Outputs are configurable as LVCMOS or LVDS, letting the same device drive a mix of logic families without external level translation. Supply voltage spans 2.25 V to 3.6 V, covering common 2.5 V and 3.3 V rails — no separate regulator needed for the oscillator. ## Package and layout fit for space-constrained boards Housed in a 20-VFQFN with exposed pad, the 5.00 mm × 3.20 mm footprint and 0.90 mm height suit dense PCB stacks where height clearance is tight. ## Active lifecycle with no obsolescence pressure","metaTitle":"DSC400-3111Q0088KE2T MEMS XO – Quad Output, LVCMOS/LVDS","metaDescription":"Microchip DSC400-3111Q0088KE2T: MEMS XO, 4 outputs (148.25MHz, 12/24MHz, 25/100MHz, 148.25MHz), LVCMOS/LVDS, ±25ppm, 2.25-3.6V, -20°C~70°C, 20-VFQFN.","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, LVDS","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":"±25ppm","Frequency - Output 1":"148.25MHz","Frequency - Output 2":"12MHz, 24MHz","Frequency - Output 3":"25MHz, 100MHZ","Frequency - Output 4":"148.25MHz","Operating Temperature":"-20°C~70°C","Current - Supply (Max)":"-"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/2723b9747a2eae277fa05951882c31f9.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the output type of the DSC400-3111Q0088KE2T?","answer":"LVCMOS and LVDS — each output can be configured to either standard, so the same oscillator drives both single-ended and differential clock lines."},{"question":"Can the DSC400-3111Q0088KE2T run from a 3.3 V supply?","answer":"Yes.
