Supply voltage spans 2.25V to 3.6V, covering both 2.5V and 3.3V rails — useful when the same BOM must work across multiple logic families. The MEMS resonator construction avoids quartz supply constraints and offers faster startup than a crystal-based oscillator. ## 6-SMD package and Enable/Disable function Housed in a 3.20mm x 2.50mm 6-SMD no-lead package, seated height 0.90mm — fits tight board stacks and high-density layouts.","metaTitle":"DSC1122CI2-155.5200 – 155.52 MHz LVPECL MEMS Oscillator","metaDescription":"Active MEMS XO, 155.52 MHz LVPECL output, ±25 ppm stability, -40°C to 85°C, 2.25V-3.6V supply. 6-SMD package.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Crystals & Oscillators"],"specifications":{"Mfr":"Microchip Technology","Type":"XO (Standard)","Output":"LVPECL","Series":"DSC1122","Package":"Tube","Ratings":"-","Function":"Enable/Disable","Frequency":"155.52 MHz","Mounting Type":"Surface Mount","Base Resonator":"MEMS","Package / Case":"6-SMD, No Lead","Product Status":"Active","lifecycle_stage":"eol_hot","Size / Dimension":"0.126\\\" L x 0.098\\\" W (3.20mm x 2.50mm)","Voltage - Supply":"2.25V ~ 3.6V","Base Product Number":"DSC1122","Frequency Stability":"±25ppm","Height - Seated (Max)":"0.035\\\" (0.90mm)","Operating Temperature":"-40°C ~ 85°C","Current - Supply (Max)":"58mA","Absolute Pull Range (APR)":"-","Spread Spectrum Bandwidth":"-","Current - Supply (Disable) (Max)":"22mA"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/9eb455e34e1b4ad4aed847bfc84d48fa.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/DSC1122CI2-155.5200/alternatives.json"},"ai":{"faq":[{"question":"Can the DSC1122CI2-155.5200 run on a 2.5V supply?","answer":"Yes — the supply range is 2.25V to 3.6V, so 2.5V and 3.3V rails both work without a regulator change."},{"question":"Is the DSC1122CI2-155.5200 RoHS compliant?","answer":"The part is listed as RoHS compliant per Microchip's standard offering for the DSC1122 series."},{"question":"How does the DSC1122CI2 compare to the DSC1001 series?","answer":"The DSC1122 series offers LVPECL output, while the DSC1001 series is limited to LVCMOS/LVTTL.
