The seated height is 0.90 mm max. Standard surface-mount reflow profiles apply; the exposed pad requires a solder-paste stencil aperture matching the datasheet land pattern for reliable solder-joint formation.","metaTitle":"DSC1122AE2-134.4000T Microchip 134.4 MHz LVPECL MEMS","metaDescription":"Active Microchip DSC1122AE2-134.4000T XO (Standard) MEMS oscillator, 134.4 MHz LVPECL output, ±25 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":"134.4 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":"-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/DSC1122AE2-134.4000T/alternatives.json"},"ai":{"faq":[{"question":"What is the frequency stability of DSC1122AE2-134.4000T?","answer":"±25 ppm across the -20 to +70 °C operating temperature range. This stability grade is typical for a standard XO and meets the jitter budget for most 1000BASE-T, SATA, and PCIe Gen1/2 reference clocks."},{"question":"Can DSC1122AE2-134.4000T replace a quartz oscillator at the same frequency?","answer":"Yes, if the board expects a 134.4 MHz LVPECL input and the supply voltage falls within 2.25-3.6 V. The MEMS oscillator is pin-compatible with standard 7x5 mm SMD oscillators. The Enable/Disable function and output type must match the original socket; confirm the footprint and logic family before committing. No direct second-source or drop-in replacement is listed, but any DSC1122-series part with the same frequency, output, and package could be a functional equivalent — verify the stability and temperature grade."},{"question":"Is DSC1122AE2-134.4000T compatible with a 3.3 V supply?","answer":"The LVPECL output logic levels track the supply — at 3.3 V the swing is approximately 800 mV peak-to-peak centered at Vcc - 1.3 V. Ensure the receiving device's input common-mode range accepts this."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/microchip/DSC1122AE2-134.4000T","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/microchip/DSC1122AE2-134.4000T when reusing this data.
