This replaces up to four discrete crystal oscillators on the board — the BOM count drops while keeping the timing tree independent per rail. Operating from 2.25 V to 3.6 V, the LVCMOS outputs are compatible with 2.5 V and 3.3 V logic families without an external level translator. An enable/disable function on the oscillator allows the outputs to be tri-stated — useful for power gating unused clock domains during low-power sleep modes. The 20-VFQFN exposed pad package (5.00 mm x 3.20 mm, 0.90 mm height) requires a thermal land on the PCB for proper heat dissipation and mechanical stability.","metaTitle":"DSC400-1111Q0111KI1T MEMS XO - 4 Outputs, LVCMOS, Active","metaDescription":"Microchip DSC400-1111Q0111KI1T XO (Standard) with 25/20/24 MHz outputs, LVCMOS, ±50 ppm, -40°C to +85°C, 20-VFQFN.

The LVCMOS outputs operate across a 2.25 V to 3.6 V supply range, so the output swing at 2.5 V supply meets the VIH/VIL thresholds of standard 2.5 V logic families without a level shifter."},{"question":"Does DSC400-1111Q0111KI1T have a standard enable/disable functionality?","answer":"Yes. The device includes an enable/disable function that tri-states the outputs when disabled, allowing the clock tree to be gated for power savings or test modes."},{"question":"What is the closest pin-compatible alternative to DSC400-1111Q0111KI1T in the DSC400 family?","answer":"The DSC400 series includes multiple frequency-configuration variants in the same 20-VFQFN package and pinout. The base product number DSC400 covers the family; the specific output frequency set and stability grade define the full order code. A direct alternative would be another DSC400 variant with the same package and supply voltage but different output frequencies — confirm the BOM's required frequencies before substituting."},{"question":"Is DSC400-1111Q0111KI1T RoHS compliant?","answer":"The evidence does not explicitly list RoHS compliance status. The part is supplied in a standard 20-VFQFN package typical of RoHS-compliant components, but the buyer should verify the specific date-code and manufacturer's RoHS certificate at the time of ordering."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/microchip/DSC400-1111Q0111KI1T","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/microchip/DSC400-1111Q0111KI1T when reusing this data.
