When disabled, the maximum supply current drops from 35 mA to 22 mA — useful for low-power sleep modes in battery-backed automotive modules or IoT gateways where every milliwatt counts. The supply voltage accepts 2.25 V to 3.6 V, covering the common 2.5 V, 3.0 V, and 3.3 V logic rails without an external regulator. The 6-SMD no-lead package measures 7.0 mm × 5.0 mm with a seated height of 0.90 mm — a standard footprint that reflows on a typical lead-free profile with no special pad geometry. ## Active — no obsolescence concern Microchip lists the DSC1121NE5-020.0000T as Active. The base product number DSC1121 covers the full family, so if a different frequency or stability grade is needed, the same package and pinout applies across the series.","metaTitle":"DSC1121NE5-020.0000T MEMS XO 20 MHz AEC-Q100","metaDescription":"Microchip DSC1121NE5-020.0000T MEMS oscillator, 20 MHz CMOS output, ±10 ppm stability, AEC-Q100 qualified.

MEMS oscillators are inherently more resistant to vibration and mechanical shock, and they do not exhibit the frequency drift from crystal aging that quartz does. The trade-off is that quartz can sometimes achieve tighter absolute initial accuracy, but the ±10 ppm stability of this part is sufficient for most automotive and industrial clock trees. For a direct quartz alternative in the same 7.0 mm × 5.0 mm footprint, look at Microchip's DSC1001 series (same package, same pinout) — the difference is the resonator technology, not the"}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/microchip/DSC1121NE5-020.0000T","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/microchip/DSC1121NE5-020.0000T when reusing this data.
