No last-time-buy window or successor part has been announced. ## MEMS vs quartz: what the resonator choice means","metaTitle":"DSC1122BI2-120.0000 120 MHz LVPECL MEMS Oscillator","metaDescription":"DSC1122BI2-120.0000 XO (Standard) from Microchip, 120 MHz LVPECL output, ±25 ppm stability, -40°C to 85°C, 6-SMD.

You can substitute a different frequency or stability grade within the series without a board layout change, as long as the output type (LVPECL) and supply voltage range match."},{"question":"What is the difference between MEMS and quartz oscillators?","answer":"MEMS oscillators use a silicon micro-electromechanical resonator instead of a quartz crystal. They typically start up in under 1 ms (vs 5–10 ms for quartz), withstand higher shock (50,000 g vs ~3,000 g), and have no mechanical aging drift. The trade-off is that phase noise at very close-in offsets (10 Hz–1 kHz) can be higher than a good quartz oscillator — check the jitter spec for your PLL bandwidth."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/microchip/DSC1122BI2-120.0000","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/microchip/DSC1122BI2-120.0000 when reusing this data.
