The 0.50 mm pitch QFN footprint needs a 4-layer board for clean fan-out of the 20 terminals.

We source it through independent distribution channels and quote it to order against your BOM quantity. Availability and current pricing are confirmed at the time of RFQ — no stock-holding claim is made on this page."},{"question":"Is the DSC400-1111Q0085KE1T equivalent to a standard quartz oscillator?","answer":"Functionally yes — it provides the same LVCMOS clock outputs as a quartz XO. Structurally no: it uses a MEMS resonator instead of a quartz crystal, and the 20-VFQFN package with exposed pad is not pin-compatible with a 4-pin or 6-pin quartz oscillator. A board layout change is required to swap between the two."},{"question":"Does the DSC400-1111Q0085KE1T have an enable/disable function?","answer":"Yes — the function is listed as Enable/Disable. This allows individual output channels to be gated under firmware control, reducing power consumption in idle states without removing the supply rail."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/microchip/DSC400-1111Q0085KE1T","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/microchip/DSC400-1111Q0085KE1T when reusing this data.
