Supply range is 2.25V to 3.6V — covers 2.5V and 3.3V rails without an external LDO; the wide input tolerance simplifies BOM consolidation across multiple voltage domains. Package is 6-VDFN, 5.00mm x 3.20mm, seated height 0.90mm — standard footprint for MEMS oscillators; the small profile fits under shielding cans or in tight card-edge clearance. Supplied in Tape & Reel (TR) — standard for automated pick-and-place; store the reels in a dry cabinet if the MSL level requires it (confirm on the reel label).","metaTitle":"DSC1121BI1-014.8946T MEMS XO 14.8946 MHz CMOS - Microchip","metaDescription":"DSC1121BI1-014.8946T XO (Standard) from Microchip DSC1121 series.

MEMS parts typically have better shock and vibration tolerance, shorter lead times, and no quartz supply volatility. The electrical interface (CMOS output, supply voltage, enable/disable) is identical to a standard XO — the BOM footprint is the same."},{"question":"How do I enable/disable the output on this oscillator?","answer":"The Enable/Disable pin (pin 1 on the 6-VDFN package) controls the output. Drive it high (or leave it floating with the internal pull-up) to enable the clock output; drive it low to disable the output. When disabled, the oscillator core remains powered but the output buffer is tri-stated, drawing 35µA max."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/microchip/DSC1121BI1-014.8946T","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/microchip/DSC1121BI1-014.8946T when reusing this data.
