The LVPECL output delivers the differential swing needed for high-speed serial links (Gigabit Ethernet, Fibre Channel, SONET) — the 155.52 MHz frequency is a standard telecom rate, and the 58 mA max supply current is the budget for the output stage driving a 50-Ω terminated line. ## Package and footprint — 7.0 × 5.0 mm no-lead Housed in a 6-SMD, no-lead exposed pad package measuring 0.276\" × 0.197\" (7.00 mm × 5.00 mm) with a seated height of 0.035\" (0.90 mm).","metaTitle":"DSC1122AI5-155.5200T MEMS XO 155.52 MHz LVPECL ±10 ppm","metaDescription":"Microchip DSC1122AI5-155.5200T MEMS oscillator, 155.52 MHz LVPECL output, ±10 ppm stability, industrial temp range.","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 Exposed Pad","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","Base Product Number":"DSC1122","Frequency Stability":"±10ppm","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/DSC1122AI5-155.5200T/alternatives.json"},"ai":{"faq":[{"question":"Can DSC1122AI5-155.5200T replace other 155.52 MHz oscillators?","answer":"It is a direct functional replacement for any 155.52 MHz LVPECL oscillator in the same 7.0 × 5.0 mm 6-pin footprint, provided the supply voltage and enable polarity match.
