HCSL (High-Speed Current Steering Logic) outputs are the typical clock format for PCIe reference clocks, requiring a 50-ohm termination to ground at the receiver — the oscillator itself does not include on-die termination, so the PCB layout must place the termination resistors close to the load. Frequency stability is rated at ±50 ppm over the -20°C to 70°C commercial temperature range — this is tight enough for a 100 MHz PCIe Gen1/2 reference clock, where the total system budget typically allows ±300 ppm including the PLL tracking error. The supply voltage range of 2.25V to 3.6V covers 2.5V and 3.3V core rails without an external LDO — the internal regulator rejects supply ripple, so a clean 3.3V from a switching regulator is sufficient as long as the ripple stays below 50 mVpp at the switching frequency. No NRND or EOL notice has been published for this base product number.","metaTitle":"DSC400-0404Q0058KE1T XO MEMS Oscillator – Microchip, 100 MHz","metaDescription":"DSC400-0404Q0058KE1T from Microchip Technology: XO (Standard) MEMS oscillator, dual 100 MHz HCSL outputs, ±50 ppm stability, 2.25-3.6V supply, -20°C to 70°C","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":"HCSL","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":"100MHz","Frequency - Output 2":"-","Frequency - Output 3":"100MHz","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/b1fa89bbb593bb9f15bbf883a84023ea.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Who supplies the DSC400-0404Q0058KE1T and how is it quoted for volume?","answer":"Microchip Technology is the manufacturer.
