Outputs are configurable as LVCMOS or LVDS, so the same oscillator can drive a CMOS clock input on one lane and a differential LVDS receiver on another — useful when mixing FPGA banks or ASIC reference inputs with different I/O standards. ## Enable/Disable function and temperature range Frequency stability is held to ±50 ppm across that range.","metaTitle":"DSC400-3111Q0088KE1T MEMS XO – 4-Output, LVCMOS/LVDS, Active","metaDescription":"Microchip DSC400-3111Q0088KE1T XO (Standard) MEMS oscillator: 4 independent frequencies (148.25MHz, 12/24MHz, 25/100MHz, 148.25MHz), LVCMOS/LVDS outputs","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":"±50ppm","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":"Is the DSC400-3111Q0088KE1T compatible with a 3.3 V supply?","answer":"Yes. The supply range is 2.25 V to 3.6 V, so a 3.3 V rail is within the operating envelope. The LVCMOS output swing will track the supply voltage."},{"question":"What does the Enable/Disable function do on this oscillator?","answer":"The Enable/Disable pin allows the outputs to be gated off while the oscillator core remains powered. This reduces dynamic power consumption and lets the system disable unused clock lanes during test or low-power standby without cycling the main supply."},{"question":"What is the lifecycle status of the DSC400-3111Q0088KE1T?","answer":"Active.
