MEMS resonators are inherently more resistant to vibration and mechanical shock — the frequency shift under 50 g random vibration is typically an order of magnitude lower than a quartz equivalent, which matters for equipment mounted near rotating machinery or in transport. Frequency stability is ±20 ppm absolute pull range — tight enough for 100BASE-TX Ethernet and USB 2.0 full-speed clocking without external trimming. ## Industrial temperature and package constraints The 6-VDFN package measures 5.00 mm x 3.20 mm with a seated height of 0.90 mm — a low-profile, surface-mount footprint that fits tight PCB stack-ups. ## Active production — no design-in risk","metaTitle":"DSC1121BI3-100.0000 MEMS Oscillator 100 MHz CMOS - Microchip","metaDescription":"Active DSC1121BI3-100.0000 XO, 100 MHz CMOS output, 2.25-3.6 V, -40 to 85 C, 6-VDFN.

The DSC1121BI3-100.0000 is a drop-in functional replacement for a 100 MHz CMOS quartz XO in the same 6-VDFN footprint and supply range. The MEMS resonator eliminates quartz aging drift and improves vibration tolerance, but the output timing and logic levels are identical. Confirm the Enable/Disable logic polarity matches your circuit — the DSC1121 uses standard active-low enable per the series datasheet."},{"question":"Is the DSC1121BI3-100.0000 compatible with a 3.3 V supply?","answer":"Yes. The CMOS output swings rail-to-rail, meaning a 3.3 V supply produces a 3.3 V logic-high level compatible with 3.3 V LVCMOS inputs."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/microchip/DSC1121BI3-100.0000","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/microchip/DSC1121BI3-100.0000 when reusing this data.
