share the same MEMS resonator, CMOS output, and package footprint, so the PCB layout is identical — the choice depends on whether you need the standby feature or the spread-spectrum clock."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/microchip/DSC1001BI2-049.0908T","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/microchip/DSC1001BI2-049.0908T when reusing this data.
