Frequency stability is ±50 ppm — tight enough for 100BASE-TX Ethernet jitter budgets and most automotive serial links. ## Package and board-fit Housed in a 6-SMD no-lead package measuring 3.20 mm x 2.50 mm with a seated height of 0.90 mm — a common footprint shared with many quartz and MEMS oscillators. Surface-mount reflow profile follows standard lead-free solder profiles; no special bake-out required for MSL level 1.","metaTitle":"DSC1121CE1-033.3333 MEMS XO 33.3333 MHz CMOS AEC-Q100","metaDescription":"Microchip DSC1121CE1-033.3333 XO (Standard) 33.3333 MHz CMOS MEMS oscillator, AEC-Q100 qualified, 2.25V-3.6V supply, 6-SMD no-lead package.

The DSC1122 series adds a standby mode with lower disable current. Both share the same 6-SMD package, supply range, and AEC-Q100 qualification — the choice depends on whether the application needs the deeper power-down of the DSC1122."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/microchip/DSC1121CE1-033.3333","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/microchip/DSC1121CE1-033.3333 when reusing this data.
