That replaces four discrete quartz cans with one MEMS-based oscillator, freeing up board area and cutting the oscillator line count from four to one. ## Supply and temperature — where this oscillator lives comfortably The supply range spans 2.25 V to 3.6 V, covering 2.5 V and 3.3 V rails without an extra regulator. ## Enable/Disable pin — gating the clock without a load switch The Enable/Disable function lets firmware shut down the outputs during sleep or system reset. That keeps the clock edges off the bus when the downstream logic is unpowered, and saves the quiescent current of four separate oscillators — no extra load-switch FET needed. ## Package and rework — the exposed-pad reality The 20-VFQFN Exposed Pad is 0.90 mm tall. The pad under the package is the ground return and the main heat path — it needs a thermal via array in the PCB to pull heat into the ground plane. Reworking this part: preheat the board to 150°C, hit the pad with hot air at 300°C for 30 seconds, and lift the part without lifting the pad. The exposed pad is large enough that a poor solder joint under it will show up as a missing clock on all four outputs.","metaTitle":"DSC400-1111Q0084KI1 Quad-Output MEMS XO – Microchip, LVCMOS","metaDescription":"Active-production quad-output MEMS oscillator from Microchip.

We source it through independent distribution channels — submit an RFQ with your target quantity and target price, and we confirm availability and current pricing on the quote. No stock-holding claim; every order is quoted to order."},{"question":"Is the DSC400-1111Q0084KI1 a direct replacement for a quartz oscillator?","answer":"Functionally yes — it outputs LVCMOS clocks at the listed frequencies with ±50 ppm stability, the same as a quartz XO. But the underlying resonator is MEMS, not quartz. That means no crystal aging drift and better shock/vibration tolerance, but the jitter profile and phase noise differ from a quartz can. On a board originally designed for a quartz oscillator, the DSC400 will work as a drop-in if the supply voltage (2.25-3.6 V) and output type (LVCMOS) match the original."},{"question":"Does the DSC400-1111Q0084KI1 have an enable/disable pin?","answer":"Yes, the part includes an Enable/Disable function. Pulling the pin low disables the outputs, putting the oscillator into a low-power state. This is useful for power sequencing or gating the clock during system sleep without adding an external load switch."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/microchip/DSC400-1111Q0084KI1","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/microchip/DSC400-1111Q0084KI1 when reusing this data.
