That frequency is common in 10G Ethernet, Fibre Channel, and high-speed serial backplanes—the LVPECL swing provides the edge rate needed for short PCB traces without a separate clock buffer. For a 156.2539 MHz carrier that translates to roughly ±3.9 kHz—tight enough for most SERDES reference clock jitter budgets without external VCXO tuning. The MEMS resonator gives this oscillator better shock and vibration immunity than a quartz crystal, and the 2.25V to 3.6V supply range means it can run from a 2.5V or 3.3V rail without an extra LDO. The 6-SMD, no-lead package (5.00mm x 3.20mm, 0.90mm seated height) is a standard footprint shared across the DSC1122 family.","metaTitle":"DSC1122BI2-156.2539T Microchip MEMS XO 156.2539 MHz LVPECL","metaDescription":"Active Microchip DSC1122 series MEMS oscillator, 156.2539 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":"156.2539 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":"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,"stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/9eb455e34e1b4ad4aed847bfc84d48fa.pdf","sourceUrl":null},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/microchip/DSC1122BI2-156.2539T","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/microchip/DSC1122BI2-156.2539T when reusing this data.
