It is suitable for both new designs and ongoing production builds. Supplied in Tape & Reel (TR) packaging, consistent with automated pick-and-place assembly.","metaTitle":"DSC1121BI5-024.5760T MEMS XO 24.576 MHz CMOS - Microchip","metaDescription":"Active MEMS oscillator, 24.576 MHz, CMOS output, ±10 ppm APR, -40°C to 85°C, 6-VDFN.

When disabled, the output goes high-impedance and supply current drops from 35 mA max to 22 mA max — useful for power gating in battery-operated or duty-cycled systems."},{"question":"Is the DSC1121BI5-024.5760T a direct replacement for a quartz oscillator at 24.576 MHz?","answer":"It is a MEMS-based XO, not a quartz crystal — it includes the resonator and oscillator on-chip. The CMOS output and 2.25V–3.6V supply make it a drop-in for many 24.576 MHz clock inputs on Ethernet PHYs, audio codecs, or FPGA reference clocks, but confirm the footprint (6-VDFN, 5.00mm x 3.20mm) matches your PCB land pattern."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/microchip/DSC1121BI5-024.5760T","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/microchip/DSC1121BI5-024.5760T when reusing this data.
