That pair is common in 10G/25G Ethernet, FPGA reference clocks, and SerDes PHYs where the PLL needs two close-but-distinct reference frequencies. The LVPECL output swings fast enough to drive a 100-ohm differential pair directly – no external biasing network needed for AC-coupled lines. ±50 ppm stability covers most base-T and fibre-channel jitter budgets without a separate VCXO. ## MEMS resonator – why it matters for the BOM That means better shock and vibration tolerance – relevant if the board goes into a fan-cooled chassis or a panel-mount enclosure subject to mechanical stress. No quartz crystal to crack or drift under moderate G-load. Supply voltage spans 2.25 V to 3.6 V, so it runs from a 2.5 V or 3.3 V rail without an extra LDO. ## Package and temperature – board-fit constraints 20-VFQFN with exposed pad, 5.00 mm x 3.20 mm body, 0.90 mm height. Fine for indoor switching gear, test equipment, or office networking. Not for outdoor base stations, engine compartments, or cold-chain storage: those call for the industrial-temp variant of the DSC400 family. No NRND flag. The DSC400 base number covers multiple frequency and stability options, so confirm the full order code before committing.","metaTitle":"DSC400-0202Q0107KE1T MEMS XO – Dual LVPECL","metaDescription":"Microchip DSC400-0202Q0107KE1T MEMS XO, dual LVPECL outputs at 161.1328125 MHz and 164.375 MHz, ±50 ppm stability, 2.25–3.6 V 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":"LVPECL","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":"161.1328125MHz","Frequency - Output 2":"164.375MHz","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/0cecb08ad574fed3be7cf1fcd38d37aa.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What are the exact output frequencies of DSC400-0202Q0107KE1T?","answer":"Output 1 is 161.1328125 MHz, output 2 is 164.375 MHz.
