The wide range also absorbs rail droop in battery-backed or lightly regulated systems — a single DSC400 can serve multiple board variants that run different core voltages. For a 12.288 MHz output, that is a maximum drift of ±614 Hz — tight enough for a USB audio clock or a CAN bus time base, but not for a GSM reference that demands sub-±10 ppm. If the application needs tighter stability, a TCXO or OCXO in the same footprint would be a different part number. ## Package and layout: the exposed-pad thermal via pattern The 20-VFQFN exposed pad package (5.00 mm x 3.20 mm body, 0.90 mm height) requires a thermal via array under the centre pad to conduct heat to the PCB ground plane. The datasheet's recommended land pattern (not reproduced here) calls for a solder-paste stencil aperture that covers 50–70% of the pad area — a full-coverage stencil risks floating the package. The exposed pad is electrically connected to the die's ground reference, so the via pattern also serves as the low-impedance ground return for the output drivers. Tape & Reel (TR) packaging is standard for the DSC400 series. The 0.50 mm pitch of the VFQFN leads is fine for a two-layer board if the fan-out traces are necked to 0.15 mm under the package; a four-layer board with a dedicated ground plane under the pad is the safer choice for production repeatability. The DSC400-0111Q0116KI1T is listed as Active. The base product number DSC400 covers a family of factory-programmed multi-output oscillators; if this exact frequency set is no longer needed in a future design, a different DSC400 variant with the same footprint and supply range can be ordered without a PCB spin. The DSC400 series does not have a pin-compatible second source from another manufacturer; cross-shopping should compare the full order code against the Microchip DSC400 configurator.","metaTitle":"DSC400-0111Q0116KI1T MEMS XO – 4-Output LVCMOS Clock","metaDescription":"Microchip DSC400-0111Q0116KI1T XO (Standard) with MEMS resonator, 4 LVCMOS outputs at 12.288/14.7456/11.2896 MHz, ±50 ppm stability, -40~85°C, 2.25-3.6V","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Crystals & Oscillators"],"specifications":{"Mfr":"Microchip Technology","Type":"XO (Standard)","Height":"0.035\\\" (0.90mm)","Output":"LVCMOS","Series":"DSC400","Package":"Tape & Reel (TR)","Function":"Enable/Disable","Base Resonator":"MEMS","Package / Case":"20-VFQFN Exposed Pad","Product Status":"Active","lifecycle_stage":"eol_hot","Size / Dimension":"0.197\\\" L x 0.126\\\" W (5.00mm x 3.20mm)","Voltage - Supply":"2.25V ~ 3.6V","Base Product Number":"DSC400","Frequency Stability":"±50ppm","Frequency - Output 1":"12.288MHz","Frequency - Output 2":"14.7456MHz","Frequency - Output 3":"11.2896MHz","Frequency - Output 4":"-","Operating Temperature":"-40°C~85°C","Current - Supply (Max)":"-"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/41a2dcc1573e66d7260ef0cfef766dd1.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Does DSC400-0111Q0116KI1T support enable/disable?","answer":"Yes, the function is Enable/Disable.

The MEMS resonator eliminates the need for external load capacitors. However, the DSC400 is a multi-output device in a 20-VFQFN package — the footprint is different from a standard 4-pin or 6-pin XO.
