The 2.25V to 3.6V supply range covers both 2.5V and 3.3V rails without an external regulator, simplifying the power tree on a multi-voltage board. ## Enable/Disable control and supply current Housed in a 6-SMD, No Lead package measuring 5.00mm x 3.20mm with a seated height of 0.90mm. The no-lead footprint means the solder joint is under the package body — inspectability is limited, so a 2D X-ray or AOI station is the practical post-reflow check.","metaTitle":"DSC1121BI2-048.0000T MEMS Oscillator","metaDescription":"DSC1121BI2-048.0000T from Microchip Technology: 48 MHz XO (Standard) with CMOS output, ±25 ppm stability, AEC-Q100 qualified.

It is suitable for under-hood and chassis-domain ECUs where the ambient temperature can reach 85°C."},{"question":"What is the output type of DSC1121BI2-048.0000T?","answer":"The output is CMOS, a single-ended rail-to-rail swing that drives standard digital logic inputs directly. No external termination or level translation is needed when connecting to a 2.5V or 3.3V microcontroller clock input."},{"question":"Does DSC1121BI2-048.0000T have an enable/disable function?","answer":"Yes. The Enable/Disable pin lets you gate the clock output. When disabled, the oscillator stops switching but remains powered; the supply current drops from 35 mA max to 22 mA max. This is useful for power-saving modes where the clock must be restored without the start-up delay of a full power cycle."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/microchip/DSC1121BI2-048.0000T","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/microchip/DSC1121BI2-048.0000T when reusing this data.
