Supply voltage spans 2.25 V to 3.6 V, making it compatible with 2.5 V and 3.3 V logic rails without an external regulator. ## LVPECL output and enable/disable function The LVPECL output provides the differential swing and fast edge rates required for high-speed clock distribution to FPGAs, SERDES, or Ethernet PHYs — the 58 mA max supply current reflects the output driver's bias current. ## Active lifecycle — available for new designs","metaTitle":"DSC1122CE5-077.0000T MEMS XO, 77 MHz LVPECL, ±10 ppm, Active","metaDescription":"Microchip DSC1122CE5-077.0000T XO (Standard) with MEMS resonator, 77 MHz LVPECL output, ±10 ppm stability, 2.25-3.6 V supply, -20 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)","Output":"LVPECL","Series":"DSC1122","Package":"Tape & Reel (TR)","Ratings":"-","Function":"Enable/Disable","Frequency":"77 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":"±10ppm","Height - Seated (Max)":"0.035\\\" (0.90mm)","Operating Temperature":"-20°C~70°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/DSC1122CE5-077.0000T/alternatives.json"},"ai":{"faq":[{"question":"Is the DSC1122CE5-077.0000T a direct replacement for the DSC1122CE5-077.0000?","answer":"The base product number DSC1122 is shared, and the suffix 'T' typically denotes Tape & Reel packaging.
