The HCSL (High-Speed Current Steering Logic) output swings 700-900 mV peak-to-peak into a 50-ohm terminated differential pair, matching the input requirements of Intel and AMD chipset clock trees without external level translation. Supply voltage spans 2.25V to 3.6V, so the same oscillator runs from a 2.5V or 3.3V rail — no separate LDO needed for the clock section. Microchip lists the DSC1104BE1-156.2500T as Active. In a multi-oscillator design, gating unused clocks via this pin saves measurable board power without a load switch.","metaTitle":"DSC1104BE1-156.2500T 156.25 MHz HCSL MEMS Oscillator","metaDescription":"Microchip DSC1104BE1-156.2500T XO (Standard) MEMS oscillator, 156.25 MHz HCSL output, 2.25V-3.6V supply, -20°C to 70°C, 6-SMD.","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":"DSC1104","Package":"Tape & Reel (TR)","Ratings":"-","Function":"Standby (Power Down)","Frequency":"156.25 MHz","Mounting Type":"Surface Mount","Base Resonator":"MEMS","Package / Case":"6-SMD, No Lead","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":"DSC1104","Frequency Stability":"±50ppm","Height - Seated (Max)":"0.035\\\" (0.90mm)","Operating Temperature":"-20°C~70°C","Current - Supply (Max)":"42mA","Absolute Pull Range (APR)":"-","Spread Spectrum Bandwidth":"-","Current - Supply (Disable) (Max)":"95µA"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/11b93dcf3fe2344432ea2f214a7ea724.pdf","sourceUrl":null},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/microchip/DSC1104BE1-156.2500T","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/microchip/DSC1104BE1-156.2500T when reusing this data.
