LVPECL is a differential pair — the 156.2539 MHz signal needs a termination at the receiver. The output swing is large enough to drive a clock fan-out buffer or a PLL reference input directly, but the trace pair must be impedance-controlled to keep the edge rates clean. ## Package and reflow — 7.0 mm × 5.0 mm, MSL check before the oven The 6-SMD no-lead exposed-pad package measures 7.0 mm × 5.0 mm with a seated height of 0.90 mm. Before the reflow oven, confirm the moisture sensitivity level (MSL) on the reel label. The MEMS die inside is sealed, but the package construction can trap moisture — if the MSL rating is 3 or higher and the floor life has been exceeded, a 24-hour bake at 125 °C is required or the part popcorns during reflow.","metaTitle":"DSC1122AI2-156.2539T MEMS XO, 156.2539 MHz LVPECL, Active","metaDescription":"Microchip DSC1122AI2-156.2539T XO (Standard), 156.2539 MHz LVPECL output, ±25 ppm stability, -40 to 85 °C, MEMS resonator, 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 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":"±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/DSC1122AI2-156.2539T","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/microchip/DSC1122AI2-156.2539T when reusing this data.
