Operates from a wide 2.25V to 3.6V supply, covering 2.5V and 3.3V rails without a separate regulator. ## Enable/Disable pin for power management Useful for power-sensitive designs where the clock tree must be gated during sleep modes or fault conditions. Housed in a 6-SMD no-lead package measuring 3.20 mm x 2.50 mm with a seated height of 0.90 mm. Surface-mount reflow profile follows standard lead-free soldering guidelines.","metaTitle":"DSC1122CI2-155.5200T MEMS Oscillator – 155.52 MHz, LVPECL","metaDescription":"Microchip DSC1122CI2-155.5200T: XO (Standard) with MEMS resonator, 155.52 MHz LVPECL output, ±25 ppm stability, -40°C to +85°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":"LVPECL","Series":"DSC1122","Package":"Tape & Reel (TR)","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/DSC1122CI2-155.5200T/alternatives.json"},"ai":{"faq":[{"question":"What is the frequency stability of DSC1122CI2-155.5200T?","answer":"This is a standard industrial-grade stability spec, sufficient for most 10G/25G Ethernet and Fibre Channel reference clock applications."},{"question":"Does DSC1122CI2-155.5200T have an enable/disable function?","answer":"Yes — the part includes an Enable/Disable feature.
