A single DSC400-3333Q0089KE1T replaces two separate cans and saves a slot on the board. The LVDS output pair keeps jitter low over the short differential traces to the FPGA or ASIC clock inputs. ## Wide supply rail and ±50 ppm stability Supply range from 2.25 V to 3.6 V covers both 2.5 V and 3.3 V logic rails without a separate LDO — one BOM line serves either rail. ## 20-VFQFN package — layout checklist The 5.00 x 3.20 mm body with 0.90 mm height and an exposed thermal pad under the package requires a via-in-pad or a thermal via array on the PCB to pull heat to the ground plane.","metaTitle":"DSC400-3333Q0089KE1T Microchip XO LVDS 148.35/148.5 MHz","metaDescription":"DSC400-3333Q0089KE1T: Active Microchip XO (Standard), LVDS output, 148.35/148.5 MHz dual frequency, ±50 ppm stability, 2.25-3.6 V supply. 20-VFQFN package.","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":"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":"±50ppm","Frequency - Output 1":"148.35MHz","Frequency - Output 2":"148.5MHz","Frequency - Output 3":"-","Frequency - Output 4":"-","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/173357f954a2b06004a9dae1ef8117da.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is the DSC400-3333Q0089KE1T a drop-in replacement for a standard 7 x 5 mm oscillator?","answer":"No — the 20-VFQFN package with exposed pad has a different footprint and thermal land pattern than a standard 7 x 5 mm oscillator.
