HCSL swings 700-900 mV peak-to-peak into a 50-ohm termination to ground, which means the oscillator drives the PCIe clock tree directly without a level translator. The available frequency range of 10 MHz to 460 MHz covers PCIe Gen 1 through Gen 4 reference clock requirements (100 MHz nominal) and most Ethernet SerDes reference frequencies up to 312.5 MHz. Total frequency stability of ±10 ppm keeps the accumulated jitter within the PCIe Base Spec timing budget for Gen 3 and below; for Gen 4 designs the system PLL absorbs the remaining wander. ## MEMS resonator vs quartz trade-offs The blank (user-programmable) variant means the factory programs the output frequency per the order code — the buyer specifies the frequency at order time, and the device ships pre-configured. No field programming is possible. ## Automotive-grade operating envelope The MEMS die and ASIC are qualified to the AEC-Q100 stress tests including pre-conditioning, temperature cycling, and HAST. Maximum supply current is 42 mA across the full frequency range and temperature span. Surface-mount mounting; the tube packaging (50 per tube) is standard for pick-and-place feeders. No special moisture sensitivity level is stated — treat as MSL 1 unless the reel label indicates otherwise.","metaTitle":"DSC8104AI5 MEMS XO, HCSL Output, 10-460 MHz, AEC-Q100","metaDescription":"Microchip DSC8104AI5 MEMS-based XO (Standard) with HCSL output, 10 MHz to 460 MHz range, ±10 ppm stability, AEC-Q100 qualified.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Crystals & Oscillators"],"specifications":{"Mfr":"Microchip Technology","Type":"XO (Standard)","Output":"HCSL","Series":"DSC8104","Package":"Tube","Ratings":"AEC-Q100","Function":"Standby","Mounting Type":"Surface Mount","Base Resonator":"MEMS","Package / Case":"6-SMD, No Lead","Product Status":"Active","lifecycle_stage":"eol_hot","Size / Dimension":"0.276\\\" L x 0.197\\\" W (7.00mm x 5.00mm)","Voltage - Supply":"2.25V ~ 3.6V","Programmable Type":"Blank (User Must Program)","Base Product Number":"DSC8104","Frequency Stability":"-","Height - Seated (Max)":"0.035\\\" (0.90mm)","Operating Temperature":"-40°C~85°C","Current - Supply (Max)":"42mA","Available Frequency Range":"10 MHz ~ 460 MHz","Spread Spectrum Bandwidth":"-","Frequency Stability (Total)":"±10ppm"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$6.9800","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/b114477e2ae1e9c8bbb9420182bdf8b9.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the output type of the DSC8104AI5?","answer":"The output is HCSL (High-Speed Current Steering Logic), which is the standard differential clock format for PCIe reference clock distribution.
