Housed in a 6-SMD no-lead package measuring 3.20 mm x 2.50 mm with a seated height of 0.90 mm. This is a current-design-in part, not a last-time-buy or obsolete device.","metaTitle":"DSC1121CI2-168.0000T MEMS XO 168 MHz CMOS AEC-Q100","metaDescription":"Microchip DSC1121CI2-168.0000T: 168 MHz MEMS oscillator, CMOS output, AEC-Q100, 2.25-3.6V, -40 to 85°C.

The MEMS-based DSC1121 is a drop-in replacement for many quartz XOs of the same package size and output type.

The supply voltage range of 2.25V to 3.6V covers 3.3V rails, and the CMOS output swings rail-to-rail, so it drives 3.3V clock inputs directly."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/microchip/DSC1121CI2-168.0000T","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/microchip/DSC1121CI2-168.0000T when reusing this data.
